This diagram illustrates the flexible configuration options of WinCC. - Comprehensive visualization functions for multiple operators are compiled using multi-station systems. - Process interconnection is handled by an OS server. - All other clients are connected to a server via a PC network.
- The client receives all data from the server. - Higher-level computers from the plant control level can also access the WinCC database at any time via the terminal bus. - In a harsh industrial environment, the SIMATIC Industrial Ethernet process bus can also be used as the terminal bus, however this will decrease the performance of the process interconnections to the ASs.

OS with multiple servers A distributed OS, with up to 12 servers/server pairs and up to 32 terminals for each server/server pair. Each server communicates with the ASs assigned to it (different ASs for each server). CAS
One server/pair of servers can also be used as a so-called CAS (central archive server). This is connected to the other servers/server pairs (max. 11) only via the terminal bus, and takes over their archives.
Client
A terminal (OS client) can simultaneously request data from max. 12 servers and display these data on a screen, if applicable.
Reference client
Can be referenced as a copy of an OS client (saves configuration and synchronization of the client projects following modifications)
Special client
An OS client itself can function as a Web server or Open PCS 7 station, and arrange a controlled access from other clients (typically from other networks) to the OS server data.

SITRAIN Training for Automation and Drives
Operator station (OS) In PCS 7 you distinguish between two types of operator stations: OS server and OS client OS server
An OS server centrally contains the Data Manager of the operator control and monitoring system with which it handles the PLC communication links required in the system and the associated tag management. It also contains the alarm logging and measured value archives. Usually there is no operator control and monitoring functionality available on an OS server to ensure that capacity is channeled into the main tasks.
OS client
The purpose of the OS client is to enable operator control and monitoring of the processes. The data manager of the OS server provides the tag states of the individual process tags that are linked to the selected process picture. An OS either consists of one computer (single station system) or a computer network (multi-station system) that has both read and write access to the data in the automation systems. To attain operator control and monitoring functionality, the "WinCC" SCADA software package with process control options is used. This package can be supplemented by options according to the task.
Special case
Training Center for Automation and Drives
An OS client itself can be used as a server for other clients (Web OS or Open PCS 7). In this case it is not operated by a plant operator. It is only a "switchboard" between specific OS servers and the other PCs.

WinCC Editors (Standard) Graphics Designer - A vector-oriented graphics program for creating process pictures
Alarm Logging - Records and archives events
Tag Logging - Used to transfer data from running processes and prepare them for display in trends and tables as well as to archive them.
Report Designer - Integrated reporting system with user-defined layouts for time-controlled or event-driven documentation of messages, operations, and archive contents
Global Script General term for functions and actions that, depending on the type, can be used project-wide or even across several projects. As an alternative you can use the editors for C script or VB script.
Text Library - This is where the foreign language output texts are defined for the configured message texts. The foreign language texts are then output in the selected runtime language.
User Administrator - Used during active runtime to assign and check users' access permissions to the individual editors in the configuration system and runtime system.
Cross-Reference - Used to locate and display all points of use of objects such as tags, pictures and functions.

SITRAIN Training for
Date: 12.12.2006 File:ST-PCS7SYS_V70B&B.10
Automation and Drives
This editor is for configuring and initializing the screen and picture setting for the current WinCC project. It sets up the message system, defines the dimensions for the area overview picture and establishes the basic data for the OS project, e.g. default screen layout.
Picture Tree Manager This manager is used to manage a hierarchy of process cells, units and pictures of the Graphics Designer. The Picture Tree Manager also provides the following functions: · Creating and changing a project hierarchy · Support during definition of process cells and units. · Support when assigning pictures to these process cells and establishment of order among the pictures created in the Graphics Designer. · You can navigate in the hierarchy tree to select the required pictures during runtime. The Picture Tree Manager influences the user administrator, the group display and the text library. Lifebeat Monitor
A lifebeat monitor computer performs sign-of-life monitoring centrally. The lifebeat monitor monitors all the server computers, client computers, multi-client computers, and, above all, the automation systems that can be reached over PC networks and industrial networks and that are assigned to the lifebeat monitor (lifebeat objects).
Time Synchronization Allows the same time of day to be set for all stations from a central location. This requires the presence of a time master. Audio alarm
Training Center for Automation and Drives
You use the "Horn" editor to configure which signals are to be triggered when specific messages occur.

SIMATIC PCS 7 System Training HMI/Operator Control and Monitoring
WinCC (PCS 7 - Basic Options) SFC Visualization - The SFC visualization provides the operator with the option of monitoring and controlling the SFC chart in SFC-compatible view mode on the OS, e.g. Start, Hold and Stop the sequencer.
Client Server - The client server functionality in WinCC provides the capability to operate multiple coordinated operator control and monitoring stations in one common group with networked automation systems.
Redundancy - Redundancy provides the capability to operate two interconnected server PCs in parallel, so the PCs can monitor each other. Both OS servers will operate in parallel and have their own process connections to the ASs. To avoid an "unbalance" in the client supply, clients can be distributed among both servers. If one of the two server computers fails, the second server assumes control of the entire system including the supply of all connected clients. After the failed server is restored, the contents of all the message value archives and process value archives are copied to the other (now operative) server.
User Archives - User archives are a database system that users can configure themselves. This allows you to continuously save data from technical processes to a server PC and display the data online in runtime. In addition, it is possible to store recipes and setpoint specifications for the connected controllers in the user archives and to transfer this data to the controllers if required.

OS optional packages increase the functionality of the operator stations as needed.
Storage Plus
AddOn. Using Storage Plus you can access data that were swapped out from the archive backup. Storage Plus is installed on an external PC. From there, you can manage and visualize the data that were swapped out. Storage Plus can also be used to manage reports in file format and batch data. Version 5 project data that were swapped out can be converted and then processed further and visualized with Storage Plus. CAS Central archive server. A CAS is particularly useful if larger data amounts are to be archived. The data of the CAS can be displayed using the OS terminals. SFC visualization You can use this option to graphically display the sequence configured with SFC on the ES in the same form on the OS. From an overview picture, for example, you can open the step and transition displays and the step comments or display the current dynamically-supplied step enabling conditions and their status information. Signal module This module adds hardware (including drivers) to the PCS 7 message system for acoustic signaling and acknowledging of events. Is configured using the audio alarm editor. Multi-VGA If you require several operator communication channels on one operator terminal, you can set up a maximum of four process monitors on one operator terminal. Chip card reader This reader enables access control for operator stations. You can also set up different authorization levels, which the chip card can check. You can also configure an additional password ("electronic signature") for enhanced access protection in particularly sensitive systems. Time-of-day synchronization Additional packages are available that can be used as the time master in the system. These packages include the SICLOCK TM real-time transmitter in GPS or DCF 77 versions. Web Navigator Operator control and monitoring via the Internet. Open PCS 7 OPC and OLE/DB server for access of other PCs (clients) to PCS 7. Training Center for Automation and Drives

Automation and Drives
This is where all variables (tags) for the computer are defined/stored. A distinction is made between internal (local) tags and process tags. The connection to the S7 ASs is made via the S7 drivers. The channel DLL and the relevant channel unit are selected during the "Compile OS" operation according to the hardware for this connection.
Internal Tags
For SIMATIC PCS 7, the internal tags are generated to some extent by the OS Project Editor and to some extent during OS compilation.
Process Tags
Process tags refer to the various AS systems. They are usually generated by the "Compile OS" operation. You can add customized tags, as needed.
Note
If a tag is to be linked to an object in the Graphics Designer, the tag can be selected in a dialog window from the ES or WinCC view. The ES view shows all parameters (tags) of the ASs, which may not yet exist as WinCC tags. They become WinCC tags during the Compile OS operation; and also in part when tags of the ES view are inserted this takes place virtually concealed in the background). After compilation (in the background) these tags become visible in the WinCC view. For PCS 7, the ES view is used preferentially (direct access to names of the blocks/tags configured in the ES with plant hierarchy). All of the tags are listed by default. You can apply filters with an asterisk (*) to expand the selections. Example: The PLANT1*TIC* filter causes all names that begin with "PLANT1" and contain the text string "TIC" to be listed.
Structure Types
This is where, for example, operator-controllable block types are shown (after the Compile OS operation). Below the individual structure types (e.g., CTRL_PID), the specific instance names of the relevant type are managed = process tag names.

Compile OS
This operation must be used to transfer the data that currently exist only in the AS project in a suitable format to the OS database. This requires that the AS charts themselves have been compiled beforehand, the plant folders have also been assigned, and a picture has been inserted in the PH level defined as the OS area.
Dialog 1
Here you can check or change the OS area assignment if necessary.
Dialog 2
Here you confirm or select the S7 connection (which you have created in NetPro) that is to be used for the OS to exchange data with the AS.
Dialog 3
Here you can define the scope of the data to be taken into consideration. For the first compilation, only a full compilation is offered; afterwards, you can choose to compile the changes only. A memory reset only applies to data that were generated by a previous compilation.
Dialog 4
This message box is only displayed if you have made changes to the associated AS but have not yet compiled the changes.
Note
Block icons are always considered/generated if their generation has been enabled in the CFC or in the process object view.

Result of the OS Compilation The OS compilation primarily affects the following WinCC components: Driver
The driver, the so-called channel DLL (S7 PROTOCOL SUITE) is inserted, containing a UNIT (Industrial Ethernet) in which the logical connection (1) is created to the AS (S7-AS01). All OS-relevant tags are created under this connection; they can be updated over the system bus if necessary.
Internal variables
These internal tags (2) are created for internal purposes, and do not have a connection to the AS.
Structure Tags
The structured data (3) types from the AS are listed here. For example, under the "CTRL_PID" type, all of the closed-loop instances are listed that are marked as HMI-capable (default setting).
Alarm Logging
The alarms (4) from message-capable blocks are entered here.
Text Library
Language-dependent texts for Alarm Logging (5) are entered here; they can be seen in the messages and some are also displayed in the operator interface (for online language changeover).
Picture Hierarchy
The picture hierarchy derived from the "Plant View" is automatically configured through the Picture Tree Manager (6) (if this option is set). The picture hierarchy assists navigation during runtime via a) Overview area and b) Picture navigation keys (arrow keys) in the standard function key area of the OS.

SITRAIN Training for Automation and Drives
Starting in PCS 7 Version 5, when a new OS project is created a file with typicals is created and stored in the \GRACS directory: @@PCS7TYPICALS.PDL. The configuring engineer can assign an attribute to his or her pictures in the plant hierarchy, so that the block icons belonging to the standard code blocks are automatically inserted in the pictures during OS compilation and are also automatically connected to the correct process tag. In PCS 7 Version 7 and higher, these attributes are automatically set, but can also be deactivated. Double-clicking on a block icon during runtime results in the display of the faceplate in the standard view. Clicking the button with the black down arrow allows you to switch between views for maintenance, messages, parameters, limits, trends or batch, depending on the respective block icon. If you click the button for the loop display instead, the entire loop display opens with all its views.

Overview Area
Depending on the graphics resolution selected, up to 36/48/64 plant areas are displayed here, corresponding to the plant view of the project. The group displays show whether there is a fault in the associated area. If you use the arrow icon next to the area name, you can overlay the part of the Picture Tree for this area and directly select the subarea. The overview area is always visible during runtime.
Working Area
Picture window showing process pictures with static and dynamic elements in compact overview or detail view. The operator selects the picture in the overview area. Process pictures are used for operator control and monitoring of process states Entering setpoints, setting parameters, acknowledging messages, controlling SFC sequencers Monitoring fill levels, temperatures, output states and messages With some objects it is possible to make operator input contingent on operator rights, e.g. controller parameters of the PID controller via the PID faceplate.
Key set
Training Center for Automation and Drives
The pre-defined key set in PCS 7 allows you to select typical process information (such as alarm logging, process tag information) or system operator inputs (such as logging on or deactivating the OS).

Preparatory exercise
Preparation of PH Block icons
Prepare the project in order to create the picture hierarchy during compilation of the OS and to generate the icons for operable blocks in this picture hierarchy. To do this, carry out the actions described below. ------------------------------------------------------------------------------------------------------In the plant hierarchy PH, the picture names, e.g. Picture(7), are adapted to more meaningful names. In order to automatically insert block icons into the process pictures during compilation, a properties setting is required for all process pictures in which the icons are desired. If the pictures are inserted in the PH, the property is already activated and must therefore be deactivated if not required (with V7.0 and higher). Right-click and select Properties Block icons tab and select/clear the check box to activate/deactivate automatic insertion. The block icons are obtained from the @@PCS7Typicals.PDL picture. It is recommendable to create one or more copies, and to carry out changes or extensions there as required. If these copies are created with the names @PCS7TypicalsXYZ.PDL (XYZ can be any value: 1, 2, abc, version1, etc.) the symbols displayed there for the standard blocks are incorporated in pictures. If you double-click in runtime, the desired process values and statuses are displayed in the form of so-called faceplates. After insertion, these icons are automatically linked to the associated process tags during OS compilation.

The PCS 7 faceplates are now inserted as a change function with "Compile OS" or "Create/update block icons". -
If a change is made in the CFC, the associated picture is updated.
- If one of the template pictures "@@PCS7Typicals.PDL", @PCS7Typicals.PDL or @PCS7TypicalsXYZ.PDL is changed, all plant pictures are updated. When the icons are generated in the pictures (manually or through compilation), the "@@PCS7Typicals.csv" file is also created in the main directory of the OS project. It is noted internally whether changes are relevant for creating/updating the block icons and, if so, which ones. If this option (block icons) is to be set multiple times, the "Process object view" can be called for this purpose (see slide). First select the project or hierarchy in the left window, then select the General tab in the right window. In the "Filter by column" box, select Type and in the Display box, select "picture". All pictures of the described hierarchy branch are listed in a table. In the "Block icon" column, you can now make multiple selections, then right-click and select Set or Reset to apply the desired setting to all the selected pictures at once. Note 2

to display the above dialog box. This displays the hierarchy levels containing pictures with the "Derive faceplates from PH" option selected. If "Lower hierarchy levels included" =1, the following is specified in the above example: For picture "UnitAi" in PRO_OS, path "\\Reactorsi\UnitAi": - The CFC and SFC charts in all AS projects (PRO_AS) in path "\\Reactorsi\UnitAi" are identified. - The charts that are located one level lower are also identified (e.g., "Drain", "HeatCont", etc.). - A search is also made in the identified charts for blocks that can be monitored by the OS. If some exist, the search will first try to find the template picture of the OS with the name "@PCS7Typicals.PDL" as well as "@PCS7TypicalsXYZ.PDL", and if not (yet) available, the original picture "@@PCS7Typicals.PDL" is taken instead. A suitable block icon is copied from this picture and inserted in the "UnitA" picture. The icon is pre-wired, and only needs to be correctly positioned manually in the Graphics Designer. If "Object name…TAG" = "Block" you specify that only the block name is to be displayed in the picture as an icon heading. The TAG to be displayed may be too long for the other versions. Remark

SITRAIN Training for Automation and Drives
The OS configuration consists of the following three steps. In the first step, the OS is opened for the first time and changed to a single station system or multi-station system. The OS Project Editor enables the configuration engineer to define the basic setting with picture structure and message system. Following setup/checking of the AS-OS connection, the OS is compiled, and the block icons matching the utilized blocks are automatically inserted.
Process screens
The geometry of the process pictures is adapted to the selected resolution in the next block, and the actual process representations are configured as static and dynamic picture components. The Picture Tree Manager is always called during OS compilation, and the AS's PH is incorporated in the overview area of the OS pictures. If additional icons are to be inserted or deleted manually, it may be necessary to manually call the Picture Tree Manager, make the necessary adjustments, and then compile.
Alarm/Tag Logging
In Tag Logging, measured value archives are set up so that in addition to online variables, a history of the measured values (within certain time boundaries) is displayed in the trend pictures of the faceplates. If runtime is activated, the operator can set up and compile online trends.
Lifebeat monitoring
This function monitors all automation systems and operator stations in the process control system for functional competence. You set up and activate lifebeat monitoring in the "Lifebeat Monitoring" editor.
User Administration
User administration is set up to administer and handle different users and their corresponding rights. When this editor is first launched, some rights are set by default and are known for the PCS 7 standard faceplates. You then transfer these rights to individual users when they are set up and organized in user groups.

Multi-station system
A multi-station system is an OS server project with clients (terminals for operators or other servers that obtain data from the first server) assigned to it.
Single station system
The single station system can be used both as an ES and OS. Because an integrated configured operator station is created as a multi-station system, it is necessary to change the OS project to "Single station system". If you right-click the project header in the left navigation window, the project properties dialog box can be called using the displayed context menu (see 1.) The current project type is displayed in the "General" tab. It can be changed here to "Single station system".
PC Properties
Training Center for Automation and Drives
Right-click "Computer" in the navigation window to display the properties of the configured computer. With V6 and higher, the OS projects are distributed such that one or more SIMATIC PCs with multi-station projects are set up for the server OSs in SIMATIC Manager and additional further SIMATIC PCs with client projects are inserted. Check the runtime components in the "Startup" tab, and activate or deactivate them as required. These changes only become effective the next time runtime is started. In PCS 7, these settings are normally made automatically by the project editor and other process control options.

These settings are intended for the post-commissioning phase in order to the OS computer from unauthorized access. Any selected key combinations remain disabled in runtime.
Runtime language
This is the language used (when multiple languages are configured) for the runtime displays. Default runtime language If not all texts are available in the first language, the default language is used for the missing texts. Time-of-Day Setting There are two possible settings for the time type method used in the automation systems: The PLC is set to coordinated universal time (UTC) (preferred setting) (corresponds to GMT ) PLC is set to the local winter time all year (WinCC V5 compatibility mode) Here WinCC is informed which time base the PLC is operating with and how the time stamp is to be interpreted, e.g. in message frames. Settings must be coordinated with the hardware configuration of the AS (CPU and Ethernet CP). Time base
The time base for the time-of-day display in runtime can be set to one of the following three options: Local time zone (local time of the computer) Time zone of the server (migrated project) and Coordinated universal time (UTC) - corresponds to GMT - for display in WinCC Alarm Control and in WinCC Trend /Table Control. The date and time displayed in the top right corner of the screen is always the local time of the computer.

SITRAIN Training for Automation and Drives
The default settings are based on the message design for versions up to PCS 7 V6.0, with the corresponding message windows.
Group display hierarchy (as of V6.1) The setting for the group display hierarchy has important implications. The graphic message system is automatically configured when you select this option. However, in doing so, manually configured group displays may be deleted. Therefore, you have to acknowledge a warning box before the option becomes enabled. This is recommended for new projects. Smart alarm hiding (V7.0 and higher) Here you can offer an additional button for operators in the message window that the operator can use to suppress messages on the display. The messages defined by the operator are not blocked at the source (AS) but are still sent to the OS. They are entered there directly into the history without being displayed. The suppression operation can be time-limited so that messages are displayed again once the specified amount of time has expired. Operator messages

SITRAIN Training for Automation and Drives
OS-relevant data are stored partially in the (sub)project and partially in the OS database. During configuration on the ES, the process information (tags) required in the OS can be scanned directly from the project database. The PH assists you by giving you a structural overview. If the connection exists but the OS has not yet been compiled, the associated process tag (block parameter) can be linked from the ES view, and the "Delta compilation for the tags of the block is performed in the background.
Compile OS
Training Center for Automation and Drives
Because the OSs are not ordinarily used in the system as an ES as well, they require their own database at runtime. Therefore, the OS must be compiled before the OS is activated. This expands the OS database to include the process connections to the ASs, the picture hierarchy (derived from the plant view), the messages from messagecapable blocks and tags that are retrieved only from the OS database during runtime.

If the ES and OS are installed on different PCs, the OS can also be simulated locally on the ES in order to make a preliminary check of the OS's operability and outward appearance. The OS configuration is then copied to a temporary directory on the ES and runtime activated there. If the communication data are exactly the same (the connection name from the ES to the AS is identical to the connection name from the OS to the same AS), it is also possible to establish connection to the AS. Otherwise, fields that are directly linked to variables are "grayed out" to show that there is no process connection. The call is started on the ES in the SIMATIC Manager. Select the OS object to be tested, right-click and select Start OS Simulation to display the same picture as on the future OS. If the test was successful, this OS project can be compiled and uploaded to the physical OS. Provided you have not made any illegal changes, you can load the modified and tested project onto the OS during runtime without interrupting the monitoring.

We shall now look at the fundamental concepts behind creating pictures and how to set dynamic displays. Then you will be able to apply your knowledge in the exercises. Creating Pictures
The "Graphics Designer" editor is used to create the pictures. You open the Graphics Designer by double-clicking on the picture. You can also open the picture in the plant view or in the Picture Tree Manager, if the OS project is opened in the WinCC Explorer.
Object Palette
This window contains predefined graphical WinCC objects that you can drag to the Designer window, and position and expand as required. The picture objects are vectorial, i.e. they can be moved using the mouse at any time. You can also open a library containing additional predefined objects (user objects or controls). It is also possible to add custom designed elements to the library in the "Project library" or globally for the ES in the "Global library".
Library
The library consists of two parts: "Project library" (empty at project start) and "Global library" (predefined graphics). The Global library contains the so-called HMI library - another useful library with different controls for many different technologies.
General Procedure
1. Select the object by clicking it in the palette. 2. In the picture, click the required position, keep the left mouse button depressed and draw a frame around the object. 3. Select the required property from the "Properties" dialog screen (light bulb icon) then right-click to display the context menu and select the type of action you wish to apply. If necessary switch to the "Events" tab and create the required action there via the selected event (lightning icon).

Configuring Objects You can highlight each object on the screen. Right-click and select Properties to open a dialog box where you can modify Properties and/or Events for these objects either statically or dynamically. Properties
The properties are arranged appropriately. For example, a rectangle under "Geometry": has the properties "Height", "Width" (in pixels) or "Colors": "Background color", "Foreground color" etc.
Static
With a property has a static setting, you can select it, then right-click and select Edit
Dynamization
to change the setting.
Here right-click and select Tag or Dynamic Dialog or C Action or VBS Action to associate a different dynamic property with the respective property.
Tag
You select a tag from tag management, if the format of this tag is appropriate for this property.
Dynamic Dialog
This tool is used if the tag/process information cannot supply the property value directly (e.g. "PV_IN" for bar color). Use the dialog to create a table in which defined property values can be assigned to the various process values of a tag. The associated property value for the current process value is determined during runtime and supplied to the object.
C Action/VBS Action
A "C script" or "VBS script" can be used to evaluate any WinCC information during runtime in order to supply a property value not provided by the standard properties.
Events
Right-click and select C Action or VBS Action or Direct Connection. Each action configured in this way is triggered once when the selected event takes place (such as an object change in the I/O field).

At the start of the project, you stored some empty pictures in the plant hierarchy. In these pictures now adapt the window height to the resolution. -------------------------------------------------------------------------------1. Open Graphics Designer, open picture @screen.pdl, obtain picture height of picture window @win12 and enter it here. Picture height:________________ 2. Adapt the picture height of all process pictures from the plant hierarchy (to suit the available equipment) 3. Save the modified pictures -------------------------------------------------------------------------------In the WinCC Explorer, open the Graphics Designer by double-clicking the picture @screen.pdl. Click the middle picture and then right-click and select Properties to open the Object properties for the picture window @win12. If you cannot find the picture window, it may be hidden by other window. Click on any object, open its Properties screen and select the object "@win12" from the dropdown list in the top right-hand corner. The Properties screen now refers to the "@win12" object! In the Object Properties dialog box, select the geometry. The box on the right will show the value for Window Height - enter it under "Steps" point 1. Then open the other process pictures and change the "Picture Height" property to a value that is compatible with your monitor resolution. To do this, go to the property Picture Height --> double-click and enter the change value, then press OK to confirm. If picture adaptation is not carried out, you will be able to select the process picture in runtime, but scroll bars will appear at the right edge of the picture to scroll the process picture in the picture window. A more efficient procedure (for the complete project) would be to modify the first picture in the PH at the beginning and to duplicate it (as an empty picture) in the PH.

The color values are compiled from a large palette, where the 16 basic colors are set using hexadecimal values. You can find the codes in the online help under the search term "Color table". The symbolic constants are externally predefined by #define and provided by WinCC for C scripts. Because the desired color is not achieved by directly assigning a color property to a variable, you need to use the Dynamic dialog here or work in scripts using the symbolic color names in the above table.

Call Faceplate with Mouse-Click Due to the size of the faceplate display, you may often want to display a representative icon and display the faceplate only when needed. - Select the graphical element to be used for making the faceplate visible. - In the Dynamic Wizard -> Picture Functions tab, double-click Picture selection via process tag - In the subsequently displayed dialog boxes, select the block you want. This programs a call of the block faceplate for the selected icon. If the icon's design complies with the guidelines for the faceplate designer (e.g. the standard icons from picture "@Template-PDL") the wizard will also connect the process tag (and all required tags) and make the faceplate visible. Note
It is advisable to choose Group Display as the display type (corresponds to faceplate) - see wide arrow in the bottom right corner of the picture. You can call up the loop display as needed from the group display (complete screen with all available block parameters). To enable integration of these block icons (typicals) in your pictures, the OS project directory \GraCS\ directory contains the @Template.PDLfile It contains the standard typicals for the blocks of the technological library; you can copy/paste them into your process picture. Connection to the process tag is via the wizard (see above). Do not use the icons from "@@PCS7Typicals.PDL", they are intended for automatic generation during OS compilation.

Direct Connection
This form of dynamization can only be used for events present on the triggering object. It is possible to define which source information is to be transported to which destination in a dialog box.
Example
In the above picture, two text boxes and a circle are present. With a mouse click (event) on text box 1 (contents "Visible"), the property "Display" of the circle object will be set (value TRUE). By clicking the second text box, the circle object will be made invisible. 1. Select the triggering object (text box 1 in this case). 2. Open the properties dialog
"Events" tab
3. Next to the lightning icon for the "Mouse click" event, right-click and select "Direct connection". In the dialog that appears next, you can select (or enter in the case of constants): - the source and the type of information (constant, property of which object, tag) - destination (properties of the current window, properties of an object in the picture, a variable from the tag management) Data that are to be transferred. In the example, select the constant on the left as the source (enter the Boolean value TRUE). As the destination on the right, select the circle object "Circle 1" and then the property "Display" referring to this object. When you click OK, a blue lightning icon at the source ("Text box 1", event "Mouse click") indicates an outgoing direct connection. In the destination object "Circle 1", the destination property "Display" is shown in italics (Display) as reference to an incoming direct connection. 4. To switch the circle to invisible, repeat the process starting with the second text box (content "Invisible")

The group display (1) preconfigured in the area overview combines messages from group displays (2) and (6) from the area picture ("Reac.pdl") From V6.1 they can be automatically generated (setting in OS project editor, Message Display tab). Although their default setting is hidden (invisible), they can be post-edited in the pictures. "Reactors" Area PictureThe group displays in "Reactors.PDL" combine the messages from the group displays (3) and (5) from the pictures "UnitB.PDL" and "UnitA.PDL". The group display (4) combines messages from "UnitB.PDL" (3) and group display (6) from picture "UnitA.PDL" (5). "UnitA" Detail Picture“ This contains group displays that are assigned to the measurement point. These are either complete PCS 7 block symbols (with integrated group display) or group displays that have been inserted by the use and are linked to the process tag by the Dynamic Wizard (see also next page). Chaining If a measurement point triggers an alarm, this event is collected (ORed) via the group displays of the higher-level pictures and displayed in the area overview (even if the signaling process tag is not in the picture currently being displayed). As the area overview picture is always visible at runtime, the plant operator can immediately determine if there is a disturbance in one of the plant areas. Selecting the Trigger With the configured "Picture selection via group display" you can click on the alarm/warning signal to track the collect path - but only if the message is present. Note If you make changes to a picture regarding group displays (inserting, editing or deleting group displays/blocks with group display), you must call up the Picture Tree Manager and save the hierarchical group display with the option "Calculate the group display hierarchy completely new again while saving" activated: via Project -> Save When the OS is compiled, this procedure is automatically carried out.

Info
This type of connection was used in previous versions of PCS 7 because readyto-use block icons were not yet available (see "@@PCS7Typicals.PDL"). This procedure is no longer necessary in the current version when using the ready-touse icons. Also the appearance, number and message class assignment of the fields in the group display can now be changed. Connecting the Group Display to a Process Tag If you need to recognize the alarm/fault state of a process tag in a picture (provided that this process tag provides this information), you can use a group display and connect it to the special "EventState" tag of the associated block. This tag is only available in the tag management of the WinCC Data Manager after the OS is compiled. The easiest way to establish this connection is using the Dynamic Wizard. - Select group display - In the Dynamic Wizard -> Standard Dynamics tab, double-click Connecting the Group Display to a Tag Structure. - Select the block name and the instance and confirm your selection.
Note
Training Center for Automation and Drives
If you make changes to a picture involving group displays (inserting, editing or deleting group displays/blocks with group displays),you must call up the Picture Tree Manager and, with selected option, "Calculate the group display hierarchy completely new again while saving" explicitly save via Project -> Save to complete the operation. When the OS is compiled, this procedure is automatically carried out.

Exercise 1
In order to display alarms immediately in the overview area of the OS, group displays are needed as links between the process pictures and the overview area. These group displays collect and pass on messages from and to the lower-level pictures as defined in the Picture Tree. These group displays are connected to the lower-level pictures. After OS compilation, verify that your OS project editor settings have taken effect. (i is your group number) --------------------------------------------------------------------------------
Steps
1. Open the Picture Tree Manager and activate the "Preview" view. 2. Check whether you can see a group display in the "Reactors" picture and the block icons in the "Unit A" picture. 3. Open the Reactors picture in Graphics Designer and check the group display (Properties and Events)
Action
1. Open the Picture Tree Manager and switch the view to "Preview".
-------------------------------------------------------------------------------2. Verify that a group display or block icons can be recognized in the right preview window by selecting the "Reactors" and "UnitAi" pictures. If not, check the settings in the plant hierarchy for the OS compilation and, if necessary, in the "Message display" tab in the OS project editor. The icons should appear there when you repeat the OS compilation. 3. The group display must be present in the "Reactorsi" picture and the "Group Value" property and the "Mouse Action" event must be completely configured. The "Display" property is preset to No. You can change this setting. Position the group display (if it is to be displayed) at the required location. Note
Training Center for Automation and Drives
Each time you change a picture involving the group displays, it is necessary to recalculate the group display hierarchy by saving again (explicit SAVE operation in the Picture Tree Manager!), unless you are subsequently going to compile the OS.

Set up two users (e.g. "First" and "Second") in the User Administrator. Give these users the authorizations illustrated in the slide above. -----------------------------------------------------------------------------In the WinCC Explorer, select "User Administrator". Right-click and select Open to activate it.
Group
Set up a user group (e.g. Plant operators) Right-click and select Create group Assign all rights to this group that are common to all plant operators (serves as a template). Double-click the white/red fields in the "Authorization" column or in the areas.
User
Select the Plant operators group. Right-click and select Create user
and the option: Copy group settings also
to create the new users. Provide the new users with a name (Login) >= 4 characters and password >= 6 characters. Assign rights by modifying the rights associated with the group. For our exercise, use passwords like aaaaaa for all users, so that they are easier to remember! Note The user administration authorization makes it possible to call up the "User Administrator" during runtime and set up new users, as well as change or delete existing rights for existing users! This authorization does not include operator control and monitoring. If you want to assign this function to your user, it is necessary to activate additional authorizations, such as 2, 4, 5, etc. However, the user with user administration authorization can call the "User Administrator" during runtime and activate additional authorizations for themselves. After you log on again, the new authorizations are active!

SITRAIN Training for Automation and Drives
If the SIMATIC Logon option is installed on the computer, the users must be set up in the Windows computer management. Further groups are automatically installed there in addition to the existing user groups (e.g. users, administrators, power users) through installation of the PCS 7 components (e.g. SIMATIC HMI through WinCC, Logon_Administrator through SIMATIC Logon). If the WinCC user administration is then to interact with SIMATIC Logon, separate user groups must first be created under Windows (e.g. "Plant operators", "Maintenance" etc.). The Windows users are also created there, and assigned to the respective group. The "SIMATIC Logon" option is selected in the User Administrator tool (see slide) in WinCC. Then you insert the groups, which must have the same name as the Windows groups ("Plant operators", "Maintenance" etc.), and assign the WinCC authorizations to the groups. No users are inserted in WinCC! (You have already set them up in user groups of the same names in the Windows computer administration.)
Remark
In addition to being a member of his own group, the WinCC user must also be a member of the "SIMATIC HMI" user group.
Runtime
If WinCC is used in runtime, a new screen form is offered for logging-in (see slide) in which the Windows login (e.g. "FIRST") is typed. If the login and the password agree, the logged-in user has all authorizations of the user group with the same name from the WinCC user administrator. As a Windows user, you can change your own password yourself (if allowed in Windows). If you call the user administrator during runtime, the active login appears underneath the associated group.

Online Trends
Date: 12.12.2006 File:ST-PCS7SYS_V70B&B.61
SITRAIN Training for Automation and Drives
During controller commissioning, it is very helpful to be able to graphically evaluate aspects such as the oscillating behavior of the closed-loop controller. For this purpose, the operator can create a trend group online during runtime. The tags can be supplied directly from the data manager of the WinCC Server or from the Tag Logging archives.
Advantage
The operator can check the time sequence of any analog or binary process signals at any time, regardless of the configuration. Note that when you display the online values directly from the data manager, a new trend display will be started each time you call a picture (as there is no history).

Enter a meaningful name for this trend group and select 'Online'. A properties dialog box is displayed; use the "+" button to select the required number of trends, change their names to representative names, and click the 'Selection' button to assign the required process tag. After you confirm your selection, the trend window is immediately displayed modally, regardless of which area picture is currently displayed. The operator can change the group composition at any time.
Remark
Training Center for Automation and Drives
In the trend group, it is also possible to access tags from the archives. Thus, it is also possible to compare a current trend with an archived trend.

PCS 7 Message System The message system is represented in the OS by means of alarm controls. This display is accessed by activating the "Message system" key in the first system key set. A specific key set is then displayed (see above), via which you can open the various message windows. There are two different message system types for the OS - Bit message procedure (not in PCS7) and - Chronological reporting in which the messages are generated within the driver blocks and technological blocks of the AS and are sent to the OS as message frames (telegrams) with time stamp. The messages are then entered in the short-term archive. To ensure that these messages are not lost, the archives are saved in a backup as specified in the configuration. The messages and the complete message system were generated from the standard blocks of the technological library during OS compilation in the form of system messages for the AS and OS. A distinction is made between messages requiring acknowledgment and those which do not. Layout of the Message Line A message is composed of different information components, which are created in groups as system message blocks, user text blocks and process value blocks. The system message blocks contain information such as the date and time, as well as message classes, message types, message state and duration. The user text blocks contain information such as the message event, message origin, and area. The process value blocks also provide up to 10 process values for the messages if required and configured.

SITRAIN Training for Automation and Drives
The message system can be viewed and adapted via the Alarm Logging Editor in the WinCC Explorer, if this has not yet been done via the OS Project Editor. When the OS Project Editor is run, the settings in the Alarm Logging Editor can be affected. Alarm Logging is divided into three windows (panes), - The navigation window containing the Message blocks, Message classes, Group messages, and Archive configuration - The Edit window showing details or components of the topic selected in the Navigation window, and - The table window containing the individual messages. This window lists the already configured messages, and also allows new message to be added for the bit message procedure. Classes and Types
In alarm logging, all messages can be assigned to one of the up to 16 message classes. Among other things, the message class determines the acknowledgement procedure for the class and identifies the message status "Came In", "Went Out", "Acknowledged" and "Came In and Went Out". Up to 16 message types can be created for each message and define the coloring of the message states "Came In", "Went Out" and "Acknowledged" for each type.
Note
The PCS 7 standard is the initial template for the message system. The template file "MessageTemplate.cfg" can be found in "Installation_directory\Options\SSM". If you do not wish to use the PCS 7 standard, you can use this configuration file as an example for your own, individual configuration file. Prior to conversion, save the "MessageTemplate.cfg" file under a different name outside the installation directory (see online help in the Project Editor).

Archiving
Date: 12.12.2006 File:ST-PCS7SYS_V70B&B.65
SITRAIN Training for Automation and Drives
Depending on the message class, changes that occur in message states are written to configurable archives. Archiving takes place in the message archive. For this purpose, various parameters such as the archive size, time range, switchover time, etc., are set. If one of the configured criteria is exceeded, the oldest messages in the archive are overwritten. The backup of the archiving databases can be specified through additional settings. Display of messages saved in a message archive takes place in a long-term archive list or a short-term archive list. Display of messages in the short-term archive list is updated immediately upon receipt of a new incoming message. Details on the archive settings and on the backup are discussed with the topic "Tag Logging", since the procedure is based on the same principle.

Disable messages through OS operation Area-based
1. With the area selected, change to the second system key set and press the disable icon. Any pending messages in group displays will be reset and replaced by a white "X"; current messages will be displayed in the history as disabled. 2. With the area selected, press the enable icon. The area is enabled again. Any individually disabled tags in the area are also enabled! If the causes of messages are still present at this time, the status changes, but the messages are displayed as acknowledged messages with the time stamp crossed out (as occurs with an OS startup).
Tag-based
1. With the faceplate selected, press the disable icon in the faceplate. The messages of this tag are entered as acknowledged and disabled. The group display is replaced in the faceplate by a white "X". 2. With the faceplate selected, press the enable icon in the faceplate. Only the messages of this tag are enabled. The response in the history is the same as with the area-oriented enable (but only for this tag).
Alarm-based
Individual limit alarms can be suppressed in the faceplate, typically in the limit view.
Disable messages through process statuses An input parameter MSG_LOCK exists for the PCS 7 blocks with message capability. If this is set, the process alarms of this block are disabled (upper/lower alarm, upper/lower warning). Process control messages triggered by the CSF parameter (typically channel faults of the driver blocks belonging to the tag) are still signaled. This is relevant when starting-up/shutting-down the plant if the process variables monitored are outside the operating range.

Alarm Hiding
The operator can also hide selected messages. When messages are disabled, a message is not generated at the source despite an event. When messages are hidden, the message is no longer displayed for a preset amount of time, but it is entered in the history/archive. It can also be switched over manually to "Display" later.
Action
In the message window (e.g. new list, see above) 1. Click scroll icon 2. Select message to be suppressed 3. Click high/show message icon.
Result
The Hide operation is logged in the operating list. The message "hidden" in the above process is acknowledged internally and no longer displayed. If it exits and comes back again, it is acknowledged and entered into the history or archive, but it is no longer displayed as an alarm line or in the new list. It remains hidden (in the "normal" message windows) until it is shown again by the same operating sequence in a different alarm window (see below). It is also shown again automatically when the time set in the Project Editor expires (see slide)
Information

Automatic alarm hiding (principle) 1. In Global declarations Project enumerations, an "Operating State" list is set up containing possible operating states for a plant (e.g. start-up, maintenance, emergency stop etc., max. 32 statuses) and associated INT values. 2. Plant or plant section blocks with message capability (MOTOR, VALVE, etc) are combined into a so-called block group ( e.g. in the CFC Object properties of block Block group) by entering same name there. 3. A STATEREP block is configured for each group (with same block group). Using XOR logic, one of the 32 inputs of this block is set, corresponding to the current plant status. The STATEREP passes this information on to the OS via the QSTATE output. The attributes of the STATEREP block mean that this block is handled in a special manner in the OS. 4. In the process object view of the AS project, a status matrix is offered in the "Messages" tab (scroll to right). For blocks with entered block groups, the plant status (column) in which this message is to be hidden can be selected here for each type of message (line). Although the messages are generated by the AS during runtime, they are hidden in the respective status of the plant and handled the same as with manual alarm hiding (see previous pages).

SITRAIN Training for Automation and Drives
The project directory of the OS contains a file (master database) for management of the runtime data; the name of this file consists of the project name followed by RT and the file name extension .mdf, here, e.g. OS01RT.mdf. This file contains the references to the runtime databases. The databases are created with MS SQL Server 2005. All archives function as cyclic archives! The runtime data are stored in so-called segments, for which the configuring engineer specifies a max. content or a date/time for changing to the next segment. If the configured content limit is reached or the configured time duration is exceeded, Alarm Logging or Tag Logging starts new segments in the respective database. When the maximum total segment size is reached, the last segment is exited and archiving starts again in the first one, overwriting the "old" runtime data. To avoid loss of data, the configuring engineer can enter a network drive directory and substitute drive directory for the backup function. Tag Logging distinguishes between two types of runtime archives. TagLoggingFast is used for archive data that are stored in archiving cycles 1 minute . These represent different archives in different directories on the hard disk. You can change the default setting of one minute via Archive Configuration TagLoggingFast Archive Content Tag Logging tab. Messages are also saved here in an archive. There is a "Long-term archive" view where ActiveX displays in the history window only those archived messages that already existed when the message window was called. This is the default history setting in PCS 7. There is also a "Short-term archive" view that is updated when messages arrive. This view can be restored after recovery from a power failure (selectable via Alarm Logging Archive Configuration Message Archive right click and select Reload …)

CS Database
The OS project directory contains a configuration database for the configuration data (message texts, connections and tag definitions, Alarm Logging and Tag Logging); the name of this database consists of the project name followed by the file extension .mdf, e.g. OS01.mdf. There are two addition files: e.g. OS01Tlg.mdf for configuration data of Tag Logging and e.g. OS01Alg.mdf for Alarm Logging. The files with the same name and the endings .ldf are log files where the SQL server records the accesses/changes to the database.
Directories/Names
The master database, here OS07RT.mdf, is located in the project path of the OS project. The runtime archives - divided into Tag Logging and Alarm Logging - are located in a subdirectory \ArchiveManager. The AlarmLogging subdirectory contains the message archives of the long-term archive; the file name consists of: __ALG_YYYYMMDDhhmm.mdf or __ALG_StartTimestamp_EndTimestamp.mdf e.g.: LNB04_OS07_ALG_200504260901_200504260949.mdf These files with two time stamps contain the message data of the corresponding archive segments. The \TagLoggingFast directory contains the runtime archives of measured values with an archiving cycle 1 minute are contained in the runtime archives in the \TagLoggingSlow directory. The name of the archive files is composed of __TLG_S_YYYYMMDDhhmm.mdf - the "S" stands for TagLoggingSlow.

to select the archiving method. The "Archiving" and "Long-Term Archiving" options differ only if your project uses a Central Archive Server (CAS). In that case, the archiving options differ according to the OS properties for the CAS that you specified in SIMATIC Manager (see next page). The connections marked as being relevant for archiving are created as archive tags in the OS project during OS compilation and a process value archive is created if it does not yet exist. If a connection that is included in the archive is subsequently deleted or marked "No Archiving", the corresponding archive tag is deleted the next time the OS is compiled.

SITRAIN Training for Automation and Drives
CAS Principle of Operation The respective OS master server transfers completed archive segments (see previous page) as a copy and OS reports into the enabled input path (share) on the CAS. Transfer of SIMATIC Batch reports logs is triggered from the start center. The cyclic archive continues on the OS server. Midterm Archive
The StoragePlus software integrated on the CAS continues to run there. It resolves the incoming data, and saves them in a separate database whose structure as a cyclic archive corresponds to that of the OS (WinCC) server. Segments of this cyclic archive are adapted depending on the size of the selected long-term memory medium, and they permit data to be swapped out to a backup after switching to a new segment.
Client Access
Every client can access both the assigned OS server and the central archive server (CAS). The client possesses one package from each assigned OS server and the CAS. Access is transparent for the operator Depending on the time period for displaying data, the client obtains the data from the OS server or, if they are no longer present there, from the CAS. The client can no longer access data which have been swapped out from the CAS to the long-term archive. To achieve this, it is necessary to insert the long-term memory medium and to connect this to the database of the CAS (using the StoragePlus administration console on the CAS).

If the "Transfer to Central Archive Server" option has been set for the OS (see previous slide), the option "Only long-term data" can be set for the CAS. If this option is set for the CS, only the block parameters with the setting "Long-term archiving" will be saved here. If the "Only long-term data" option is not set, all Tag Logging parameters on the CAS will be saved. The distinction is irrelevant for message archives.

Archive Configuration Upon selection of the Archive configuration icon in Tag Logging, a selection of two archive types is displayed. - TagLoggingFast is for recording archive values that are archived in cycles shorter than 1 minute - TagLoggingSlow is for recording archive values that are archived in cycles longer than 1 minute. Note
You can change the default setting of one minute via Tag Logging tab.
Archive Configuration
TagLoggingFast
Archive Content
Each of these archives is subdivided into segments and are configured by doubleclicking on TagLoggingFast or TagLoggingSlow. These segments determine which storage space is to be reserved on the hard disk - e.g. 1 day and 44 MB. If one the two limit values is exceeded, i.e. either the time duration of 1 day is exceeded or the storage space of 44 MB is reached, then Tag Logging automatically records in the next segment. Using the same method as for the segments, the configuring engineer also specifies a total time duration and total storage capacity for all segments. If one of these values is reached, the oldest segment is overwritten. This means that cyclic archiving is used here too. Backup
Training Center for Automation and Drives
The configuring engineer also specifies whether and when the archive is to be transferred to a specified network drive as a "Backup".

SITRAIN Training for Automation and Drives
In this series of exercises you will create/configure a process value archive in Tag Logging and then use this archive to create online trends. We shall compare using these process value archives and using trend screens from the controller faceplate. After completion of all activities and tests, the multiproject is to be archived. ----------------------------------------------------------------------------------------------------------
Exercise 1
In the process object view of the AS project, set the parameters SP, PV_IN and LMN of Unit A's temperature controller to archivable (long-term archive). Compile the OS and check the resulting Tag Logging archive "SystemArchive". ----------------------------------------------------------------------------------------------------------
Procedure
Open the CFC with the temperature controller for Unit A. Set long-term archiving for the above mentioned parameters (in the Properties screen of the respective parameter). Open the process object view for the multiproject, select the AS project and open the "Process Value Archive" tab sheet. You can check or modify the option "Long-term archiving" for the two parameters (see also slide 67). Compile the OS. In Tag Logging check the archive called "SystemArchive". Change the acquisition cycle there and then check the process object view.

Archiving
Archiving a project means creating a compressed file from many files and directories - usually as a ZIP file. The SIMATIC Manager provides an integrated interface for ZIP archives. You can also use "PKZIP for Windows", an additional compression tool which is included on the installation DVD, for archiving and dearchiving.
Preparation
Exit all SIMATIC Tools such as HW Config, CFC Chart, SFC Chart or WinCC - as well as CS and RT. The SIMATIC Manager is the only program open - and it is advisable to close the multiproject there too. In addition, all other ESs that have open subprojects belonging to our multiproject must close them too. If you forget to do this, archiving fails and terminates with an error message. In the SIMATIC Manager, select File Archive In the first dialog box, select the required multiproject Color. Acknowledge your selection and then specify the target location and archive name in the next dialog box; the name should not exceed 8 characters and is followed by the file extension . ZIP

Time synchronization Process data can be evaluated if all components of the process control system work with an identical time of day. This guarantees that messages can be assigned in the correct chronological order irrespective of the time zone in which they occur. Active time master So that all operator stations and automation systems on the plant bus and on the terminal bus have an identical time of day, one OS server, for example, assumes the function of the time master from which all other systems receive their time. The acceptance or failure of the "Time mastership" is indicated by process control messages. Passive time master The other OSs can also be configured as time masters, but they are initially synchronized like a slave (as a passive time master). If the active time master fails, a passive time master takes over the task, and becomes the active time master. Time slave
An OS client obtains its time-of-day message frames from one of its OS servers (via the terminal bus). An AS obtains the time of day from the active time master (via the plant bus)

OS time of day
WinCC Explorer contains the LT option "Time synchronization".
OS server
After selecting this option, you typically select synchronization via the plant bus for the OS server. In so doing, you select the access point (link to the interface parameter assignment) via which the ISO protocol is routed to the plant bus. You also set the role there (typically "Master"). The master then becomes active or passive during runtime, depending on the case. The slave setting is useful if the time signal receiver determines the time of day (e.g. SICLOCK).
OS client
In this type of project, only synchronization via the terminal bus is offered. The time of day is typically received from a connected server, which has been assigned to the client (i.e. the client has downloaded the server package).
Computer startup list
When time-of-day synchronization is activated, the "CCTMTimeSync.EXE" program is included in the startup list and is launched each time runtime is activated. If the WinCC project is not in "Runtime", the computer is not synchronized.

The symbolic names of the access points can then be chosen if the ES and OS communicate on the plant bus through different hardware. During OS configuration on the ES, the only interface parameters you can assign in the "Time Synchronization" editor are those that are present on the ES computer.
Procedure
If you change over to symbolic names (see slide), select a name for the access point. Use the access "" if you are using BCE communication, or use if the SIMATIC CP 1613 is used. You determine the underlying hardware and interface parameter assignment on the OS target computer (the same computer in your case). From the Windows task bar, select START

The report system offers the possibility to create so-called feedback documentation of the OS project in the CS configuration mode. A range of online value reports and archive value reports are available in runtime mode. Of course, only those messages that meet the configured criteria are printed out.
Layout Editors
The report system provides two powerful layout editors under Layout 1. Page layout editor for report printouts on page printers (e.g. laser printers or graphic inkjet printers) that print whole pages at a time and 2. Line layout editor for report printouts on line printers (matrix printers), which are mainly used for the message sequence report. Incoming and outgoing messages are printed in the message sequence report, together with their status and respective time stamp. A default layout is supplied and can be customized @CCAlgRtSequence.RP1 The line printer works with continuous paper and prints one line at a time, when triggered by a message. The prepared print job @Report Alarm Logging RT Message sequence is available for this. If you display print jobs in the right-hand window of WinCC Explorer, this print job is indicated by a yellow symbol. In contrast, page printers "collect" messages until a complete page can be printed. Then the print operation is triggered. Any job can be created for the page printer.

Printing out reports for project documentation (back documentation) via the configuration software is generally performed by the operator. You initiate printouts of reports for the runtime documentation via "print jobs". A print job determines: - Whether and at what time a report is to be printed - Which layout is to be used for printing - On which printer or to which file is to be printed Reports can be output in the following ways: - Time-controlled – e.g. every hour, daily or at change of shift - Event-controlled – e.g. when certain limit values are exceeded - Upon change – e.g. after a key is pressed by the operator Activate the Report Designer --> Print Jobs menu to select the existing print job @Report Alarm Logging RT Message sequence Right-click and select Properties from the context menu to open it. In the print job you can specify which print layout and which report type is to be processed. The default setting is Line layout. Uncheck the checkbox and select layout @alrtmef.rpl for the message sequence report. Printer Selection
In the "Printer Setup" you set whether you want to use the "Standard Printer" only or you can use up to 3 alternative, hierarchically configured printers that you can use for the report printout - depending on their availability first 1.) then 2.) and then 3.). In addition, or as an alternative you can also print to an EMF file, which is then archived or printed later.

Prototyping
A customized object is a group of graphic elements where only the desired properties are taken and made available for additional parameter assignment (Create customized object). In Prototyping these properties are connected with what are called "structure member variables". This presupposes the existence of a structure and at least one structure variable.
Instantiation
The reproduction is followed by a permanent instantiation of these "copies" using a wizard; the wizard links all sub-tags of the selected structure tags "in one stroke".
Ability to Make Changes The prototype only needs to be created once, but can be used an unlimited number of times. If any later changes are to be made that affect all "copies" of this customized object, then they must all be changed individually. It is therefore only worthwhile to use a customized object when you require it for multiple use.

The Assigning parameters dialog box is displayed by double-clicking --> "GetVisible". With double-click --> "lpszObjectName" the desired graphic object is selected here the static text, assigned to the picture Test.PDL. The result is binary, therefore "yes" or "no".
SetVisible
In order to make a graphic object visible or invisible, WinCC provides the internal function "SetVisible". This function can be found under "Internal Functions" --> "Graphics" --> "set" --> "Miscs" --> "SetVisible". Under "lpszObjectName" select the static text assigned to the picture "Test.PDL". "bVisible" is the future state, i.e. to be set by the function "SetVisible" "1" or "True" for visible "0" or "False" for invisible.

In picture Test.PDL create a static text as operator information. This static text is to be switched visible and invisible when a button is activated (right mouse click RMC). As an option, at operation of the static text, the C script can be displayed as a screenshot. ----------------------------------------------------------------------------------------------------------
Steps
1. In the Graphics Designer open the picture Test.PDL and insert a static text and name it "Operator_C_Text". This text is to be statically changed to invisible with the property "visible - no". 2. insert a button in this picture. In the "Properties" dialog box in the "Events" tab, create a C action which it to alternate between making the static text visible/invisible. 3. Save this picture and change in runtime in the process picture "Test", to test the function. Optional 4. In the C Editor in the Graphics Designer create a screenshot of your C script and insert it in the picture "Test.PDL" as "OLE object". In the Properties dialog box, set the property "visible" --> no. 5. Create a mouse action on the static text to make the C script visible. With the mouse action of the button, this script is also to become invisible if the static text is switched to invisible.

WinCC offers the possibility of creating properties in addition to the standard ones, and, in particular, supports creation of actions by means of VB scripts. Like C scripts, the VB scripts are interpreted and processed during runtime. As an example, we have also used here hiding and showing a static text. The static text has the static property "Visible - no". The VB Editor can be started via a button Properties dialog --> Events tab, right-click --> "VBS Action...". In order for the object state of e.g. our static text to be queried, a pointer must be placed on this object. This pointer is assigned to an internal variable - created using a DIM statement. First the status of the "Visible" property must be queried.. If the static text is visible, it must be made invisible. If however, the static text is invisible, clicking the button is to make the text visible.

In order to create the property of a graphic object in VBS, you need to place a pointer to this object via a "SET" statement and assign this pointer to an internal VB variable. The VBS action is started by selecting the button then right-click --> "VBS Action...". The DIM statement is created as an internal variable of type "Variant", which can transfer the pointer to the object using the "SET" statement. The keyword "ScreenItems" is then used and the object name enclosed in "quotation marks". The required object property can then be accessed by addressing the internal pointer variable followed by a period and the property name e.g. "TextObjekt.Visible".

Maintenance Station An OS (an OS area) can also be configured and used as a Maintenance Station (MS). Using the MS it is possible to call information on the status of all PCS 7 components in hierarchically structured diagnostics displays. An MS can also be configured in a client/server architecture. The MS server is an OS server, whereas the MS client runs on an ES. For diagnostics purposes, the MS accesses data resulting from the use of driver blocks (driver concept) as well as further information produced by SIMATIC PDM, OPC and other software components. Operating principle
Diagnostic event is displayed, and triggers a message or horn. Operator requests maintenance, with automatic documentation (with device and diagnostics data). Maintenance department obtains information, sets processing status to "In progress" (to avoid a double job) and carries out the maintenance. The end of the maintenance work is set as a status, and documented. Through successive setting of the maintenance status, the current status/maintenance needs are displayed. Optional printing of statuses and requirements allows simple recording of jobs for the maintenance team.

Your project is completed. Now extend it by adding the functionality of the Maintenance Station. ---------------------------------------------------------------------------------------------------------
Steps
1. In the plant view, select the multiproject, Settings
right-click and select Plant Hierarchy
and supplement this by the option "Derive diagnostics displays from PH". Select the OS which is to be used as an MS (in your case, only the ES/OS is present). Following acknowledgment of messages, the PH is expanded in your projects of the multiproject. However, this is only a preparation. Remark
If you use the SIMATIC PDM package and always wish your pictures to display up-to-date information/diagnostics from it, you must additionally select the "Detailed diagnostics" option in the object properties of the OS (on the ES/OS in the case of a single-user system, on the MS client in the case of a multi-user system). 2. In the plant view, select the multiproject again, right-click and select Plant Hierarchy Screens
Create/Update Diagnostics
and wait for the diagnostics information to be generated (see next slide).

Setting of the maintenance status is also logged as an operation. The comment block also contains the comment at the time at which the maintenance status was set.
User Diagnostics Structure (Condition Monitoring) Below the diagnostics area in the PH, the user can create his own diagnostics structure with its own pictures. It is also possible to generate maintenance information for devices that do not supply their own diagnostics information. The ASSETMON block is available for this in the PCS 7 library V7.0. The block is used to monitor three analog process variables for violation of three separate limit values. It signals the maintenance status of the process variables: ·
on violation of a limit or
·
by means of the device-based Quality Code or
·
by means of signal inputs.
Note
The block does not contain any process-related or device-related processing components and is therefore not considered by the driver generator. In order for this monitoring to achieve a similar behavior as the self-diagnostics of "intelligent" devices, this block is configured using SIMATIC PDM. This enables the same maintenance sequence to be performed when a diagnostic event occurs.
