Preface

Conventions Menu Bar Commands This document uses an abbreviated format for menu bar commands. Example

From FoxView, click ScratchPads > group_list. means: Click (or touch if using the touchscreen) ScratchPads in the top menu bar. Move the cursor to group_list, and click (or touch) to select it.

Command and File Name Syntax In commands and directory paths and file names, variables are formatted in italics. Example of command syntax

To add a trend_list to display bar button 18, enter: dmcmd dbar_button 18 “dmcmd sublist $SPAD_DIR/../Trends/trend_sublist.txt” -l “button_label”

where button_label is the name that appears on the button. Example of directory path and file name syntax

When a new trend is assigned to an environment trend_list, one of files is copied into the \opt\customer\ScratchPads\EnvironmentName\Trends directory. The copied file is renamed as trend_button#.fdf, where button# is the number of the button that was assigned to open the trend, and EnvironmentName is the name of the FoxView environment.

1. Introduction to FoxView This chapter introduces FoxView and discusses I/A Series environments and applications, printer setup, configurators, and alarms.

Overview of FoxView FoxView is the I/A Series user interface between you and the process. From FoxView, you can interact with any or all of the real-time plant, field, and process data available in the I/A Series system. FoxView provides:  Entry into user-configurable operating environments specific to each user  Execution of embedded real-time and historical trending  Direct access to dynamic process displays  Access to the four most recently used displays  Service and display of process alarms, using the Alarm Manager  FoxSelect, which in turn, provides an overview of the compounds and blocks in the control database, and access to Block Detail Displays  Access to other applications (if permitted), such as:  System Management  FoxDraw™ software (“FoxDraw”) for building and configuring dynamic user graphics  Integrated Control Configurator for configuring the control database  AIM*Historian for configuring the historization of process data and system messages.  Display Editor (DEdit), Display Converter (DConvert) NOTE

On Solaris 10 workstations, FoxDraw software is not accessible from FoxView software.

1. Introduction to FoxView

I/A Series Hardware Your I/A Series system can include these hardware items:  Fieldbus modules, Fieldbus processors, and power modules  Modular Industrial workstations  Personal workstations  Application workstations  Multi-headed workstations  Pointing devices, including mice, trackballs, or touchscreens  X Terminals  VT100 compatible terminals  Printers  Annunciator keyboards  Data storage devices.

Multi-Headed Workstations An I/A Series workstation can support multiple monitors. This feature, called multi-headed operation, allows a workstation to display up to four times as much information as can be viewed on a single screen. Multi-headed workstations can support:  Four annunciator keyboards  Four annunciator keyboard horns  Two console horns  Two external horns. When configured for multi-headed operation, standard (non-touchscreen) monitors share a single keyboard and pointing device, and the cursor moves from one screen to the other screen.

Solaris Based Workstations Solaris based workstations can be configured for two standard or touchscreen monitors. An application opens on the screen from which it is called. Additional FoxViews can be configured for different window sizes and can call different Alarm Managers.

Windows Based Workstations Windows XP based workstations such as the AW70 can be configured for up to four monitors, and a maximum of two touchscreens. The Windows XP based P92 workstation can be configured for two monitors and two touchscreens. You can open an application on one screen and move it to another screen.

I/A Series Environments An environment is a collection of programs, utilities, and displays grouped according to users and the tasks they perform. Each environment has its own menu bar, menu commands, and display bar (left side of screen). If required, an environment may also include an access password for security, as well as protection levels to disable certain menu options or buttons.

I/A Series Applications System Management System Management is the I/A Series software that monitors the health of your system’s network and hardware. The status of the FoxView System button indicates system health. A changed system status is indicated by this button’s color and blinking. Clicking the System button calls up the System Management application window, permitting you to:  Acknowledge system alarms  Monitor the equipment and communication status at each station  Perform tasks, such as checkpointing the system, updating an EEPROM, or turning equipment on or off.  Diagnostics. For more information about System Management, refer to System Management Displays (B0193JC).

Alarm Manager The I/A Series Alarm Manager provides seven alarm displays for viewing and responding to process alarms. By default, clicking the FoxView Process button calls up the Alarm Manager’s Current Alarms Display, which shows all existing alarm conditions. Alarms are color coded by priority to help you quickly focus on critical conditions. From the Alarm Manager’s Operations display, you can access any of the other Alarm Manager displays. You can use the Alarm Manager’s Find capability to acknowledge and clear specific sets of alarms, and the Match/Filter capability to specify the alarms you want to view based on a time frame (for example, a particular compound or block, or an alarm type). For more information about the Alarm Manager and the alarm displays, refer to the Alarm Manager On-Line Help (am.hlp) or the I/A Series Workstation Alarm Management (B0700AT) document.

Configurators FoxCAE FoxCAE software is an optional engineering package for designing the control database and AIM*Historian database, and producing typical loop drawings. Use FoxCAE to build software loops of control strategies using a tag list and standards such as typicals and default values. Typicals are built with a graphic loop editor, enabling you to view the layout of the loops during the planning stages as well as print out a loop drawing. You can load a database (created using the Integrated Control Configurator) into FoxCAE to generate loop drawings for the database.

DD Explorer DD Explorer, used with FoxCAE, translates H1 device descriptions in device templates that can be imported into FoxCAE, eliminating the need for NI-bus communication. DD Explorer is also used with IACC to provide device-appropriate configuration options for DCI Function blocks used with H1 devices.

IACC IACC offers the following coordination with FoxView:  Quick View is a commissioning tool available for on-platform IACC clients. Quick View automatically generates a FoxView group display with a faceplate for each block in the control strategy diagram (CSD) showing live data from the CP. The faceplates are arranged in the same relative positions as the block in the CSD.  IACC is integrated with the FoxDraw software so you can create FoxView displays by simply dragging block objects from the IACC Project Navigator into the FoxDraw Editor. IACC also supports download of the drawing files to the I/A Series workstations.

FoxDraw FoxDraw is the display builder/configurator used to create and maintain graphic displays for viewing process dynamics. Use FoxDraw drawing tools and graphic object palettes to create process displays representing the plant, a process area, or a portion of the process. Use FoxDraw to connect display objects to process variables and operator picks, providing dynamic updates as a method interacting with the process. Refer to the FoxDraw On-Line Help (foxdraw.hlp) or FoxDraw (B0700BE) for more information.

FoxPanels Configurator Use the optional FoxPanels Configurator to create and configure these types of alarm panels:  Customized alarm panels  Emulated annunciator keyboards (soft alarm panels) 

Hardware annunciator keyboards You can specify panel layout, button appearance, button labels, access to process displays, program, script execution, and the blocks to be monitored. You can also configure workstation horns for both process and system alarms. Refer to the FoxPanels Configurator On-Line Help (foxpancf.hlp), FoxPanels Runtime On-Line Help (foxpanel.hlp), or I/A Series Workstation Alarm Management (B0700AT) for more information.

AIM*Historian AIM*Historian collects, processes, and stores control data for trends, logs, reports, spreadsheets, and application programs. A typical Historian database can contain a combination of process analog or digital variables (points), application-generated messages, and system and process alarms. You can configure the following types of data collection:  Point sample collection  Message groups (predefined groups only)  Archive groups  Manual Data Entry groups For these data collections, you can configure and edit point members, groups, group members, and Manual Data Entry variables. For more information, refer to AIM*Historian User’s Guide (B0193YL).

Integrated Control Configurator Use the Integrated Control Configurator to define blocks and logical groupings of blocks (called compounds) to perform specific control tasks, and to install them into a control station. The configurator also lets you configure Equipment Control Blocks (ECBs), which provide the software communication link between the control blocks and the hardware. For more information, refer to Integrated Control Configurator (B0193AV).

Top Priority Display The top priority display can be a Block Detail Display or a user-built display. It refers to the display associated with the highest priority alarm, according to the sort option configured for the Alarm Alert database. From an alarm display, you can access the top priority display by clicking the Top Priority button. Refer to the Alarm Manager On-Line Help or Workstation Alarm Management (B0700AT), for information about configuring the Alarm Alert database.

User-Built Displays User-built displays are displays created with FoxDraw or Display Builder (older systems). Refer to “Accessing a User-Built Display” on page 80.

Displays Created from FoxDraw FoxDraw built displays can take virtually any form and can provide access to control information for monitoring and manipulating your process. They can contain graphic objects that are updated dynamically from the process and objects that allow you to change process values. FoxDraw generated displays can include objects such as faceplates, trends, X/Y plots, and bitmaps.

Group Displays Group displays contain faceplates and trends grouped into unique layouts with connections to different blocks to meet changing operational needs. For example, a group display can include four faceplates over four trends, together with control buttons for acknowledging an alarm, toggling a Boolean value, toggling an Auto/Manual state, or calling up a Block Detail Display. A faceplate can show a block description, measurement, and outputs. Use a faceplate to manipulate the block state and provide direct access to Block Detail Displays.

Supervisor Setpoint Control (SSC) If your system is configured for Supervisory Setpoint Control (SSC), a supervisory application can control setpoints, ratios, or measurement values. All I/A Series Control Processors (CPs) and most Application Processors (APs), Workstation Processors (WPs) and Application Workstations (AWs) support SSC. The AP10 does not support SSC. The WP20 supports all features except the timer enable/disable actions and the supervisory control enable/disable actions at the group level. The system engineer assigns blocks to one of eight supervisory groups maintained in the Station block. From a Station Block Detail Display, you can enable/disable SSC for a group of blocks. Refer to Process Operations and Displays (B0700BN) for details.

How SSC Works In simplified terms, SSC works as follows:  The supervisory application receives a setpoint, ratio, or measurement from each block as a back-calculated value.  The supervisory application sends a separate supervisory setpoint, ratio, or measurement to the appropriate control block in a supervisory group.  Each time the supervisory setpoint, ratio, or measurement is sent, it resets a fallback timer associated with one of eight supervisory groups.  If the supervisory application fails to send the supervisory setpoint, ratio, or measurement within a specified time period, the group fallback timer expires and the blocks in the supervisory group fall back to the originally configured control mode.

While a Block is Under SSC While a block is under SSC, an operator:  Cannot set parameters (that is, Local/Remote (LR), Set Point (SPT), Remote Switch (REMSW), Local Switch (LOCSW)) associated with the setpoint.  Can lock out write access to setpoint parameters when SSC is enabled and can lock out other operators from write access to block parameters. You can request (initiate) fallback action for any group (if the group is configured for fallback), and enable/disable any group timer. The use of the timers is optional. If automatic fallback is not desired, the timers can remain disabled. Without automatic fallback, when you disable SSC in the supervisory group, control falls back to the configured mode. At the individual Station Block Detail Display, you can also enable/disable SSC for a block and request fallback on an individual block or group basis.

Group Device Assignments Overlay The Station Block Detail Display includes a Group Device Assignments overlay. This overlay shows the system output devices (for example, printers) assigned to alarm message groups via the Integrated Control Configurator. You specify the device names and a hexadecimal value that assigns the devices to the group by editing the Station block in the letterbug_STA compound via the Integrated Control Configurator. The overlay shows generic device names, DEV 1 to DEV 16 (LP001 is typical for a printer), and the group hexadecimal value. You can assign up to 16 devices to up to five groups (GR4 to GR8). Messages assigned to a specific group are sent to all the devices whose bit is set true (1) for that group.

Trends Overview of Trends A trend consists of:  A graph area  Numerical readout fields  Pause and scroll buttons. The trend’s graph area includes lines (pens), representing changing real-time data values or values from a historical database. Trends can be configured for auto-scaling, which adjusts the maximum and minimum scale values (Y-axis) according to the current data points being displayed. Figure 2-6 represents a typical trend.

Trend Data Trend data is plotted as a series of data points, each point representing the value of a variable at a given moment in time. These plotted points are connected by straight lines and are scaled according to the high limit and low limit configured for each trend line. Data scrolls to the left as new data is entered. The new data appears at the configured scan rate. Trending supports:  Up to four trend lines (pens) per graph representing real, integer, or packed Boolean data  Trend duration displayed in HH:MM:SS (hours, minutes, seconds)  Real-time data collection at a configured scan rate  A data parameter name (such as MEAS) and related numerical value (for example, 96.61)  Status conditions shown with different line styles. A BAD status is displayed as a dashed line, and the text field shows asterisks (*****)  Time stamp along X-axis on an even tick division. You can pause the trend to page forward and backward through historical data, and view a numerical readout for a requested time. FoxView display time is local time, adjusted for daylight or standard time. NOTE

For log scale data, values of 0.0 or less are displayed as 1.0, as the log (base 10) of these values is undefined. Refer to “Selecting a Time Period for Historical Data” on page 60.

Each trend is configured to be merged or banded. A merged trend can display up to four trend lines inside the same graph area. A banded trend displays each line inside an individual quarter-height area. Banded format is often used for auto-scale trends. Banded format can not be used for logarithmic trends.

Specifies A trend’s configuration can include the display of scale settings (labels) along the trend area’s Y-axis. Each trend pen (line) can be configured to include its own scales. Within FoxView, you can assign the pen for scale display. The scale color matches the color of the assigned pen. Each trend pen's data is plotted according to the pen's configured scale values, regardless of which pen's scale is currently visible on the Y-axis. If the Y-axis is visible, selecting within the Y-axis area displays the next trend pen's scales. Each scale is displayed in the color of the trend pen. Each trend can have a set of four static lines configured either through the Advanced Graph tab in the OnLine Trend Configurator or the Pens tab in FoxDraw. Each trend can be configured to display -1 to 4 decimal places in the OnLine Trend Configurator or the Timing tab in FoxDraw.

Real-Time Trends and Historical Trends A real-time trend displays continuously updating trend graphs. Only the most recent data appears on the graph. NOTE

You can also view historical data. A historical trend provides data from a database file. Trend data displays as a series of plotted points connected by straight lines. Data scaling on the vertical axis is according to high scale and low scale limits configured for each trend line, or according to auto-scaling provided by FoxView. The real-time trend data scrolls to the left as new trend data is added on the right. New data displays at the configured scan rate. However, if the configured scan rate is less than four seconds, new data is temporarily stored. (The display is not updated more often than every four seconds.) The grid is scrolled with the trend data. For trending historical data, scrolling buttons near the bottom of the trend allow you to scroll the trend to the left or right. The Pause and Update buttons provide a means of toggling between trends representing real-time and historical data.

Auto-Scaling and Guardband FoxView performs the auto-scaling two ways:  Enlarging the trend scales – As new data is displayed, FoxView determines whether the new data can fit within the trend graph. If the data does not fit, FoxDraw rescales (and redraws) the graph area. Rescaling occurs as trend peaks (highest recorded values) are added to the trend area.  Decreasing the trend area – In addition to scale validation during updates, FoxView also checks all currently displayed data at configured time intervals to determine whether the scales can be reduced to increase trend resolution. Rescaling is performed as trend data peaks are scrolled off the trend area. When rescaling trend lines, FoxView adds a pre-configured guardband above and below the newly calculated scales. This area provides a buffer area for displaying new data that falls outside of the new scales. Guardband is configured as a percentage of the recalculated scale, and has a default value of 10%. At this default setting, a trend line occupies 80% of the graph, with a 10% buffer both above and below the line data. In addition to a guardband, a minimum span is also configured. This prevents the absolute span from becoming too small, as may be the case when nearly straight lines are recorded. This minimum span is configured a percentage of the data point’s full scale, and defaults to 10% of scale. The following items are also noteworthy with regard to auto-scaling: 

Once a line has been set up for auto-scaling, the numerical updating value on the trend is surrounded by a rectangle in the pen’s color. This indicates that auto-scaling is currently in effect.  Before a trend is redrawn, all other trend lines are checked for the condition described under “Decreasing the trend area” (second bulleted item above). When the Auto-Scale function is in effect, FULL SCALE, ZOOM, and SHIFT are inactive (dark brown) on the Online Trend Configurator.

Online Trend Configuration FoxView includes an online trend configuration capability. To access this capability, your environment must have the necessary access levels (permission). Online trend configuration allows you to change the contents and general appearance of a time-based trend after it has been called into FoxView. The changes you make to a trend through this method are temporary; that is, these changes exist until the display is swapped out of FoxView. NOTE

If configured, the changes you make can be saved for future use. If you have the proper permission access levels, you can configure an online trend and view it immediately. In addition, if you have the proper permission, you can save the trend configuration, which overwrites the FoxDraw generated trend configuration for use with subsequent displays of the trend. NOTE

If a display contains more than one trend and you make changes to more than one trend, you must first save each changed trend before saving the entire display.

Major Steps of Configuring an Online Trend During an online configuration session, the FoxView display continues to update without interruption. All actions can still be taken from within FoxView. If the display being configured is closed, the Online Trend Configurator is also closed. Refer to “Online Trend Configuration” on page 121 for complete details. Refer to the Online Trend Configurator’s On-Line Help system for more information. An online trend configuration session includes these tasks:  Selecting a process variable (point) for trending.  Selecting a trend to which you assign the process variable. 

Assigning the process variable to a particular trend pen.  Configuring the pen’s scaling method (specifying minimum and maximum scale values).  Configuring the trend duration and trend presentation. These criteria affect all the trend’s pens.  Viewing the resulting trend. 

X/Y Plots FoxView supports X/Y plots (Figure 2-10) that allow you to plot two process variables against each other. You configure these plots through FoxDraw. An X/Y plot allows up to four relations to be plotted within a single plot area. FoxView supports a maximum of 16 plots per display. Plots consist of a trace line that shows all data points corresponding to the relation.

Figure 2-10. Example of a X/Y Plot

X/Y plots support both linear and logarithmic scales on both the X and Y axes. The color and visibility of grid lines are configured in FoxDraw. The relation data that is plotted can come from one of three sources:  Current real-time data  X/Y points from a read data file  Historical data. Use FoxDraw to configure FoxView to retrieve historical data, on a pen-by-pen basis, for X and Y data points individually and include this historical data in the X/Y Plot. FoxView supports the ability to retrieve X/Y plot data from an ASCII file, created with a text editor or a user’s application that contains data for a single relation. For the format of this data file, see FoxDraw Software (B0700BE).

B0700BD – Rev E

X/Y Plot Appearance The appearance of an X/Y plot is determined by:  The X/Y plot’s configuration (via FoxDraw), which defines items such as the number of points that can be displayed and the scan rate, the use of a time delay, whether markers are to be used, the X/Y plot’s background color, whether a grid is to appear, the appearance of X-axis and Y-axis scales, and plot relation labels. Additionally, the number of pens and their configured colors affect the X/Y plot’s appearance.  The X/Y plot’s object data file. This creates background objects and affects the color of points that lie in various portions of the X/Y plot area.  A pen’s X/Y plot data file. When an X/Y plot is invoked, data specified in an X/Y plot data file loads into the pen’s data buffer and is displayed on the X/Y plot.  Real-time and historical data values (compound:block.parameters values, shared variable values, or both).  Up to 50 static text fields within the graph area. You can specify the location, color, font, font style, and font size for each static text field.  Up to 50 polygon/polyline objects.

Markers An X/Y plot can display up to four series of plotted points (also called lines or pens). Each pen’s appearance can display:  A leading marker with the previously plotted points indicated by the vertices of a polyline (for example, -------o, or ------+).  A marker at each point (for example, ooooo or ++++++). The markers can be connected with polylines (for example, o---o---o---o). In the X/Y plot, the marker configured for the plotted pair appears in the area next to the names of the X and Y pairs. The example indicator in Figure 2-11 distinguishes plotted data on plots containing more than one plotted pair.

Figure 2-11. Plotted Data on Plots

B0700BD – Rev E

2. Process Displays

Color In addition to the marker (quantity and style) configuration, specifications made in FoxDraw for the X/Y plot’s background color and pen color (point color) affect the X/Y plot’s appearance. The newest X/Y pair can be drawn in one color, and previously plotted points may be drawn in a different color. Additionally, the color of the most recent point can be based on another variable. If one of the data values in a plotted pair is unavailable, out-of-service, bad, or in error, then no data is plotted for the pair. A data field indicates the data quality of the current values for each pair.

Plot Area Background The X/Y plot area is user-defined in FoxDraw. The plot area can include background display objects (by the inclusion of a data object file).

X-Axis and Y-Axis Scales Scales are displayed if all pens within the plot are plotted with the same scales. If this is not the case, FoxDraw allows you to select the relation's scale to be displayed by FoxView on the X-axis and Y-axis of the plot. You can also specify that no scales be displayed. In FoxView, the color of the X-axis and Y-axis scales indicate the relation whose scales are currently shown.

Real-Time Data Values Real-time values for the X/Y points are derived from Object Manager-connectable variables (process or shared) within the system. These values appear on the X/Y plot area at the configured scan rate, once per scan period. The number of values displayed and retained in memory (data buffer) is also configured in FoxDraw (up to 600 X/Y points). Once this buffer is filled, the oldest points are removed from the plot. The X/Y plot displays up to the configured limit within the plot. For example, if the plot is configured to display 300 points, and 400 points are read in from a data file, only the last 300 points are displayed within the X/Y plot. If the plot is configured for 300 points, after 300 real-time points are collected and displayed, the oldest point (301st point) is erased. If one of the data values in a plotted pair is unavailable, out-of-service, bad, or in error, no data is plotted for the pair. This data field (indicating the current values for each pair displayed) includes an indicator of the data quality.

Historical Data Values FoxView plots real-time plot values before retrieving historical data to ensure that delays in locating historians do not delay the display of real-time data. FoxView adds real-time data to the plot at the configured scan rate. FoxView places historical data received from the historian in a FIFO data buffer in front of the real-time data. When the plot reaches the configured limit, FoxView removes historical data points from the FIFO buffer as new data points are added to the plot. The color and marker style for plotted historical data are the same as that of real-time updates. If historical data cannot be retrieved for both parameters of a relation, FoxView plots no historical data. If a relation is configured for both historical data and read file data, FoxView only displays the historical data. 36

B0700BD – Rev E

Out-of-Normal Polygons FoxView displays out-of-normal polygons (polygons that represent out-of-normal processing values) on X/Y plots. Out-of-normal polygons can be closed objects or open objects. FoxView reads the data for the out-of-normal polygons from the object description file as described in FoxDraw (B0700BE). You can configure two behaviors with out-of-normal polygons:  As the most recent point of a plotted relation enters a closed polygon, the color of the point changes (plotted markers and connecting line segments) to the color configured in the polygon for the most recent point. If any relation is within the area defined by the closed polygon, the line color of the out-of-normal polygon changes to the configured color. If there are no longer any most recent points within the polygon, the line color of the out-of-normal polygon reverts to the original configured color.  As the most recent point of a plotted relation enters a closed polygon, the edge color of the polygon can be configured to change. As long as the most recent point of any relation is within the polygon, the edge color remains at the configured color. If a most recent point is within two polygons, only the edge color of the topmost polygon changes.

Optional Buttons on an X/Y Plot If configured, an X/Y plot can have buttons that permit you to:  Save (write) X/Y plot points to a file  Run an application program to perform a linear regression analysis on the X/Y plot points that have been saved as a file  Clear the plot area  Read a file containing X/Y plot data, displayed as points on the X/Y plot  Pause the plotting of points on the X/Y plot  Update the X/Y plot; resumes the plotting of points after a pause  Stop collecting data points  Start collecting and plotting data points  Flush the plot data buffers  Redraw the data that is stored in the data buffers.

X/Y Plot Functions Depending on the X/Y plot’s configuration, the display may include buttons allowing you to:  Write the X/Y pairs to a file (called an X/Y plot data file).  Perform a linear regression analysis on the points. An application program would use the X/Y plot data file as input. 

Plot data points from an X/Y plot data file. NOTE

The points plotted from the X/Y plot data file can be configured to be drawn on the X/Y plot in a different color to distinguish the points. 

Alarms Alarms and status messages are generated by alarm blocks and alarm options in certain blocks. These alarms have priorities from 1 to 5 (1 is the highest priority), allowing you to quickly focus on the most important plant alarm conditions. Each compound has an alarm summary parameter (ALMLEV) that contains the priority of the highest current alarm in that compound. To avoid nuisance alarms, you can inhibit low priority alarms at the compound level via the CINHIB parameter. Alarm messages from the blocks within the compound are sent to designated groups of workstations or applications (workstations, AIM*Historian instances, printers) according to the configured alarm groups.

ScratchPads FoxView installation includes a set of ScratchPad trends (named trend_list) and group displays (named group_list). Each of these ScratchPad applications allows you to set up a unique set of 20 trend overlays and 20 group displays for each FoxView environment. These overlays and displays are configured within FoxView, without using FoxDraw. Each of these ScratchPad sets has been implemented using existing FoxView commands and features. Both trend_list and group_list can be added to any FoxView environment. trend_list and group_list have been added to the Process_Eng environment. In addition, trend_list has been added to the Operator environment. In the directory /opt/fox/displib/ScratchPad/Common, refer to the files readme_trend.txt and readme_group.txt for installation and operational information regarding this feature. When added to an environment, a new menu entry appears in the menu bar titled ScratchPads, as shown in Figure 2-13.

Shortcut Menus FoxView provides context-sensitive shortcut menus of display commands for use in the Block Detail displays and user-built displays. When you click the right-click mouse button on an updating field, overlay, or base display, the assigned shortcut menu opens. If you right-click over an updating field, and the display also has menu commands associated with the display, the menu commands for the updating object appear first, and then the menu commands for the display appear. There are specific shortcut menus for use with specific operating environments such as the Operator or Process Engineer environment. In Block Detail displays, FoxView invokes the assigned shortcut menu when you right-click on an updating field, indicator bar, limit indicator, or other areas on the base display. Figure 2-14 shows an example of the default shortcut menu invoked when the process engineer right-clicks on the measurement indicator bar in the control with bias overlay of a PID block detail display.

Moveable Overlays FoxView supports moveable overlays (see overlay PIDC_11 in Figure 2-17). When first invoked, moveable overlays are located on the FoxView window in the same position as stationary overlays. However, you can move the overlays around or off the FoxView window. You can move these overlays anywhere on the desktop. On Windows multi-head stations, you can move overlays to any of the heads on the desktop. On Solaris multi-head stations, overlays are restricted to the head on which they were first invoked. Moveable overlays can be hidden behind the FoxView window, but the number of moveable overlays currently opened for each FoxView is displayed on the right of the FoxView status bar. You can either see the open overlays, or determine if some are hidden behind the FoxView window. On Solaris workstations, if any overlays are hidden behind the main window, you can use a View menu command to move all the overlays on top of the FoxView window. Moveable overlays have a standard window frame and title bar. You use the title bar and frame for selecting the window for repositioning and resizing. The window control menu is also available, allowing windows to be closed and iconized. The title bar contains the name of the overlay. A moveable overlay is initially displayed in a size relative to its FoxView window. In other words, a 1/4 screen overlay will occupy one quarter of the FoxView window, regardless of the actual size of the window. Moveable overlays are resizable. When resized, they retain their original aspect ratio. You cannot resize an overlay to smaller than it would appear if it were inside the minimized FoxView window. The minimum size for a FoxView window is generally specified as 1/4 the screen. When FoxView is iconized, all overlays are also iconized. When the FoxView window is closed, all the overlays close. FoxView supports a maximum of 16 stationary and moveable overlays. You can build moveable overlays via FoxDraw or include an argument specifying that the overlay to be invoked be moveable using either the ov and ov_conn commands. FoxView supports an embedded display script that is run when the overlay is closed. This feature configures overlays that have no Close button to be moveable and allows them to be closed from the window control menu. FoxView provides a way for overlays that were built with previous versions of FoxView to be made moveable. By default, however, FoxView opens all overlays in the manner in which they were built. Thus, FoxView opens all previously built overlays as stationary and all newly built overlays according to the way they were built in FoxDraw. Using the View menu commands, you can open stationary overlays and make them moveable, or you can open the overlays as built in FoxDraw. Clicking Moveable Overlays in the View menu forces all overlays built prior to FoxDraw release 9.0 to open as moveable. It also forces all overlays configured as “FoxView mode” in FoxDraw 9.0 or later to open as moveable. However, overlays built as stationary with FoxDraw 9.0 or later do not open as moveable. FoxView provides shortcut menu commands to switch stationary overlays to moveable and moveable overlays to stationary. Right-clicking a stationary overlay opens a shortcut menu from which you can click Moveable to change the overlay to a window that you can move by clicking and dragging the title. Right-clicking a moveable overlay opens a shortcut menu from which you can click Stationary to change the overlay to a stationary one.

5. Overview of FoxSelect This chapter gives an overview of FoxSelect and describes the different views available in the FoxSelect window.

Overview FoxSelect (the Compound and Block Overview Display) provides a representation of control databases. FoxSelect replaces the Select Screen in Display Manager. Use FoxSelect to:  Bring detail displays (Block Detail Displays, Compound Detail Displays, or Station Block Detail Displays) into FoxView.  Turn ON and OFF compounds and their associated blocks.  Expand a list of the network’s stations and compounds, revealing the hierarchical structure of the control database.  View a list of blocks within all connected stations, and sort the list by different criteria. The FoxSelect window provides two views, as shown in Figure 5-1.

Figure 5-1. FoxSelect Views 

Station View: A scrollable hierarchical view of stations and compounds on the left panel and a list of blocks for the selected compound on the right panel. For more information, refer to “Viewing the Control Database” on page 115.  Block View: A scrollable and sortable list of blocks within all connected stations. For more information, refer to “Viewing the Block List” on page 115. NOTE

The data in Station View and Block View are not updated until you perform a Refresh operation on the stations.

5. Overview of FoxSelect

Station View The I/A Series database is organized by stations, compounds, and blocks. The database can be viewed by placing FoxSelect in Station View. The stations and compounds appear on the left panel of the screen, while the blocks for the selected compound appear on the right panel.

Stations in the Database When you open the FoxSelect window for the first time after installation, only the stations appear. Each station, represented by a station icon, indicates its connection status, as listed in Table 5-1. Table 5-1. Station Status

Station Icon

Connection Status Unconnected

Indicates No attempt was made to connect the station, or the station has been marked to be excluded from Refresh All. An out-of-network station (a station that is not on /etc/wpcplns file), when unconnected, displays the same icon as that of the connected station, but deletes all compounds and blocks from the station view and block view. Note: A Refresh All does not change the connection status of unconnected stations. FoxSelect has successfully retrieved data for the station. Out-of-network stations are displayed with a green icon rather than blue. Attempts to connect the station have failed, rendering the data unavailable.

Report Views You can configure custom report views to display certain information on selected compounds or blocks in the connected stations that you select. Using search filters you can also limit the report to compounds or blocks containing specific characters. Predefined templates are available to provide information for the following conditions:  Compounds off-scan 

Compounds in-alarm  Compounds with alarms inhibited  Blocks off-scan  Blocks in-alarm  Blocks with alarms inhibited  Blocks not in control  Blocks in manual  Blocks with bad I/O. Figure 5-4 shows a sample view of the blocks-in-alarm report for a selected station. This report lists all the blocks in alarm along with the associated compound, description, and alarm priority.

Figure 5-5. Sample of a Blocks-in-Manual Report

Interfacing with FoxView Access for turning compounds ON or OFF is based on the current state of FoxView. If turning compounds ON and OFF is protected in FoxView, this capability is protected in FoxSelect. NOTE

If you enable access in FoxView, you must restart FoxSelect to read the new access information. Turning compounds ON and OFF is performed by the associated FoxView. FoxSelect sends a message to the associated FoxView. The FoxSelect window is not updated with new ON/OFF status information until all the compounds have been processed by FoxView. Since turning compounds ON and OFF is through FoxView, these actions are logged to the Operator Action Journal if this feature is enabled in FoxView. When running multiple FoxView sessions, be aware that FoxSelect communicates with the FoxView from which it was invoked. Refer to Display Engineering for Display Manager Software and FoxView Software (B0193MQ) for more information on setting up the ON/OFF access.

Show Detail Display

The action of this command depends on the type of block selected. For most block types, the behavior of this command is similar to the Show Parameter Detail Display command. The two block exceptions are:  PLB blocks  Sequence blocks with SFC configuration. Displays a block, compound or station detail display in FoxView. Note: This option always shows the Block Detail display for PLB and sequence blocks, in FoxView. When the option is checked, FoxSelect saves all the data about Compounds and Blocks into a dat file. When the application is restarted, it fetches all the Compound, Block information and populates the tree control of the station view and the list control of the Block View. The created dat file will be saved in \opt\fox\wp\FoxSelect for Windows and /opt/fox/wp/FoxSelect for Solaris named as FS. By default FoxSelect opens with Save and Refresh from file unchecked. Command Line Command:

8. Online Trend Configuration This chapter describes online trend configuration.

Overview of Trends A trend is a pre-built display object, configured in FoxDraw, which shows continuously changing data within a graph area. The data, which appears as a polyline within the graph, moves across the display from the right side to the left side. A trend can:  Display up to four independent process variables (points in the control system)  Display a label/description next to the trend line 

Show a variable amount of data, based on the trend’s duration and scan rate  Take one of two presentation formats (merged or banded)  Be configured to display different scales (min/max, max/decades, Boolean labels)  Be temporarily or permanently modified.

Online Trend Configuration Online trend configuration allows you to change the contents and general appearance of a time-based trend after it has been called into FoxView.

Real-Time and Historical Trends Trend areas display data (trends) representing changing data values from the real-time and historical databases. Real-time trend areas are continuously updating trend graphs, displaying the most recent trend variable data. Optionally, historical data from the AIM*Historian can also be displayed within the trend. Trend data displays as a series of plotted points connected by straight lines. Scaling of the data on the vertical axis is according to:  High-scale and low-scale limits configured for each trend line  Auto-scaling  Stored control processor (CP) values  Current limits. Real-time trend data scrolls to the left as new trend data displays on the right. New data displays at the configured scan rate.

121

B0700BD – Rev E

8. Online Trend Configuration

Trend Duration and Scan Rate You can configure the graph area attributes that control the trend duration and scan rate. Duration Scan Rate

The length of the period that is displayed on the trend. The time between plotted points.

Values for duration and scan rate are entered via the Data Rate Selection dialog box. If the duration and scan rate values conflict, the Valid Scan Rates dialog box presents one or more valid scan rates from which to select. To improve the speed with which changes in the field are reflected in the Trend, use the Fast Scan option in FoxDraw. Select Display Properties from the FoxDraw File menu and click the OM_Data tab in the Display Properties dialog box. The dialog box also allows you to set a Scan Rate and Scan Delay.

Duration and Scan Rate Rules The values for duration and scan rate rely on each other. If the scan rate changes, a new duration is computed. Conversely, if the duration changes, a new scan rate is computed. The values for duration and scan rate follow these rules:  The default value for duration is 15 minutes.  The default value for scan rate is 3 seconds.  The scan rate value has a minimum of one second (corresponding to a minimum duration of 60 seconds) and may change in minimum increments of whole seconds.  The ratio of duration to scan rate must be less than or equal to 600:1.

Trend Line Auto-Scaling FoxView can automatically scale a trend. The use of this scaling method continually resets a pen’s minimum and maximum scale values, based on the current data points being displayed. The resulting trend provides maximum resolution.

How FoxView Auto-Scales a Trend FoxView performs auto-scaling in two ways: by enlarging the scales and by shrinking the scales. As points are plotted, minimum and maximum scales are checked to determine whether new points fall outside of the current minimum and maximum. If points fall outside these limits, FoxView enlarges the scale to accommodate the points and redraws the trend. If all the points lie inside the scales (such that the scale minimum value would increase or the scale maximum value would decrease), FoxView shrinks the scale and redraws the trend. Scales are rounded up to the next whole number for maximum scale and rounded down to the next whole number for minimum scale. When rescaling of trend lines occurs, a minimum span value is configured as a percentage of the full scale to prevent the range from becoming too small. This value defaults to 10% of the scale and can only be modified within FoxDraw. All rescaling occurs when the new points are plotted. You can auto-scale trend lines on a line-by-line basis. Auto-scaling of a line is indicated in the trend area with data values surrounded by a rectangle, which is the same color as the pen. 122

Online Trend Configuration Online trend configuration allows you to change the contents and general appearance of a timebased trend after it has been called into FoxView.

Capabilities Online trend configuration capabilities allow you to:        

Assign a process variable to a trend pen Delete a pen from a trend Change a trend’s duration and scan rate Configure trend presentation (merged/banded, off-normal regions, grids, markers, colors, time stamp format, and pen data type) Select how a pen’s scale values are to be configured Add static lines at user-defined values Specify the number of decimal places a trend displays. Save configuration changes.

Boolean Pens Pens configured in FoxDraw to be Boolean, and which are not modified within the Online Trend Configurator, display as Boolean pens within FoxView. NOTE

Logarithmic trends do not support the Boolean pen type.

Permission to Configure an Online Trend Various features of the Online Trend Configurator may be protected from unauthorized use. Specific protection prevents unauthorized persons access from:  Accessing the Online Trend Configurator (TND_PROT).  Using the keyboard to specify the process variable or description for a trend pen (TLC_PROT, TLD_PROT).  Permanently saving online trend configuration changes (PSV_PROT). Refer to Display Manager Commands (B0193DF) for details.

8. Online Trend Configuration

Saving an Online Trend Configuration If you have access to the Online Trend Configuration dialog box’s Permanent button, after modifying a trend configuration, clicking this button saves the original trend display file. Access to the Permanent button may be denied based on the type of display that contains the trend being configured or based on the security settings of the current environment. The Permanent button is disabled when:  The current user does not have permission to make permanent changes  The trend is in a Detail Display  The trend is in a display that had been converted on invocation from a Display Manager packed display file (.pdf ) to FoxView display file (.fdf )  The trend is in a display that cannot be optimized.

Trend Presentation A trend can be configured to: 

Be merged or banded  Trend pen lines and markers  Include off-normal areas  Display grid lines  Display static lines  Use a local or regional time stamp. In addition, you can configure a trend’s data rate and scales.

Select and Assign Capability Use FoxView’s select point mode to select a process variable by picking an updating numeric graphic object (such as a tank level or moving marker) on a display. This capability allows you to assign an object’s connection variable to a trend line without using a keyboard. For example, when you are in select point mode and you pick an updating tank, the tank level connection is selected and the connection variable is available for assignment to a trend line. When selecting an updating graphic object with the right mouse button to copy the connected variable to the clipboard, all process variables that are connected to the object get displayed in the selection menu. For example, the process variables for both the Fill level and Fill color connections are displayed in the pop-up menu. Either menu item may be selected. Connected variables are often copied to the clipboard so they can be assigned to a trend pen. NOTE

Some process variables are not appropriate for trending. For example, although .BLKSTA and .ALMSTA are parameters that are often used in process graphics, these parameters are bit strings and cannot be trended without specifying the bits to be trended.

Keyboardless Assignment of a Selected Object to a Trend Line Keyboardless (mouse-based or pointer-based) assignment of a selected object connection variable to a trend line is performed using a ScratchPad or non-ScratchPad display, in conjunction with FoxView’s Select and Assign capability. Before assigning the selected object connection variable to a trend line, note that:  The assignment of Boolean data (packed Boolean or packed long parameters) is supported only in part by the Select and Assign function. If a Boolean data type is assigned, the trend line displays the data (0 or 1) as a numeric trend line, with a range of 0 to 100. The data type can be changed only within FoxDraw, not within the Online Trend Configurator. 

The FoxView with the source connection need not be the same as the FoxView with the destination trend area; however, the two FoxView applications must display on the same screen of a single-head configuration, or on either head of a multi-head configuration. The Select and Assign capability does not work across multiple desktops. Both FoxView and Display Manager can be used interchangeably as the source or the destination.  Once a selected point is assigned (retrieved), the selection is cleared and the selection process must be repeated if the point is to be assigned to another trend line.  The newly trended point acquires default parameters (such as ranges and engineering units) from the Control Processor’s database. You must access the Online Trend Configurator to modify these default values.  The AIM*Historian instance for the selected point is automatically found.

Trend Scales Configuration The scales you configure for the trend depend on whether the trend is linear or logarithmic.

Linear Trends A linear trend allows you four ways to configure the maximum and minimum values. Auto-scale CP Values User Entered

Use Current Limits

FoxView uses auto-scaling for the pen. FoxView uses the values stored with the Control Processor (CP). Allows you to enter the minimum and maximum values for the scale. You can type in the Max and Min fields, or use the zooming buttons and arrow buttons to adjust the range. Sets the scales based on the trend data currently displaying in the online trend. This button provides a one shot capture capability that reads the current maximum and minimum values of the data points in the display and sets the scale range based only on their data values.

125

B0700BD – Rev E

8. Online Trend Configuration

Logarithmic Trends A logarithmic trend that uses Boolean data allows you to configure a state 0 name and a state 1 name. A logarithmic trend that uses numeric data allows you to configure these items: Max Low Decade

The maximum scale value. The number of the low decade, which is equal to the exponent.

Numeric Data Whether the trend is linear or logarithmic, for numeric data, you can specify: Delta Engineering Units Guard Band Minimum Span

The deadband. The engineering units. The additional range or buffer added to the calculated range when FoxView determines the range for an auto-scaled pen. The absolute range between the minimum and maximum values set by auto-scale. For example, if Minimum Span is set to 5.0, this is the minimum range for the pen.

Online Trend Configuration Session If you have the proper permission (access levels), you can configure a trend and view it immediately. If you have the proper permission, you can also create and save a new trend configuration, which overwrites the current configuration and is automatically launched in subsequent applications of the trend. NOTE

If a display contains more than one trend, each trend is permanently saved independently. Saving one trend does not affect the configuration of other trends. During an online configuration session, FoxView continues to update without interruption. All actions can still be taken from within FoxView. If the display being configured is dismissed, the Online Trend Configurator is also dismissed. Only one Online Trend Configurator session is allowed at a time for each FoxView.

Configuration Session Tasks An online trend configuration session includes these tasks:  Selection of a process variable (point) for trending.  Selection of a trend to which to assign the process variable.  Assignment of the process variable to a particular trend pen.  Configuration of the trend, including:  Selection of graph attributes (data rate, presentation)  Selection of pen attributes (data type, scaling, color, label, markers).  Review of the resulting trend. 

9. FoxView Utilities This chapter provides a description of the pos_win utility with examples.

pos_win Utility Use the pos_win utility to size and position windows on a workstation. Description

The pos_win utility moves a window to a specified location, changes a window size to a specified size, or both. If the window is iconified, the window opens as specified in the command. A window is identified by the text in its title bar. If the text matches any part of the title bar text in a particular window, that window is considered a match. If more than one window on the workstation contains matching title bar text, only the first matching window is used. Instead of making multiple calls to the pos_win utility to position multiple windows, you can provide a file containing multiple window titles to the utility. On Solaris workstations, hostname may be specified, allowing the pos_win utility to affect windows on a remote station. Utility Location

Description Prints a list of all the window titles on the workstation. Displays a list of arguments. Specifies the name of the input file that contains title-match-text information. Identifies the window to be sized and positioned. The text may be any part of the window title string, not necessarily the complete title. If the text contains multiple words, surround them with quote characters (for example, “FoxView AW0001:AW0001”). (Solaris only) Specifies the name of the X Server. Specifies the width and height of the window in pixels. Specifies the position of the upper-left corner of the window in pixels. Specifies the status of the window i.e. show, restore, minimize or maximize. Note: This -status option is presently supported only for windows platform.

pos_win Utility Examples These examples demonstrate the use of the pos_win utility.

Example #1 The following command moves the FoxView window to the upper-left corner on a workstation named AW0001: pos_win “FoxView AW0001:AW0001” -size 500x500 -position 0x0 NOTE The title-match-text is surrounded by quotes, since this is a multi-word title

string.

NOTE The title-match-text AW0001 would also match this window title, but this work-

station may include many windows with this string in the title. Locating the specific FoxView window requires that the title-match-text contain the text “FoxView”.

Example #2 You can specify multiple windows in a single command by creating a text file, containing the following lines: “FoxView AW0001:AW0001” -size 500x500 -position 0x0 “FoxView AW0001:AW0002” -size 500x500 -position 500x250

Then, issue the following command, in which filename is the name of the file containing the window specifications. 144

10. Profile Plots This chapter describes the line and bar profile plots that comprise a series of data values plotted against a specific X-axis engineering unit. The profile plot area displays a series of data points along its X-axis. The X-axis may represent, for example, length, distance, or frequency. The Y-axis represents the value of each data point. Up to four color-coded sets of data points may be displayed in the plot area in either a line style or a bar style. Only linear scaling is supported on the X and Y axes. Figure 10-1 shows an example of a multi-line profile plot for a paper-manufacturing machine.

Figure 10-1. Multi-line Profile Plot

Both the line and bar style profile plot use color to indicate: 

Each line or bar line (1 to 4) with data values within normal limits  Each line or bar line of data values exceeding alarm limits  Each reference line (1 to 4)  The fill colors for bars, if filled bars are configured. The profile plot supports NAN (Not-A-Number) values. Because NAN values are not displayed, line gaps in the profile plot indicate the NAN values. The profile plot area is user-defined. Within FoxDraw, you can access different-sized plots from the profile-templates directory (\opt\fox\displib\ProfilePlots).

B0700BD – Rev E

10. Profile Plots

The following profile plot attributes are configurable via FoxDraw: 

Number of pens and their colors



Number of points that can be displayed  Profile style (line or bar)  Reference line  Scan rate for the trigger  Appearance of markers  Profile plot background color  Appearance of a grid  Number of grid lines along the X-axis  Appearance of the Y-axis scales. Operator buttons, typically located at the bottom of a plot area, can be configured via FoxDraw to allow you to:   

148

Select the configured plot area to execute a display command such as accessing an overlay or displaying read-out values. Toggle between the pause mode and unpaused mode. When in the paused mode, the plot area is not updated. Read out a data point by selecting the point along the X-axis. A vertical hairline appears at the selected X-coordinate, and the point number and value on each line are recorded in FoxView memory and optionally displayed in the read-out fields in the profile area. After performing a read-out, select a button to send the point number and value for each line to the configured compound:block.parameter or shared variable. Select an object configured with both read-out and send, in order to read and send point numbers and values with one selection. Request FoxView/DM to redraw the profile plot.

10. Profile Plots

B0700BD – Rev E

Profile Plot Appearance Each of the plot lines (line or bar) has its own: 

High and low scale values  High and low alarm limits, and  Reference line value. This information is available from the profile-line-options configuration information or if not configured, from the Data Header record in the Data Array. When the high and low alarm limit values are exceeded, a line or bar is drawn in the specified alarm color (see Figure 10-2). The fill color of a bar that has exceeded the alarm limits changes to the alarm color (see Figure 10-3).

B0700BD – Rev E

10. Profile Plots

Figure 10-3. Bar Profile Plots with Alarm Limits and Reference Lines

Lines or bar lines can be drawn: 

On the X-axis from left to right (see Figure 10-1) or mirrored along the Y-axis (called “reverse X-axis”).  With a reference line indicating either the median value of the data (Figure 10-3) or located on the X-axis representing the low scale value. When “reverse X-axis” is configured, the profile line is mirrored through the Y-axis. The line that is normally drawn from left to right is drawn from right to left creating a mirror image. Depending on the profile style selected, the reference line (optional) is drawn under or on top of the line. When “line” is configured, the reference line appears under the plot line; when “bar” is configured, the reference line appears on top of the bar line. The color and value of the reference line are configurable via FoxDraw. The reference line value is defined either by the display file, a process control variable, or the data-array header. It may be the median value or the low scale value represented by the X-axis. For example, the bar graph in Figure 10-3 has a different appearance depending on whether the reference line is the median value or the low scale value represented by the X-axis. If any of the data values in a plotted profile is unavailable, out-of-service, bad, or in error, then no data is plotted for that point. A blank appears at that data point. In line plots, a break appears in the line. In bar plots, the bar is not plotted for that point number. On the read-out value field, ***** appears.

Operator Buttons and Data Fields Profile plot displays typically include operator buttons at the bottom and data fields at the top of each plot area. For the bar and line profile plots of Figure 10-2, the Point, Value and Time fields provide the point number and current value and time for the bar and line profile plots. The Prev Display button opens the previously displayed profile plot. The buttons in the line profile plot of Figure 10-4, allow you to pause or redraw the profile plot.

Figure 10-4. Line Profile Plot with Operator Buttons

Data Updates All data points on a profile plot are updated simultaneously and the previous values are discarded. A profile plot (line or bar) with multiple configured lines has the following line priority scheme: Line 1 has the highest priority, Line 2 has the next highest priority, and so forth. The lines are drawn on the screen in the following order: from Line 4 (lowest priority) to Line 1 (highest priority). When one line is redrawn, all the other lines are also redrawn. In bar profiles, when a single point changes every bar is redrawn.

B0700BD – Rev E

10. Profile Plots

Profile Plot Data The data to be plotted is a set of string variables, which consists of Object Manager shared variables. The data source for the set of string variables is an application program. The data source maintains an Object Manager list variable (the trigger connection), which is altered each time a change is made to the data stored in the string variables. The connection trigger name for each plot line is configured in FoxDraw. Each profile line is connected to a trigger path variable via a change-driven connection. When a new value appears in the trigger variable, FoxView reads (via the Data Array path name) all the values from the set of string variables to be displayed. When the trigger connection and the data array connection names indicate that both variables are in the same station, the FoxView/DM will use the OM list references to retrieve the PSAP address through a getval_list() OM call. To be valid for such a call, the Trigger name and Data Array name should be: Data_Array_Name=trigger_name01

For example:

Trigger Connection Name: Data Array Name:

PAPER PAPER01

In case the names do not match the syntax described above, a single global_find() call is issued per trend line, which causes an IPC broadcast message. All the data arrays for the same profile line must be located on the same station; thus they must have the same PSAP address. For optional connections, all the optional OM data variables must reside in the same station. The PSAP address is retrieved through a global_find() OM call once. If the global_find() call fails, no more attempts are made to retrieve the PSAP address or any of the optional connection data. It is recommended that:  

Per profile area, the trigger connection and the data connection variables reside in one station Per profile plot line, the optional input connections all reside in the same station. NOTE

1. Profile plots do not support connections to individual data points or individual bars. 2. The number of data points is not necessarily the width of the graph area in pixels. FoxView/DM expands the space occupied by each point to fill the width of the graph area. 3. When a plot line has more points than pixels, the points may overlap when the plot line is drawn. String variables are capable of holding multiple values to be plotted. The maximum length of string variables is 255 bytes. Therefore a string variable can hold a maximum of one of the following:   

152

63 float or long values 127 integer values 255 byte values.

The first Data Array contains the Data Header information as well as a set of data values. The Data Header includes the following information, which is only used if not defined in the profile plot configuration: 

The data type being used (always used)  The number of points  High and low scale limits  High and low alarm limits  The reference value. Therefore, the first Data Array cannot hold as many data points as subsequent data arrays. If the number of points in a profile plot exceeds the number of data values available in the first Data Array, additional string variables are used. (Table 10-1). When multiple strings are required, the subsequent Data Arrays contain the same path name as the first Data Array with the exception of the last two characters. These characters are automatically substituted with a number depending on the array, for example, 02 for the second array, 03 for third array ... 59 for last array. Table 10-1. Contents of Data Arrays

Type FLOAT LONG INTEGER BYTE

Type Length

Number Of Values In First Data Array

Number Of Values In Subsequent Arrays

4 4 2 1

55 55 114 234

63 63 127 255

If you need to display 480 data points that are stored in the data array type “float”, the number of string arrays needed is:

1 + (480-55)/63 = 8 data arrays These 8 string arrays may be named, for example, FLOATARR01, FLOATARR02 ..... FLOATARR08. When the 480 values are packed into the data array type “integer”, the number of arrays needed is:

1 + (480-114)/127 = 4 data arrays Packing the same 480 values into a byte array would result in 2 arrays. A special tool (/opt/fox/bin/tools/omary50) is used to create, get, set, or delete the Object Manager string arrays. Refer to Object Manager Calls (B0193BC). To engineer data array access, refer to Display Engineering for FoxView Software and Display Manager Software (B0193MQ).

Appendix A. Frequently Asked Questions This appendix lists the answers to frequently asked questions (FAQs).

FoxView Why did dmsepass not change the environment password?

Probably the environment name argument was not entered correctly. The environment names are the names that appear in the Change Environment dialog box, not the name of the file. For example, the Process_Eng environment is made up of many files: Process_Eng.env, Process_Eng.mbr, Process_Eng.dbr. The correct way to change the password is with the command: dmsepass Process_Eng -p new_password

Can I increase the FoxView cursor size on Solaris to make touchscreen work easier?

Yes, the FoxView cursor can be changed to a large cursor. Change this line: /usr/fox/wp/data/init.user

to the following line: FXCURSOR=/opt/fox/wp/FoxView/cursor/crosshair_large

The cursor size does not change until the station is rebooted. What can I do to shorten display call-up time?

1. Obtain the fastest possible workstation and do not overload it.  The P79 and P80 are the fastest Solaris workstations.  The Windows XP based P92 is the fastest Windows workstation. If you are running on a slower box (such as 85 MHz or 110 MHz SPARC5s) with one FoxView/FoxDraw, install the 170 MHz CPU upgrade. Refer to P0971VJ. NOTE

This upgrade is for SPARC5s only. It does not work on a SPARC4® (Model 51B). SPARC4s run at 110 MHz.

2. Configure the displays in FoxDraw to use the Fast Scan option, as described in FoxDraw Software (B0700BE). 3. Call-up is generally faster on WPs than on AWs because WPs compete less for system resources. Do not use four FoxViews if you only require two FoxViews. Do not use two FoxViews if you only require one FoxView. WPs are intended to be operator workstations. AWs are intended to be engineering workstations. If call-up time and security are major concerns, do not try to save money by forcing AW functionality and overhead onto operator workstations. 4. Use one font only. As often as possible, keep font sizes the same. Do not use more than two font styles and three font sizes. Use the same font style and size for updating text. Human interface designers suggest using one font:  Helvetica on Solaris workstations  Arial on Windows based workstations. 5. Use the fewest number of display connections as possible. Call-up time is proportional to the number of connections. 175 points is considered a large display. The use of more than 175 points slows down display call-up time. 500-point displays can be created fairly easily, but require a call-up time of six to eight seconds (or more). 6. Be judicious with 3D objects. Use as few “fancy” objects as necessary to communicate the idea. ! CAUTION It is possible to create 100,000 polygons in a matter of seconds by copying and pasting fancy tanks, turbines, and other objects. Observe precautions. 7. If possible, use submodels for fancy graphics. If you have more than two of the same configured object, such as a valve with fill color connections, use custom faceplates. Custom faceplates are preconfigured graphical objects in which all connections are made to the same block. The compound:block association is made once and applied to each parameter configuration, as would be done in a conventional PID faceplate. 8. Always test call-up time as you are building displays. Do not spend weeks creating hundreds of complex displays only to learn that the displays take six seconds to call up when the process application requires a two-second call-up time!

9. If you plan to perform a remote draw from a Solaris FoxView to a PC X Server, use 32-bit X Server software. Ensure that the PC has at least 32 MB of RAM. NOTE

Windows 3.1 and 16-bit X Servers cannot do the job. If you are going to use an X Terminal, ensure that it has at least 32 MB of RAM. X Terminals, which have no virtual memory, are starved for memory. X Terminals are not cost effective WPs. Do not attempt to run configurators (such as ICC) on X Terminals. If the network connection breaks, or someone powers down the X Terminal, ICC is left running with no way to exit. This leads to the CP database being out of sync with the ICC work files, requiring a major clean up. Remember that X Terminals are not WPs. They are inexpensive because they have extremely limited capability. A remote FoxView uses the resources (memory and CPU) of the station that hosts it. 10. Keep the following in mind when configuring your system:  If you process many Display Manager (dmcmd) commands when opening overlays, the commands are processed serially.  If your display button is configured to run several commands and then open the overlay, there is a delay while the commands are being performed. 11. Use links to commonly used objects, rather than copies.

Appendix A. Frequently Asked Questions

How should I distribute display files to workstations?

The main issue is the possible corruption of display files. When you close a display, the display is saved to disk. Corruption can occur if the display is copied while it is being saved. To avoid corruption, ensure that the displays are not being changed on the workstation as the updated displays are being distributed. The safest way to distribute displays over these workstations is to call in a static display on the workstations and not allow the display to be changed until the distribution is completed. It is not necessary to optimize the displays before distribution.

FoxSelect The docking positions for toolbars cannot be changed when in touchscreen font state. What is the reason?

When in touchscreen font state, the toolbars are always docked at the top left corner of the application window and cannot be moved. This feature prevents the movement when the toolbar buttons are selected in the touchscreen font state.
