CHAPTER 1
Chapter 1 Overview Introduction The Human-Machine Interface (HMI) for SPEEDTRONIC turbine control is an operator interface for real-time control of power-plant processes and equipment. It ® runs on a computer-based workstation using a Microsoft Windows Operating System. The HMI provides operator display and control for the Mark* IV, Mark* V, Mark* V LM and Mark* VI turbine controllers. This document, Volume I, covers HMI operation. It is written as a guide to help the ® operator in using applicable HMI and supported CIMPLICITY HMI functions with the SPEEDTRONIC Mark IV, Mark V, Mark V LM and, Mark VI turbine controllers. Volume II covers HMI maintenance features.
HMI Overview The Human-Machine Interface (HMI) for SPEEDTRONIC turbine control is a operator interface for real-time control of power-plant processes and equipment. It runs on a pc-based workstation using client-server architecture. The HMI provides operator display and control for the Mark IV, Mark V, Mark V LM, and Mark VI turbine controllers. The HMI can be configured to operate with a variety of system devices, integrating plant operation at a single level. Plant operators and engineers can view and control plant equipment through a common interface. The HMI uses many different software packages to perform its functions. The primary package used for the operator interface is CIMPLICITY HMI. An operator can use the HMI for the following turbine control functions: •
Monitor one or more turbines through graphical displays (for example: alarms, wheelspace temperatures, and vibration levels).
•
Issue commands to the selected turbine or driven device (for example: Start, Stop, Cooldown On, Auto, and Raise/Lower Output). Note CIMPLICITY HMI is a product of GE Fanuc Automation.
Product Features The HMI contains a number of product features important for power plant control: •
Dynamic graphics
•
Alarm displays
•
Process variable trending
•
HMI access security
•
Maintenance functions such as logic forcing and user-defined point displays
GEH-6126C Vol I HMI Operators Guide
Chapter 1 Overview • 1-1
HMI Components The turbine control HMI consists of the following functional components (Refer to figure Data Flow between HMI Components): •
CIMPLICITY HMI is used primarily to display turbine status screens, which enable an operator to monitor the unit(s). Refresh rate is typically 1 second. CIMPLICITY is not used to configure the turbine control. –
An HMI Server connects to the controllers to retrieve and display realtime data. It optionally makes this information available on the Plant Data Highway. HMI Servers typically also provide the programming toolsets for turbine controllers.
–
An HMI Viewer contains the operator interface software, which allows the operator or maintenance personnel to view screen graphics, data values, alarms, and trends, as well as to issue commands, edit control coefficient values, and obtain system logs and reports. The HMI Viewer gets its real-time data over the Plant Data Highway from an HMI Server.
Note GFK-1180 provides a detailed description of the capabilities of the CIMPLICITY product. •
•
•
Turbine Control Interface (TCI) is a software package used to communicate with Mark IV and Mark V controllers to retrieve real-time information and alarms. It also provides the programming toolset for the Mark V controllers. Specialized displays are included for specialty functions such as logic forcing and displaying high-speed data. TCI performs the following functions for the turbine controllers: –
Mark IV: Provides real-time interface for data and alarms
–
Mark V: Provides real-time interface for data and alarms, specialized displays, and the programming toolset to configure a Mark V.
–
Mark VI: Provides real-time interface for alarms.
TCIMB (TCI/CIMPLICITY Bridge, previously called CIMB or CIMBridge) is an interface between the CIMPLICITY and TCI, as follows: –
Enables CIMPLICITY to collect data and alarms from controllers supported by TCI.
–
Forwards setpoint and alarm commands from CIMPLICITY to TCI for controllers supported by TCI.
System database (Mark VI only) establishes signal management and definition for the control system. It provides a single repository for system alarm messages and definitions, and defines mapping between controller software and physical I/O. Additionally, it defines Ethernet Global Data (EGD) exchanges, which provide the HMI with controller real-time data. Access to the database is required when configuring the system, but is not required while running.
Depending on the size of the system, these elements can be combined into a single computer, or distributed in multiple units. The modular nature of the HMI allows units to be expanded incrementally as system needs change.

Graphic Displays The HMI uses the graphics and alarm features of the CIMPLICITY software to provide an operator interface integrating many different types of controllers. The graphical displays offer representations of equipment in real-time. The HMI displays data and processes operator commands using screens that represent a variety of signals, their values, and units. Display items change color based on logic signals, while certain objects are dynamic and refresh with every data update, like bar graphs. Normal viewing allows the displayed data to be updated once per second, and special tools allow collection and storage of data at faster rates. HMI graphic displays include main unit, vibration, sensor readings, control setpoints, alarms, permissives, logic forcing, demand display, sequence editor, dynamic rung display, trip history display, trending, and many others depending on the application. An operator can view alarms from any HMI on the network as they occur. Note Screens are developed using preconfigured graphic building blocks that provide commonality to different plant applications that use the HMI.

Note Refer to GEH-6126 Vol. II and individual controller documents for more detail about the networks and protocol used for HMI communication. For Ethernet TCP/IP communication to third party equipment, such as a distributed control system (DCS) the HMI provides GE Industrial Systems standard messages ® (GSM) and Modbus protocol. GSM application layer protocols support four classes of application-level messages: administration, event-driven, periodic data, and common request messages. Alternatively, communication to remote DCS equipment is available through a Modbus interface, where the HMI acts as a slave to the DCS master. Such a system allows an operator at a remote location to initiate any operator command and to monitor turbine data.
Optional Features The HMI supports a Windows-based Historian computer, which collects and stores ® data from the control units for later analysis. OSI Software, Inc.’s PI-ProcessBook provides historical and real-time trending of all process data, and can run in the Historian and/or HMI Viewer. The HMI communicates with the Historian through the Ethernet-based Plant Data Highway (PDH) and through RS-232C lines. Note Document GEH-6422 provides information about the Historian.
GEH-6126C Vol I HMI Operators Guide
Chapter 1 Overview • 1-5
The HMI includes a time synchronization capability in both low- and highresolution forms. When redundant time masters are available, all turbine controllers and operator interface units on a system automatically select the same, highest quality time master. A Web Gateway allows operators to access HMI data from any computer on the network that includes the HMI. Third party interfaces allow the HMI to exchange data with the DCS, programmable logic controllers, I/O devices, and other computers.
Application-Specific Features When the HMI is paired with either the Mark V or the Mark VI turbine controllers, the turbine control software tools can be added to as an integral part of the HMI. The Mark VI features are based on the GE Control System Toolbox (toolbox). When the HMI is used in our Integrated Control Systems (ICS) product line or as a Balance-of-Plant (BOP) control interface, the ICS/BOP toolset becomes part of the HMI.
Technical Specifications Exact hardware and software specifications for the HMI are determined according to the needs of the customer and purchased options. The HMI workstation is typically sent to the customer with the HMI program already installed.

Optional HMI Displays Note The following HMI displays are not intended to be a guide to operating a turbine. The HMI displays are optional add-ons to CIMPLICITY. Only common optional displays are included.
Reactive Capability Display - Mark IV, Mark V, Mark V LM and Mark VI The Reactive Capability Display is a real-time graphic that displays the turbine generator's current MW and MVAR operating point (Refer to figure Example of Reactive Capability Display). The plot displays three lines of generator capability as a function of generator coolant temperature or hydrogen pressure. The operator can use this display to check how close the generator is operating to its thermal limits. To prevent the generator from overheating, the current operating point must be kept within the dynamic envelope displayed for the current conditions. Note The ratings curves are different for each application. They are displayed as an example only and should not be used unless they match the generator ratings. Displaying the wrong curves can cause operation outside the machine’s rated limits.
GEH-6126C Vol I HMI Operators Guide
Chapter 2 Quick-Start Procedures • 2-11
To get generator capability curves Click Gen Capability Three static curves represent the thermal limits of the generator at three discrete operating points. The curves are plotted at constant generator hydrogen pressure or constant ambient temperature, depending on the application.
Red dot represents the current generator operating point. It moves as the operating point changes.
Manual Synchronizing Display To bring a generator online with a power grid, the speed (frequency) and phase angle of the generator’s ac waveform must match that of the power grid. The preferred method is to use the turbine controller’s auto-synchronizing function.
Manual Synchronizing Display – Mark V and Mark V LM Mark V and Mark V LM – For Mark V and V LM, all data in the object is updated at 16 Hz. The Manual Synchronizing Display is run only from a HMI server. It must run on a server due to its fast update rate. If the Manual Synchronization option is enabled then both Automatic and Manual Synchronization share the same window for synchronization control. Mark IV – Refer to GEK-833810, Mark IV Speedtronic Gas Turbine Control System For Heavy Duty Gas Turbines, for more information. Mark V – Refer to GEH-6195, Mark V Turbine Control, for more information Mark V LM – Refer to GEH-6353, Mark V LM Speedtronic Turbine Control, for more information.

Triggered Plot Display Triggered Plot Display – Mark V and Mark V LM The Triggered Plot function provides a graph of high-speed turbine data. The graph can be triggered by the change in state of a logic signal in the unit. Turbine commands can be sent from this display, making it useful for initiating turbine tests (such as valve travel tests). Note The Triggered Plot function is run only from a HMI server. It is not run from a HMI viewer. It uses high-speed data (up to frame rate) that is only available from a HMI server. Only qualified personnel knowledgeable about turbine control and protection should create and execute commands. The commands can affect the control state and action of the unit control.

Viewing Trip Information - Mark V and Mark V LM Trip information is automatically gathered by the HMI from the controller. The last ten trips are stored on the HMI and can be viewed by using the Trip Log Viewer. The information about the last trip can be manually uploaded at any time, or the current accumulated data can be uploaded even without a trip. Mark V trip history information about the last trip is stored in the controller, and is lost if the controller is reset or rebooted. The HMI runs the automatic collection scan typically every five minutes, but the trip information can be uploaded manually before the controller is reset or rebooted. Mark V LM trip history information is stored in non-volatile memory and is not lost if the controller is reset or rebooted. Viewing Automatically Collected Trip Logs The Trip Log Viewer is used to view the trip log data. The user selects a valid unit and chooses a file from the list presented. The trips are identified by their date and time stamps. The latest trips are listed at the top of the list. After selecting the trip to be viewed, the results are displayed in a Notepad window.

CHAPTER 3
Chapter 3 Display and Control (Command) Programs Introduction The HMI provides an online database for collecting and storing data from multiple controllers. Refer to the controller documentation for description of the online database. The HMI’s display-only programs allow the user to view turbine control data as needed to monitor the system. User cannot, however, send control commands from these displays. The HMI’s control (command) programs allow the user to send commands to the turbine control.
Viewing Sequencing Information The program running in the controller that defines its control actions is called its sequencing. Sequencing typically consists of individual AND/OR logic operations (called relay-ladder logic rungs) and calls to library functions that do analog or complex operations (called primitive blocks or big blocks). Some controllers (such as the Mark V) use separate programs in the HMI to edit the sequencing and view the running sequencing. Other controllers (such as the Mark VI) use the same program for both, with a privilege level controlling whether changes to the sequencing are allowed. Both schemes allow the user to view the current running sequencing overlaid with the real-time data that is driving that sequencing. This is often useful for determining what conditions are driving a particular condition, such as what is preventing the unit from being ready to start, or what conditions are driving a particular alarm.
Viewing Sequencing Information - Mark IV The HMI has no knowledge of the sequencing running in the Mark IV controller, and as such has no sequencing display capability. Sequencing displays are available from the Mark IV controller's panel-mounted Operator Interface. The HMI does provide a Demand Display for Mark IV data, but it does not display the sequencing that creates the values. Note Refer to GEK-83865 and GEK-83866.
GEH-6126C Vol I HMI Operators Guide
Chapter 3 Display and Control (Command) Programs • 3-1
Viewing Sequencing Information - Mark V and Mark V LM The sequencing running in a Mark V controller is referred to as the Control Sequence Program (CSP). The HMI's Dynamic Rung display is used to view the CSP overlaid with the current values from the controller. The Dynamic Rung display program includes: •
Animation to display the current state of the control.
•
Relay Ladder Diagram (RLD) rungs.
•
Primitive and Big Block rungs. Some blocks include pictures of the sequencing inside the block.
•
Starting a Demand display with all of the signal names and values from the current rung.
•
A Find utility to display the locations and usage of all occurrences of a signal.
The following rules apply to the Dynamic Rung display: •
Can only display control segments from a single unit at any time.
•
Can display multiple control segments from the given unit.
•
Cannot be used to alter the unit’s CSP. The Dynamic Rung Display does not independently verify that the operator interface files match the unit control files. If these files do not match, the Dynamic Rung Display can display data that does not reflect the state of the unit control.
The Dynamic Rung display can save picture file displays in a text format for future reference. Any text editor can open these text files, but it should use the MSLineDraw font distributed with the TCI product.
Dynamic Rung Display Windows The Dynamic Rung display is a multiple document interface that allows the user to open windows with different segments or the same segment. The user can also have picture file windows and sub rung windows open.
Starting the Dynamic Rung Display To Start the Dynamic Rung Display From the Start menu, select Turbine Control Maintenance, Unit T#, then Dynamic Rung Display. Or From the Windows desktop, click the Dynamic Rung Display icon.

Viewing Sequencing Information - Mark VI The sequencing running in a Mark VI controller is viewed using the Control System Toolbox program. This is the same program used to create and edit the sequencing, but changes to the sequencing are only allowed if the user is running at a suitable privilege level. At the lowest privilege level the user can view the sequencing overlaid with the current values from the controller. Note Refer to Control System Toolbox for a Mark VI Turbine Controller for more information. When a controller is configured and downloaded, the live signal values can be viewed. This section defines how to go online to monitor these values and certain Summary Views when the controller is being monitored. These views are displayed when the Tracking button is on and an item is selected in the Outline View. Note Refer to Toolbox Documentation for more information. Typically toolbox opens the controller at a privilege level of 0, which permits Read Only functions. Operators typically run using this lowest privilege level to prevent inadvertent changes to the controller. To open the Toolbox window for the Mark VI 1

Viewing Trip Information Trips are defined as the unplanned (usually not requested) shutdown of the turbine while the unit is running. A normal shutdown is not considered a trip.
Viewing Trip Information - Mark IV An HMI has no Mark IV trip information display capability. A Trip Display is available from the panel-mounted Operator Interface. Note Refer to GEK-83865 and GEK-83866.
Viewing Trip Information – Mark V and Mark V LM Trip information is automatically gathered by the HMI from the controller. The last ten trips are stored on the HMI and can be viewed by using the Trip Log Viewer. The information about the last trip can be manually uploaded at any time, or the current accumulated data can be uploaded even without a trip. The information is viewed using Trip History. Mark V trip history information about the last trip is stored in the controller, and is lost if the controller is reset or rebooted. The HMI runs the automatic collection scan typically every five minutes, but the trip information can be uploaded manually before the controller is reset or rebooted. Mark V LM trip history information is stored in non-volatile memory and is not lost if the controller is reset or rebooted.

Viewing Trip Log - Mark V and Mark V LM A Mark V controller loses the trip history data stored in its memory if the unit control is reset or rebooted. A Mark V LM controller keeps the data for the last trip if a reset or reboot occurs. However, the Turbine Control Interface (TCI) includes a Trip Log Collection utility, TRPFIL that automatically collects and stores the data as a Trip Log file on the HMI. (Both the utility and HMI must be running during the trip.) The Trip Log file can be opened and viewed by the Trip Log Viewer function of the HMI. Refer to figure Mark V and Mark V LM Trip Log Viewer Dialog Box. Note Refer to GEH-6126 Volume II for information on the Trip Log Collection utility.
Opening a Trip Log File - Mark V and Mark V LM The Trip Log Viewer reads the previously saved trip text files stored on the HMI. It determines the trip times associated with each file from the name of the file, which is encoded with the trip date and time information. Viewer opens a viewer window and displays a list of the trips arranged in chronological order. Any Trip Log can be selected and displayed.

Saved Data is saved into the control memory when the user collects New Data. It remains in memory until it is overwritten by New Data or until the control is reset. New Data is saved to the control memory when the user collects New Data. The data reflects the most recent control data. The data remains in the control memory as Saved Data until it is overwritten or until the control is reset.
Note Collecting New Data overwrites the Saved History Data in the control. On Mark V units, New Data overwrites the Trip History Data in the control. Note Trip History data is lost in Mark V controllers if the unit control is reset before the HMI has saved the previous trip data. The trip history data is preserved in the controller memory over a unit control reset or reboot in Mark V LM units.

Viewing Trip Information - Mark VI The Mark VI controller uses the Data Historian, a toolbox program to collect and view trip history data. The Historian trip log is a combination of historical analog and discrete data. High-speed data is uploaded from the unit and merged with low speed data collected in the HMI for the 24 hours preceding the event. Note Refer to Data Historian document GEI-100278 and Trend Recorder document GEH-6408 for more information.
Trip Log File Data The Trip Log is a file which resides on an HMI and which can be viewed using the Trend Recorder function of the GE Control System Solutions Toolbox. The Trip Log contains data for a pre-defined group of control signal database points for a 24-hour period before the trip, and for a brief period (approximately 5 seconds) after the trip. The Trip Log also contains alarms, events and SOEs. The Trip Log file contains data at the various sample rates as displayed in Table, below. Trip Log Data Sample Rates
The last three rates are dependent on the Frame Period (scan rate) of the Mark VI and the number of pre- and post-trigger samples of the CAPTURE buffers. The control signal database points for which data are gathered are defined by the points passed to the CAPTURE buffers in the @Trip_History module of the .m6b Toolbox file for the turbine. The Trip Log file also contains alarms that occurred during the trip log period indicated by blue triangles on the time axis. (For the exact times of the alarm annunciations, Refer to the Alarm Historian Exception Report.) Each Trip Log file is stored in a directory named for the day (expressed in UTC time format) the trip event occurred. Multiple Trip Log files are stored in that day's directory if more than one trip event occurs per day. The Data Historian Service on the HMI maintains the 30 most recent Trip Log files; older Trip Log files are automatically deleted to conserve disk space. Older files can be manually relocated to another location to prevent their deletion and loss.

Hold List (Steam Applications) - Mark V and Mark VI The Hold List is required for the HMI to support Mark V controllers on systems that have Automatic Turbine Startup (ATS). ATS is used to set speed control targets and valve positions based on various inputs (such as steam temperatures and pressures, calculated valve stresses, turbine rotor stresses, and turbine shell stresses, metal temperatures, speed and operating mode). Turbine operating conditions can cause a hold, which prevents ATS from setting the speed or load target to a higher value. In the HMI, the Hold List display enables the user to view the current points on the Hold List and to override any or all hold points, if desired. Overriding a hold allows the ATS to advance its operating points as operating conditions permit. Note This program is used with Mark V and Mark VI controllers.
GEH-6126C Vol I HMI Operators Guide
Chapter 3 Display and Control (Command) Programs • 3-31
Example of a Typical Hold List
The CIMPLICITY Alarm Viewer displays the Hold List on the HMI. There is usually a separate CIMPLICITY Alarm Viewer for the Hold List to allow only the holds from a given unit on the display. Holds are not usually displayed on a regular alarm list. Note Refer to Chapter 2 and Appendix B for more information on alarm displays.
Hold List Rules The Hold List is maintained according to the following rules: •
A point that is picked up is entered in the Hold List as (0 - > 1).
•
Unacknowledged entries have an N character in the ACK field.
•
Acknowledged entries have a Y character in the ACK field.
•
A hold point whose state is a picked-up (logic 1) displays the ALARM state.
•
A hold point whose state is a dropped-out (logic 0) displays the NORMAL state.
•
A point that has been acknowledged is removed from the Hold List display.
•
A picked up hold point can be overridden by an operator using the Lock command button.
•
An overridden point displays Locked as the first part of their long name text.
•
An overridden point loses its override when it drops out (1 -> 0).
•
The Hold List displays the time of the last pickup or override, unit, acknowledge state, current state, override status, and the short and long name of each hold point in the list.
•
The text Hold displays in the drop number field and the CSDB offset displays in the reference field. The reference field is typically not displayed.
•
The Hold List program in , not , outputs a logic signal indicating that there are one or more active holds that have not been overridden. This point is named L68DW_ATS_HL. ATS and the turbine control use this signal to set speed, load, and valve position targets.

Data Area Description Unlike the Header and Legend, the point names and command targets in the Data Area scroll with the scroll bars. Demand Display updates only the visible points. The following sections in the Data Area provide information or require input: •
The Point Name field holds the control signal point name (or synonym) of valid unit database points. Entering the point name causes Demand Display to use the currently selected unit’s data, which is the unit listed in the Header. Entering the unit name with a colon before the point name, as in T2:{Pointname}, displays data from the requested unit. The Point Name field is 15 characters in length. Demand Display allows you to enter other text into this field for commenting and separating sections of points. Invalid point names are treated as text to allow for entering textual separations of the data.
•
The Value field contains point value information. This field updates once each second, is right justified, and can contain up to 10 characters. If the value is larger than 10 characters, 10 asterisks display. Enumerated state values display across both the Value field and the Units field. The Demand Display program centers the Enumerated state values across these fields and truncates them if they are over 17 characters long. A blank Value field indicates either of 2 conditions: –
The point information is invalid.
–
There is no data for the point in the Data Dictionary.
•
The Units field displays engineering units for valid point names exactly as found in the Data Dictionary. This field is blank for invalid point names, and indicates the engineering units for valid points. The Units field combines with the Value field to display the text for enumerated points.
•
The Command Target field is to the right of the Units field. It contains Unit Command Targets (buttons) for sending control commands to the unit.
Command Target Types Command Targets (Refer to figure Example of Point List Display) are essentially buttons that user select to perform the action identified on its label. There are three Command Target types: •
Immediate Action type sends a command to the control immediately without requiring further action. They typically perform an incremental change to the control, such as Raise or Lower. Note Immediate Action targets use black text on a red background. The text turns yellow if the feedback logic is supplied and met. Note Feedback logic is optional.
•
Arm/Execute type typically performs changes to the control state, such as Start and Stop. When selected, it opens the Execute Command dialog box to confirm execution. Selecting OK sends the command to the unit. Selecting Cancel cancels the command. Closing the dialog box cancels the command. Refer to figure Example of Arm/Execute Dialog Box. Note Arm/Execute targets use black text on a green background. The text turns yellow if the feedback logic is supplied and met. Note Requiring command confirmation before sending them to the unit helps prevent execution of false commands.

Target Text should indicate the Command Target’s action. Text appears black, but turns yellow if the associated feedback logic is supplied and the sense met. Allows two lines of up to eight characters per line. Text is automatically centered on the button. Unit command Point Name is the control signal pointname that receives the target’s value. Only command pointnames are allowed. They can be pushbutton, logics, or analog setpoints. Button Type defines which Command Target to use. For definitions, refer to Command Target Types. Value holds the value the Command target sends to the unit. Use the following guidelines (based on pointnames): A Pushbutton’s value is the number of scans to hold the pushbutton true. The minimum value is four scans. Logic States require a value of 1 or 0. Analog setpoints require a value in the engineering units specified for the command signal point. Value type determines how the Command Target sends the value to the unit: Set (=) sends the value from the value type to the unit. It is required for Pushbuttons and Logic States and optional for Analog Setpoints. Increment (+) adds the value in the value field to the current value of an Analog Setpoint and sends it to the unit. Decrement (-) subtracts the value in the value field from the current value of an Analog Setpoint and sends it to the unit.
Feedback Signal contains the feedback signal’s definition. Immediate Action and Arm/Execute button types can use feedback signals. Analog Setpoint button types cannot. Pointname is for the control signal point name of the feedback signal, which can only be logic point types. Sense can invert the sense of the feedback signal.
Other Options There are several other options available in the Demand Display program: •
Selecting Edit - Set Font displays the Windows Font dialog box. Select the font and color desired for the Demand Display screen. The selection applies to all Demand Display screens, except for the Command Targets where the colors are predefined.

Logic Forcing Display - Mark V and Mark V LM The Logic Forcing Display program can be used for monitoring and forcing a logic point. For example, during maintenance or troubleshooting it may be necessary to make the controller believe that a certain valve is in a particular position, as indicated by a limit switch. A simple approach is to use the controller Logic Forcing capability. The Logic Forcing Display has the following features: •
Ability to monitor multiple data points, both analog and logical.
•
Ability to change and maintain a logic state of the point (0 or 1) regardless of the sequencing driving the point.
•
Ability to add comment text and blank lines.
•
Ability to alter displays to conform to user needs.
•
Ability to monitor points in other controllers.
•
Ability to create, save and reuse displays for testing and special uses.
•
Ability to continuously scan the controller and add forced logic points to the end of the view list.
Note Mark IV uses the Operator Interface; Refer to GEK-83865 and GEK-83866 for this function. Mark V and Mark V LM support this utility. Mark VI uses the toolbox. Only qualified personnel knowledgeable about turbine control and protection should use the Logic Forcing functions. Improper use can adversely affect the control and protective features of the control system. Note This feature may not be available to operator or maintenance personnel.
Starting the Logic Forcing Display To Start the Logic Forcing Display From the Start menu, select Turbine Control Maintenance, Unit T#, then Logic Forcing Display. Or From the Windows desktop, click the Logic Forcing Display icon. The Logic Forcing Display opens an empty display and starts scanning the controller for forced logic points, adding the points to the display as they are found. Note Saving this display prompts the user for a new file name.

Logic Forcing Display Screen Window The Logic Forcing Display screen is made up of three main regions, the Header, the List View, and the Command Target area. Refer to figure Logic Forcing Display Example. •
The Header contains the unit name, site name, program title and time tag. The Header is in a non-scrolling region and cannot scroll off the window. The menu bar option View and the Header command toggles the Header on or off. The Header contains valuable process information and it is recommended that it remain visible at all times.
The Header time tag displays the controller time. If the Data Area is empty, contains no valid points, or the Data Area contains valid points but no data has been received from the controller, the time tag displays No Valid Data. A highlighted Header time tag indicates the oldest piece of data in the Data Area has not been updated for five seconds. •
The List View is composed of three columns, the Point Name, the Current Value from each processor, and the Engineering Units.
The List View scrolls and each of the columns is adjustable in width. If the column becomes too narrow to display all of the data, an ellipsis (…) appears on the right side of the column. The Current Value field is updated once per second from each controller processor. The time tag displayed in the Header reflects the time tag of the oldest piece of data displayed. Only the points visible on the screen are updated. There is no limit to the number of points that can be added to the point list. Unlike the Header, the information in the Data Area scrolls with the scroll bars. The Logic Forcing Display updates only the visible points in the List View. The Pointname field holds the Control Signal pointname (or synonym) of valid unit database points. Entering the pointname causes the Logic Forcing Display program to use the currently selected unit’s data, which is the unit listed in the Header. Entering the pointname of a non-logic point results in the display of the voted value instead of the value in the individual controllers. If a fully qualified point name is entered (in the form unitname:pointname) voted values of points from a different unit can be displayed (but not forced). Text other than a pointname can be entered for commenting and separating sections of points. Each column in the Value field displays the value in a processor. If the pointname is invalid or there is no data for the point in the Data Dictionary, this field remains blank. Forced points appear with a > character preceding the value. The Units field displays the Engineering units for valid pointnames. The text appears exactly as entered in the scale code table file. This field is blank for invalid pointnames, but indicates the units for valid points. •
The Command Target area appears on the right side of the Logic Forcing Display window. There are four Arm/Execute targets available for the Logic Forcing function. These targets are for forcing Logic signals to a state of 1 or 0, to unforce a single Logic signal, or to unforce all forced Logic signals. Arm/Execute targets appear green with black text and require a confirmation before sending the force or unforce signal to the controller.

Forced Variables using Control System Toolbox The controller has a feature called Forced Variables. This allows the maintenance technician using toolbox to set analog or logical variables to forced values. Variables remain at the forced value until unforced. Both compute and input processing respect forcing. Any applied forcing is preserved through power down or reboot of the controller, because forced variables in the controller are saved in NOVRAM. Logic Forcing is for offline software checkout and troubleshooting and should only be used in conjunction with proper lockout/tag out procedures. Forcing of protective functions is never permissible for an operating unit.

Appendix B Alarm Overview Introduction This appendix provides a general overview of turbine controller alarms viewed and addressed using the HMI. It is intended to assist the operator in understanding how to use the HMI for monitoring, using the features described in this document. The turbine controllers generate three types of alarms, which are viewed on the HMI or toolbox: Process, Hold List, and Diagnostic (Refer to figure Three Types of Alarms Generated by the Mark VI Controller).

Three Types of Alarms Generated by the Mark VI Controller
Note The information in this appendix applies specifically to the Mark VI controller. However, it should also apply to Mark IV, Mark V, and Mark V LM controllers, except in discussion of Control System Toolbox features.
Hold List Alarms (Steam Turbine Only) Hold List alarms are similar to process alarms with the additional feature that the scanner drives a specified signal True whenever any Hold List signal is in the alarm state (hold present). This signal is used to disable automatic turbine startup logic at various stages in the sequencing. Operators can override a hold list signal so that the sequencing can proceed even if the hold condition has not cleared. Note Refer to the Hold List section in Chapter 3.
GEH-6126C Vol I HMI Operators Guide
Appendix B Alarm Overview • B-1
Process Alarms Process Alarms are caused by machinery and process problems, and alert the operator by means of messages on the HMI screen. The alarms are created in the controller using alarm bits generated in the I/O boards or in sequencing. The user configures the desired analog alarm settings in sequencing using the toolbox. Process Alarms are generated by the transition of Boolean signals configured by the toolbox (for Mark VI) with the alarm attribute. The signals can be driven by sequencing or they can be tied to input points to map values directly from I/O boards. Process alarm signals are scanned each frame after the sequencing is run. In TMR systems, process signals are voted and the resulting composite diagnostic is present in each controller. A useful application for process alarms is the annunciation of system limit checking. Limit checking takes place in the I/O boards at the frame rate, and the resulting Boolean status information is transferred to the controller and mapped to Process Alarm signals. Two system limits are available for each process input, including thermocouple, RTD, current, voltage, and pulse rate inputs. System limit 1 can be the high or low alarm setting, and system limit 2 can be a second high or low alarm setting. These limits are configured from the toolbox in engineering units. There are several choices when configuring system limits. Limits can be configured as enabled or disabled, latched or unlatched, and greater than or less than the preset value. System out of limits can be reset with the RESET_SYS signal
Process (and Hold) Alarm Data Flow Process and Hold alarms are time stamped and stored in a local queue in the controller. Changes representing alarms are time stamped and sent to the alarm queue. Reports containing alarm information are assembled and sent over the UDH to the CIMPLICITY HMIs. Here the alarms are again queued and prepared for operator display by the Alarm Viewer. Note The operator or the controller can take action based on process alarms. Operator commands from the HMI, such as alarm Acknowledge, Reset, Lock, and Unlock, are sent back over the UDH to the alarm queue. There they change the status of the appropriate alarms. An alarm entry is removed from the controller queue when its state has returned to normal and it has been acknowledged and reset (Refer to figure Generating Process Alarms). Hold alarms are managed in the same fashion but are stored on a separate queue. Additionally, hold alarms cannot be locked but can be overridden.

Diagnostic Alarms Diagnostic Alarms are caused by equipment problems, and use settings factory programmed in the boards. Diagnostic Alarms identify the failed module to help the service engineer quickly repair the system. For details of the failure, the operator can request a display on the toolbox screen (Mark VI) or review the details in the HMI Alarm Display screen. The controller and I/O boards all generate diagnostic alarms, including the VCMI, which generates diagnostics for the power subsystem. The controller has extensive self-diagnostics, most that are available directly at the toolbox (for Mark VI). Diagnostic alarms can be viewed from the toolbox by selecting the desired board, clicking the right mouse button to display the drop-down menu, and selecting display diagnostics. A list of the diagnostic alarms for any I/O board can be displayed, and can be reset from the toolbox.
