Series: Mark V
Function: Software PROM Set

Functional Description

DS200TCQAF1AFE is a Software PROM Set developed by GE. It is part of the GE Speedtronic Mark V control system. This PROM set is installed on specific control boards within the Mark V system to store essential software instructions, logic programs, and configuration data. It enables the control system to perform real-time monitoring, protection, and control tasks with high reliability and precision.

Product Features

• PROM devices provide non-volatile memory, allowing programmed information to remain stored when system power is removed. Within the Mark V system, programmed memory components are used to retain the software and logic required for specific control functions.
• The stored information enables the control hardware to execute programmed sequences, process system inputs, perform control calculations, and generate appropriate outputs.
• The Software PROM Set is therefore an important component for maintaining the programmed functionality of the Mark V system.
• The exact software and configuration stored in a PROM set must be compatible with the corresponding control board and the specific turbine application. Before replacement, the part number, software revision, and system configuration should be verified against the applicable GE documentation.

Software PROM Set Attributes

The programmed information stored in the PROM set can support various control-system functions, including:

• Execution of programmed control logic
• Processing of input and feedback signals
• Turbine sequencing and control
• Real-time monitoring
• Protection and alarm functions
• Decision-making based on operating conditions
• Generation of control outputs
• System configuration and application-specific logic
• Coordination between different control-system components

By providing fixed, non-volatile storage for programmed information, the PROM set supports consistent execution of the control software and contributes to the reliable operation of the Mark V control system.

Overview of the Speedtronic Mark V Control System

The GE Speedtronic Mark V is a digital turbine control system developed for the monitoring, protection, and control of gas and steam turbine applications. It represents a later generation of GE's Speedtronic turbine control technology and builds on the design concepts established in earlier systems, including the Speedtronic Mark IV.

The Mark V architecture incorporates microprocessor-based control, distributed I/O, diagnostic capabilities, and fault-tolerant design features. These technologies allow the system to continuously monitor turbine operating conditions and execute programmed control and protection logic.

Upgraded Microprocessors

The Mark V system uses microprocessor-based control hardware to execute turbine control algorithms and application logic. Improved processing capabilities allow the system to handle control calculations, signal processing, sequencing, and monitoring tasks required for modern turbine applications.

The use of programmable digital controllers also allows control functions to be implemented through software rather than relying solely on fixed hardware logic.

Increased I/O Capacity

The Mark V architecture supports a broad range of input and output (I/O) signals from turbine instrumentation and auxiliary equipment.

Depending on the turbine application, the system can interface with signals associated with:

• Temperature
• Pressure
• Speed
• Position
• Vibration
• Flow
• Valve position
• Generator parameters
• Other turbine operating measurements

The modular I/O architecture allows the control system to accommodate the instrumentation and control requirements of different turbine configurations.

SIFT – Software-Implemented Fault Tolerance

• One of the important design concepts associated with the Mark V system is SIFT (Software-Implemented Fault Tolerance).
• SIFT uses software-based techniques to identify discrepancies and faults within the control system. The architecture supports fault detection and appropriate handling of abnormal conditions, helping maintain reliable control-system operation.
• Fault-tolerance features are particularly important in turbine control applications because the control system must continuously monitor critical operating parameters and respond appropriately when abnormal conditions occur.

Advanced Diagnostics

The Mark V incorporates diagnostic capabilities designed to help operators and maintenance personnel identify control-system problems.

Diagnostic functions can provide information about:

• I/O signal conditions
• Controller status
• Hardware faults
• Communication problems
• Sensor abnormalities
• System alarms
• Control-system failures

These diagnostic capabilities can simplify troubleshooting and help maintenance personnel identify potential problems before they result in extended equipment downtime.

Standardization and Modularity

• The Mark V system uses a modular architecture consisting of controllers, I/O boards, terminal boards, memory components, communication interfaces, and other hardware modules.
• This modular approach simplifies maintenance because individual components can be inspected, tested, or replaced when required. Standardized hardware and software structures also help support spare-part management and system maintenance.
• The use of individual boards and programmable memory components, allows specific control functions to be implemented according to the requirements of the turbine application.

Improved Operator Interface

The Mark V system provides operator interface capabilities that allow personnel to monitor turbine operating conditions and system status.

Through the operator interface, users can access information such as:

• Turbine operating parameters
• Alarms and events
• System status
• Diagnostic information
• Control-system conditions
• Process measurements
• Protection status
