Functional Description
DS200LSTCF1ACE is a Software PROM Set developed by GE under Mark V control system. The Software PROM Set stores firmware and operational parameters for the control processes. This ensures that the system operates correctly and efficiently according to predefined parameters and control logic.
System Time Synchronization Features
- Coordinated Operations: Time synchronization ensures that all actions, events, and logs across the control system are aligned. This is particularly important in complex systems where multiple processes need to work in harmony.
- Accurate Data Logging: Synchronized time allows for precise data logging, which is critical for diagnosing issues, performance monitoring, and regulatory compliance. Accurate timestamps ensure that events can be correlated correctly across different systems and devices.
- System Reliability and Safety: In safety-critical applications, such as power plants or manufacturing facilities, synchronized time helps prevent errors that could arise from time discrepancies. This enhances overall system reliability and safety.
- Network Coordination: For distributed control systems (DCSs) and other networked equipment, synchronized time is essential for coordinating communication and ensuring that commands are executed in the correct sequence.
- Global Time Source (GTS): A GTS, such as the IRIG-B time code signal or periodic pulse inputs, provides a highly accurate reference time. IRIG-B is a widely used time code format that delivers precise time information to connected devices.
- Network Time Protocol (NTP): NTP is a networking protocol designed for clock synchronization between computer systems over packet-switched, variable-latency data networks. It is commonly used in enterprise environments for general time synchronization needs.
- Precision Time Protocol (PTP): PTP, defined by the IEEE 1588 standard, provides more accurate time synchronization than NTP. It is particularly useful in environments where microsecond accuracy is required.
- GPS Time Signal: Global Positioning System (GPS) receivers can provide accurate time signals derived from satellite transmissions. This method is often used in remote locations or where network-based time sources are unavailable.
- Connecting to a GTS: The control panels receive time signals from a GTS, such as an IRIG-B source. This connection ensures that all panels are synchronized to the same precise time.
- Synchronizing Operator Interfaces:All computers with operator interfaces are set to the time provided by the GTS. This ensures that all human-machine interfaces (HMIs) display accurate and consistent time information.
- Integrating with Plant Equipment: The synchronization extends beyond the control panels to the rest of the plant equipment. Distributed control systems (DCSs) and other devices are also synchronized with the same GTS, ensuring overall plant coordination.

FREQUENTLY ASKED QUESTIONS
What is DS200LSTCF1ACE?
It is a Software PROM Set developed by GE
How is EPROM different from RAM and EEPROM?
EPROM- Non-volatile memory that retains data when power is off and can be erased using UV light for reprogramming. RAM- Volatile memory used for temporary data storage that loses its data when power is off. EEPROM- Non-volatile memory that can be electrically erased and reprogrammed without needing UV light, used for storing up-to-date application software and configuration data.
What role does EPROM play in turbine control systems?
EPROM in turbine control systems, such as GE's Mark V, stores the firmware and fixed data essential for the control algorithms and operational logic that manage the turbine's performance. This ensures reliable and consistent operation.
