DS200TCCAF1ADD is a Software PROM Set manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Control Systems. The Mark V system is designed to boost unit reliability by employing three redundant control processors. This innovative triple modular redundant (TMR) setup ensures the safe operation, control, and protection of a unit even if one of its control processors fails. With this design, a single control processor can undergo maintenance and repair without necessitating a complete turbine shutdown.

  • Within the Mark V Control System, each Control Processor (R, S, and T) and Communication Processors (C and D) have their own Control Signal Database (CDB). These databases store control signals crucial for governing, safeguarding, and monitoring the turbine through the Control Sequence Program (CSP).
  • Connected interfaces like I, BOI, and remote devices interfacing via MODBUS or GSM can access vital information such as signal names, values, and engineering units from these CDBs.
  • Every CDB resides in the Random Access Memory (RAM) on the SDCC (Drive Control Card) within each Mark V Control and Communication processor. Notably, the Control Signal Databases on the control processors are identical but kept separate, containing the same signal values.
  • Additionally, other signal databases distributed across the Mark V system, like those on TCQA and TCEA cards, serve distinct yet related functions compared to the Control Sequence Program, using their signal databases. Control processors extract necessary signal values from these databases and copy them into the Control Signal Database.
  • Signals not transferred to the CDB remain inaccessible to both the Control Sequence Program and Mark V Interfaces. The microprocessors within the SDCC execute the Control Sequence Program using only the control signals and their respective values stored in the Control Signal Database on that specific SDCC card.
  • Signals within the Control Signal Database are of paramount importance as the CSP primarily manages turbine unit control and protection. Understanding these control signals is crucial when interpreting the CSP, especially regarding sequencing logic.
  • Modifications to the CSP often require introducing new signals into the Control Signal Database. This process essentially involves assigning names to spare signals within pre-existing memory locations in the SDCC RAM, simplifying the CSP development by avoiding the complex task of addressing signals by their memory locations.
