The GE IS200VCMIH2B is a VME bus master controller board in the Mark VI turbine control system, facilitating communication between I/O boards, control modules, and protection modules via the IONet. It supports both simplex and TMR configurations, with TMR models communicating across three I/O channels and other control modules.
Equipped with a Texas Instruments TMS320C32 32-bit DSP, it features dual-port memory, SRAM (64k×32), and flash memory (128k×8). Communication includes 10 Base2 Ethernet, VME bus transfers, an RS-232C serial port, and a parallel port. Mounted in slot one of the Central Control Module, it uses Software Implemented Fault Tolerance voting for input data, ensuring reliability in gas, steam, and wind turbine applications.
Features:
Dual Configuration Support: Operates in simplex or TMR systems, adapting to redundancy needs.
Robust Communication: Integrates Ethernet (IONet), VME bus, serial, and parallel ports for seamless data transfer between modules and I/O racks.
SIFT Voting: Enhances fault tolerance by voting on input data from IONet connections, ensuring accurate data transmission to controllers.
Powerful Processing: Uses a 32-bit DSP with dedicated memory for efficient signal processing and real-time control.
Comprehensive Diagnostics: Includes a watchdog timer (150 ms) for processor stall detection and redundancy-informed alarms.
Durable Hardware: Features a front faceplate with LEDs, connectors (IONet, serial), and components like FPGAs, transformers, and integrated circuits, designed for industrial resilience.
Mark VI Integration: Critical for Speedtronic systems, supporting expanded turbine applications beyond earlier Mark V capabilities.
