Main Functions

1. Run turbine‑specific application control logic, perform sequence control, load‑setpoint calculation and auxiliary interlock logic processing for Mark VI / EX2100 system.
2. Provide multi‑protocol external communication interface, realize data interaction with HMI workstation, DCS system and third‑party field devices.
3. Exchange real‑time process data with VSVO, VTUR, VVIB and other VME I/O processor boards through VME backplane bus.
4. Store trend data, event log and alarm records; support local serial port debugging and firmware download.
5. On‑board self‑diagnosis: detect watchdog timeout, firmware check‑sum error, VME‑bus communication abnormality, Ethernet and serial‑port link failure; upload fault alarm to turbine main controller.
6. LED status indication:   ‑ Green LED：Board power supply normal / RUN status   ‑ Yellow LED：Communication port activity indicator   ‑ Red LED：Module FAIL / fault alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB board.
2. Insert board into designated VME slot, secure panel locking screws; ensure VME backplane contact is reliable.
3. External Ethernet and serial‑port wiring strictly follow GE Speedtronic Mark VI wiring manual; communication cables adopt shielded twisted‑pair, strictly separated from high‑power cables; connect shielding to dedicated ground terminal.
4. Complete protective grounding according to GE system specification.
5. After replacement: verify VME rack power‑on status, download matching firmware, check communication link status, perform application logic verification test before commissioning.
6. Replacement note: For TMR triple‑redundant system application, hardware consistency and firmware version matching of related redundant boards shall be verified; full logic‑loop simulation test mandatory before unit put‑into‑service.
