Main Functions

1. Execute core real‑time turbine control algorithms: speed control, load regulation, valve position closed‑loop calculation, protection logic and unit sequence control.
2. Exchange real‑time process data with VSVO, VTUR, VVIB, VTCC and other VME I/O boards through VME backplane bus.
3. Provide multi‑protocol external communication for data interaction with operator HMI, engineering workstation and plant DCS system.
4. Store event log, alarm information and trend data; support local serial port for firmware download and on‑site maintenance debugging.
5. On‑board self‑diagnosis: detect watchdog timeout, firmware integrity error, VME‑bus communication abnormality, Ethernet and serial‑port link failure; upload fault alarm status.
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 and turbine application code, check communication link status, perform full control‑loop commissioning test.
6. Replacement note: For TMR triple‑redundant system application, hardware consistency and firmware‑version matching of redundant controller boards shall be verified; full control‑loop simulation test mandatory before unit put‑into‑service.
