Main Functions

1. Multi‑protocol communication processing: Executes Modbus‑TCP / Modbus‑RTU protocol stack, realizes bidirectional data interaction between excitation system and external automation system.
2. Process‑data upload: Transmits generator voltage, current, excitation current, system status, alarm and fault event data from main processor to upper‑level DCS/SCADA system.
3. Remote command receiving & parsing: Receives remote set‑point commands, parameter modification commands and control instructions from upper system, forwards valid commands to main processor.
4. Communication link diagnosis: Detects communication link interruption, frame error and abnormal slave‑station response, reports communication fault codes to main processor.
5. Real‑time data forwarding: Implements high‑speed data transmission between VME back‑plane bus and external communication physical ports.
6. Board‑level self‑diagnosis: Monitors on‑board power supply, communication chip and VME link status; uploads hardware‑fault alarm information to UNITROL6000 system.
7. On‑board multi‑LED status indication
   • Green LED：Board power supply normal, board logic running healthy
   • Yellow LED：External communication port data transmission active
   • Red LED：Communication‑link fault / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Insert UFC718AE01 into designated VME rack slot and lock front‑panel handles firmly. Hot‑swap is strictly forbidden.
2. Connect Ethernet cable and serial communication shielded cables to corresponding ports; strictly follow communication wiring specification, complete shielding grounding processing for communication cables to restrain electromagnetic interference.
3. Cabinet protective grounding must comply with ABB AC800‑PEC / UNITROL6000 system grounding specification.
4. After replacement, verify full‑system firmware compatibility with main processor board; download matching communication configuration parameters; perform communication link test and data point verification before unit commissioning.
5. Replacement note: Cannot run independently; must match corresponding main‑processor hardware and full‑system firmware version.
