Main Functions

1. Multi‑protocol communication stack processing: Executes Modbus‑TCP / Modbus‑RTU protocol, realizes bidirectional data exchange between excitation system and upper‑level automation system.
2. Process‑data upload: Transmits generator voltage, current, excitation current, running status, alarm and fault event data from main processor to DCS/SCADA system.
3. Remote command receiving & parsing: Receives remote set‑point, parameter modification and control instructions from upper system, forwards valid commands to main processor.
4. Communication link diagnosis: Detects link break, frame error and abnormal response, reports communication fault codes to main processor.
5. High‑speed data forwarding: Implements data transmission between VME back‑plane bus and physical communication ports, PPC380AE01 daughter‑board undertakes physical‑layer signal driving and conversion work.
6. Board‑level self‑diagnosis: Monitors on‑board power supply, VME link status and daughter‑board contact reliability; uploads hardware‑fault alarm 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 / daughter‑board contact fault / board hardware fault alarm

Installation & Wiring Requirements

1. Cut off cabinet total power before disassembly and assembly. Ensure PPC380AE01 daughter‑board is securely plugged onto UFC718AE01 mainboard; insert complete assembly into designated VME rack slot and lock front‑panel handles firmly. Hot‑swap is strictly forbidden.
2. Connect Ethernet cable and serial shielded twisted‑pair cables to corresponding ports on PPC380AE01; strictly follow communication wiring specification, complete shielding grounding 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 bus scan and signal‑point verification test before unit commissioning.
5. Replacement note: Cannot run independently; must match corresponding main‑processor hardware and full‑system firmware version; both UFC718AE01 mainboard and PPC380AE01 daughter‑board must be intact for normal communication function.
