Main Functions

1. Dual redundant IONet Ethernet communication bridge between main CPU controller and all I/O packs in rack.
2. Transmit field process measuring data, protection interlock signals and channel fault diagnostic messages between controller and I/O modules.
3. Distribute high‑precision SYNC time‑synchronization signal to ensure multi‑I/O‑channel sampling time consistency for turbine fast‑loop control.
4. Hardware link diagnosis for Port A / Port B IONet channel, detect cable break, link down and communication abnormality.
5. On‑board self‑diagnosis: detect daughter‑board hardware fault, mezzanine connector loose contact, report fault status to main controller.
6. Front‑panel LED status indication:
   • Green ONLN LED：Module power‑on and link normal
   • Yellow MOD LED：IONet bus communication active
   • Red LED：Communication loss / hardware 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. Align and insert PMCI mezzanine board fully onto designated CPU board connector, fasten fixing screws to avoid poor contact.
3. Connect IONet network cables and SYNC synchronization cable strictly follow GE Mark VIe wiring manual; separate network cables from high‑power cables to reduce interference.
4. Complete protective grounding according to GE Speedtronic system specification.
5. After replacement: verify dual‑port IONet link status, check time‑sync signal quality, download controller configuration, validate full‑I/O‑rack data exchange before commissioning.
6. Replacement note: Firmware version consistency must be confirmed; both A/B channel communication function test is mandatory after swap.
