Working Principle CPU refreshes I/O image table through RX3i backplane bus in each scan cycle. Executes user logic program stored in internal memory. Output control commands to field I/O modules. Dual Ethernet ports realize separated communication for control network and upper‑monitoring network. Serial port serves for local programming and debugging. All fault events are saved in internal non‑volatile memory.
Installation Requirements Insert module into CPU dedicated slot of RX3i main rack. Complete cabinet protective grounding. Reasonably plan two Ethernet IP addresses. Use shielded twisted‑pair network cables. Power‑off rack before module replacement, hot‑swap not supported. Ensure cabinet ventilation and heat dissipation.
Usage Notes Total I/O quantity shall not exceed 1024 points. Regularly back up full project configuration. Isolate control network from public network. Read fault log when system abnormality occurs. Forbid on‑site disassembly. Keep away from corrosive gas, liquid splash and oil mist.
