Functional Features Super large‑capacity memory, high‑speed logic computation, dual independent Ethernet interfaces, abundant industrial protocol support, high‑density I/O management, detailed system diagnostic logging, online program modification and remote maintenance.
Application Scenarios Large‑scale process plant main control, complex production line control, multi‑device interlocking system, heavy‑communication‑load RX3i control cabinet.
Performance Parameters High‑speed deterministic scan cycle Dual‑network physical isolation function Mass fault and event data storage Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i plug‑in rack module Front‑panel multi‑group comprehensive status LED indicators Dual RJ45 Ethernet sockets and RS232 serial port Backplane gold‑finger bus contact Internal high‑performance processor and large memory array Mechanical locking latch
Working Principle In each scan cycle, CPU synchronizes I/O image table through RX3i backplane bus. Executes complex user application logic from internal memory. Sends output control commands to field I/O modules. Dual Ethernet ports realize isolated control network and monitoring network data interaction. Serial port provides local programming debugging interface. All alarm and diagnostic events are saved in non‑volatile memory.
Installation Requirements Insert module into CPU dedicated slot on RX3i main rack. Complete reliable cabinet protective grounding. Plan IP address for two Ethernet ports reasonably. Deploy shielded twisted‑pair network cables. Power‑off rack before module replacement, hot‑swap forbidden. Ensure cabinet ventilation heat dissipation without blockage.
Usage Notes Total configured I/O points cannot exceed 2048 limit. Regularly back up complete project program and configuration. Strictly separate control network from external public network. Retrieve diagnostic log for system failure analysis. Forbid on‑site disassembly. Keep away from corrosive gas, liquid splash and oil mist.
