Performance Parameters Deterministic PLC scan‑cycle execution performance. Non‑volatile persistent storage for fault‑event records. Shock and Vibration: Complies with IEC 60068 industrial environmental standard
Material Composition Module housing: Flame‑retardant industrial plastic PCB substrate: FR‑4 high‑temperature printed‑circuit material Bus contact fingers: Gold‑plated copper alloy Internal components: Industrial‑grade processor chip and memory integrated circuits
Structural Characteristics Standard RX7i plug‑in rack module form‑factor. Front‑panel multi‑LED indicators for RUN, STOP, FAULT and communication activity status. RJ45 Ethernet connector and RS485 screw terminal block. Gold‑plated backplane bus contact fingers. Internal high‑performance processor and memory chip assembly.
Working Principle The CPU refreshes the global I/O image table through chassis backplane bus in every scan cycle. It executes user logic stored inside internal memory. Output control commands distribute to corresponding field I/O modules. On‑board communication ports exchange data with HMI, SCADA host and programming workstation.
Installation Requirements Insert module into dedicated CPU slot of RX7i main chassis. Implement reliable cabinet protective earthing. Configure network IP address and serial‑port parameters via programming software.
Usage Notes Total configured system I/O quantity cannot exceed rated maximum of 8192 points. Back up user program and hardware configuration files on a regular basis. Diagnose system faults using front‑panel LED indicators and stored fault logs.
