Mechanical Data

‑ Weight: approx 0.80 kg ‑ Dimension: RX7i standard single‑slot VME module form‑factor

Main Functions

1. Executes IEC‑61131‑3 user control logic, floating‑point calculation, processes local and remote I/O data over VME backplane bus. Supports online program modification without stopping controller operation.
2. Dual‑port embedded Ethernet enables program download, SCADA/HMI connection, EGD peer‑to‑peer data exchange and Modbus‑TCP third‑party device communication. Internal network switch eliminates external hub for dual‑Ethernet setup.
3. HSSB fiber‑optic redundancy link synchronizes full program, variable and I/O state between primary and standby CPU, realizes bumpless hot‑standby fail‑over for safety‑critical applications. The ‑EE conformal‑coated hardware improves reliability under harsh plant ambient conditions.
4. Front‑panel LED indicators:   ‑ OK: Module power‑on self‑test passed   ‑ RUN: CPU executing user application logic   ‑ LAN1 / LAN2: Corresponding Ethernet port link‑activity status   ‑ SYNC: Redundancy HSSB link synchronization status   ‑ FAULT: Hardware error, program fault, redundancy loss or battery‑low warning

Installation & Wiring Requirements

1. Cut off full rack power supply before installation or replacement. Hot‑swap is not permitted. Apply ESD protection during module handling.
2. Insert IC698CRE030‑EE into dedicated CPU slot of RX7i VME chassis and fasten module latch. Confirm IC698ACC701 lithium battery is properly seated. Connect multi‑mode HSSB fiber cable between primary and standby CPU redundancy ports; respect fiber minimum bending radius.
3. Network, serial and fiber cabling comply with reference manual GFK‑2438W. Use shielded CAT5e cables for Ethernet communication. Reliable protective‑ground connection for rack chassis is mandatory.
4. After replacement: Power‑on rack power and check front‑panel LED status. Download hardware configuration and user application. Verify real‑time clock, battery status, Ethernet IP setup, EGD data exchange and serial‑port communication. For hot‑standby redundant system, confirm HSSB SYNC LED status, perform redundancy synchronization and bumpless switch‑over validation test.
5. Replacement note: Primary and standby CPU firmware versions must be matched. Monitor lithium‑battery aging periodically to prevent loss of RAM program and data. Fan‑tray must be functional for CPU operation at elevated ambient temperature. Full‑system commissioning test is mandatory before putting into service.
