Environmental Specifications

‑ Operating temperature: 0 ℃ ~ +60 ℃; RX7i fan tray is required for full‑range operation ‑ Storage temperature: −40 ℃ ~ +85 ℃ ‑ Relative humidity: 5%‑95% non‑condensing ‑ Installation location: Indoor control cabinet, IP20 protection class ‑ EMC compliance: IEC 61000‑6‑2 ‑ Certifications: CE, UL Class I Div 2 hazardous‑location certification

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. Supports hot‑standby redundant CPU configuration to achieve bumpless switch‑over upon primary‑CPU failure. Conformal‑coated PCB 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   ‑ FAULT: Hardware error, program fault 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 IC698CPE020‑JX into dedicated CPU slot of RX7i VME chassis and fasten module latch. Confirm IC698ACC701 lithium battery is properly seated.
3. Network and serial wiring comply with reference manual GFK‑2244. 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, perform redundancy synchronization and bumpless switch‑over validation test.
5. Replacement note: 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.
