Mechanical Data

‑ Weight: approx 0.34 kg ‑ Dimension: RX3i single‑slot CPU module form‑factor ‑ Handling note: ESD‑sensitive processor circuitry. Periodically inspect RTC lithium‑battery aging status. USB‑Host port is only for USB storage devices; direct PC programming via USB is not supported.

Main Functions

1. Main processing unit for RX3i system. Executes IEC 61131‑3 user logic and floating‑point arithmetic. Controls local and expansion‑rack I/O via dual PCI / serial backplane bus.
2. Multi‑protocol communication ports: Ethernet for SCADA host connection and Modbus‑TCP devices; RS‑232 / RS‑485 for Modbus‑RTU field instruments and multi‑PLC interconnection.
3. USB‑Host supports on‑site firmware upgrade, program backup and restoration without programming computer.
4. User program and data stored in non‑volatile flash without battery. RTC clock maintained by onboard lithium battery. Optional Energy Pack enables instant persistent data storage upon power failure.
5. Front‑panel LED indicators:   ‑ Green CPU OK: CPU hardware status normal   ‑ Red FAULT: Hardware / memory / configuration fault   ‑ Green RUN: User program executing   ‑ I/O FORCE: I/O force function active   ‑ Ethernet / COM1 / COM2: Communication activity status

Installation & Wiring Requirements

1. Cut off full rack power supply before replacement. CPU hot‑swap operation is strictly forbidden. ESD protection must be applied during module handling.
2. Insert IC695CPE310‑ABAB into RX3i universal backplane slot and engage locking latch. Install optional IC695ACC400 Energy Pack if required.
3. Network and serial wiring shall comply with GE RX3i hardware manual. Use shielded twisted‑pair cable for RS‑485 bus; install terminating resistor at bus end. Reliable protective ground connection is required.
4. After replacement: Power‑on rack power, check CPU OK / RUN / FAULT LED status. Download hardware configuration and user application program. Complete I/O mapping validation and all communication link tests.
5. Replacement note: Confirm firmware version V7.11. Check total backplane power‑supply load budget. Inspect RTC battery health. Full‑system commissioning test is mandatory before putting into service.
