Product Title & Description

Model: IC698CRE030 The GE Fanuc IC698CRE030 is a hot-standby redundant CPU module for the PACSystems RX7i VME64 automation platform. Powered by a 600MHz Pentium‑M processor, it is engineered for high-availability industrial control systems that demand uninterrupted operation. It executes real-time control logic, manages backplane I/O data exchange and multi-network communications, widely deployed in power generation, oil & gas, petrochemical and large continuous process plants, eliminating single-point controller failure risks for critical processes.

IC698CRE030

Core Product Overview

IC698CRE030 is the redundant central processing unit of GE PACSystems RX7i series. It supports HSB (Hot Standby Redundancy) architecture, paired with a secondary identical CPU. Synchronization of program, variable data and I/O states is maintained continuously between primary and standby controllers. If the primary CPU fails, seamless failover to standby CPU happens without process shutdown. This module features 64 MB battery-backed user RAM plus 64 MB non-volatile flash memory to retain application programs and configuration data after power loss. It communicates with I/O and intelligent option modules via the RX7i VME64 backplane. Dual 10/100Mbps Ethernet ports and multiple isolated serial interfaces support programming, HMI connection and fieldbus communication. It supports multiple IEC 61131-3 programming languages including Ladder Diagram, Structured Text, Function Block Diagram and C language for complex algorithm development. Built-in diagnostic functions continuously monitor CPU health, memory status, backplane and redundancy link quality.

Quality Control Procedures

GE PACSystems modules comply with ISO9001 and IEC 61131-2 industrial control standards.

1. Component Incoming Inspection: CPUs, memory chips, PCBs and communication ICs are sourced from approved vendors and 100% screened before assembly.
2. Automated Assembly & Serial Traceability: SMT assembly and soldering are automated. Unique serial number enables full lifecycle traceability.
3. Full Functional & Redundancy Test: Every finished module undergoes memory verification, Ethernet/serial communication test, logic execution test and redundancy synchronization simulation.
4. Environmental Stress Screening: Batch samples go through temperature cycling, vibration, EMC and power cycle tests to validate stability for critical industrial sites.
5. Final Inspection & Packing: Units passing all tests receive visual inspection, anti-static packaging and factory test certificates before shipment.

Frequently Asked Questions (FAQ)

Q1: What software is used to program ? A1: Proficy Machine Edition (PME), supporting IEC 61131-3 standard programming languages.

Q2: What is hot standby redundancy? A2: Two CPUs run in parallel. The standby controller continuously synchronizes all data with primary. When primary fails, the standby takes over control automatically with minimal disruption to the process.

Q3: Does the module retain program after power loss? A3: Yes. Application program and hardware configuration are stored in non-volatile flash. Runtime variables are preserved via battery-backed RAM.

Q4: What rack does use? A4: It installs in PACSystems RX7i VME64 rack, typical model IC698CHS009.

Q5: What is the warranty for original ? A5: Original GE module carries standard 12-month factory warranty against manufacturing defects under proper installation and operating conditions.

Installation & Configuration Guide

7.1 Pre-installation Preparation

Verify part number and inspect module for physical damage. Prepare RX7i VME rack, RMX redundancy module, shielded Ethernet/serial cables, backup battery and Proficy Machine Edition software. Cut off rack power before handling module. Wear ESD protection to avoid electrostatic damage. Confirm firmware compatibility between primary and standby CPUs for redundancy.

7.2 Installation Steps

Insert into designated CPU slot on RX7i VME rack and secure the module fasteners. Install the second identical CPU for redundant pair. Wire redundancy link between two CPUs via RMX module. Connect Ethernet and serial cables following GE wiring specifications, properly ground cable shields at cabinet side. Double-check backplane power supply rating and all connections. Reserve sufficient airflow clearance for heat dissipation.

7.3 System Configuration & Commissioning

Launch Proficy Machine Edition and add dual CPUs in hardware configuration. Enable HSB hot standby redundancy and configure synchronization parameters. Download project to primary CPU and perform automatic data synchronization to standby CPU. Power up rack and verify CPU RUN, REDUNDANCY and FAULT LED indicators. Conduct redundancy switchover test by forcing primary CPU fault to confirm seamless failover. Record switchover performance and commissioning logs.

7.4 Maintenance & Precautions

Regularly inspect backup battery health, fan operation and module temperature during planned outages. Keep cabinet clean and free of dust and corrosive gas. Check redundancy link cable integrity periodically. Do not open module housing. If redundancy sync failure occurs, verify firmware version, RMX module status and synchronization wiring before replacing the CPU.
