Product Function Description

IC698CRE040 is the high‑performance hot‑standby redundant CPU processor of GE Fanuc PACSystem RX7i VME‑based PAC platform。

This module adopts 1.8GHz Pentium‑M industrial processor, equipped with 64MB RAM and 64MB flash memory, provides powerful real‑time logic operation, floating‑point calculation and data storage capacity. It supports multiple IEC‑61131‑3 programming languages, can execute complex continuous‑process control logic for large industrial sites。

As a redundancy‑enabled CPU, it can build hot‑standby redundant control system by pairing with another IC698CRE040 and IC698RMX016 memory‑exchange module. The standby CPU keeps synchronizing user program, variables and running status from primary CPU, realizes bumpless switchover when main CPU fails, greatly improves system reliability for critical production processes。

Dual independent Ethernet ports can realize network redundancy configuration, supports EGD real‑time data exchange, Modbus‑TCP client/server communication. Serial ports are used for local programming, debugging and firmware upgrade. Built‑in web‑server function allows remote status browsing and simple diagnosis via browser。

This CPU is backward compatible with Series 90‑70 I/O modules and standard VME third‑party modules, convenient for upgrade and reconstruction of old GE automation sites. All configuration and programming work is completed via Proficy Machine Edition software.

Product Details

Standard VME form‑factor plug‑in CPU module, industrial‑grade anti‑interference hardware design, suitable for complex electromagnetic‑interference environment of factory and power‑plant sites. This legacy RX7i redundant CPU has been discontinued by original manufacturer, mainly used for old‑equipment overhaul and spare‑part replacement. Please pay attention to firmware version consistency of primary‑standby CPU and matching redundancy‑link module before commissioning. Strict ESD protection shall be adopted during installation.
