Product Details 

IC698CRE040‑HN is the high‑performance hot‑standby redundant CPU for GE PACSystems RX7i VME64 automation platform, built upon 1.8GHz Pentium‑M industrial processor, specially designed for high‑availability industrial control scenarios requiring uninterrupted operation.

This redundant CPU is equipped with 64MB battery‑backed RAM and 64MB non‑volatile flash memory. User logic programs, hardware configurations, register data and symbolic variables can be persistently saved. The typical logic scan rate reaches 0.024ms per 1000 boolean contacts‑coils, delivering fast real‑time control response for complex industrial projects.

Two independent 10/100Mbps Ethernet ports support SRTP, Modbus TCP, EGD and SNTP time‑sync. RS232 and RS485 serial ports support Modbus RTU and SNP protocols. Built‑in web server and FTP function support up to 16 concurrent remote connections for monitoring, diagnosis and firmware upgrade.

For hot‑standby redundant configuration, this CPU must pair with IC698RMX016 redundant memory exchange module. Runtime data synchronizes continuously between primary and standby CPU. When main CPU fails, system completes automatic switch‑over within less than 1ms without stopping field production, greatly improving system reliability for critical production sites.

It supports multiple IEC standard programming languages, up to 512 program blocks, and is fully compatible with Series 90‑70 I/O modules and most third‑party VME64 modules. Online test‑edit allows program modification without stopping runtime. Front‑panel multi‑color LED indicators show CPU running status, fault alarm and each communication link condition for fast on‑site troubleshooting.

It adopts standard VME64 single‑slot slide‑in plug‑in structure, easy for installation and replacement. Widely deployed in power, petrochemical and other critical industries, applied for maintenance, upgrade and spare‑part replacement of old RX7i hot‑standby redundant PAC control systems.
