Product Details

IC697CPX928‑FE is the high‑end high‑speed CPU processor for GE Fanuc Series 90‑70 PLC platform, adopting 96MHz Intel 80486DX4 32‑bit processor, designed for large‑scale complex industrial automation control projects.

This CPU is equipped with 6MB lithium‑battery‑backed RAM and 256KB non‑volatile flash memory. User logic programs, register data and system hardware configurations can be reliably preserved after power‑off. The replaceable lithium battery IC697ACC701 keeps RAM data for up to six months without rack power supply.

It delivers fast logic execution performance, typical scan speed reaches 0.4 microseconds per boolean function. It supports up to 12 thousand mixed discrete I/O points and 8 thousand analog channels, and fully supports 32‑bit floating‑point calculation for complex process algorithm operations.

Three serial ports are integrated on the module. One RS232 and two RS485 interfaces support SNP, Modbus RTU and Genius bus protocols, connecting HMI, remote I/O stations and third‑party serial field devices. The hardware run‑stop switch on front panel can manually control CPU running status. Seven independent LED indicators show system operation, fault alarm and communication link status for fast field troubleshooting.

It supports multiple programming languages, compatible with Series 90‑70 whole‑series I/O modules, Genius remote I/O and various communication coprocessor boards. It adopts single‑slot slide‑in plug‑in installation inside the 90‑70 rack. It is widely used in power, petrochemical and heavy‑industry sites, applied for maintenance, upgrading and spare‑part replacement of old large‑scale Series 90‑70 PLC automation systems.
