Technical Overview
The GE IC697CPU731 is a single-slot central processing unit for the GE Fanuc Series 90-70 programmable logic controller platform. This module executes real-time control logic for machines, processes, and material handling systems. It houses an 80C186 microprocessor running at 12 MHz . The CPU provides 32 KB of battery-backed CMOS memory with a fixed allocation for user programs . A three-position mode switch on the front panel allows operators to control module operation . Three green LEDs indicate the CPU status, simplifying diagnostics . The module also includes a battery-backed calendar clock for time-stamping events and scheduling tasks .
This CPU communicates with I/O and smart option modules over the rack-mounted backplane using the VME C.1 Standard format . It supports up to 512 discrete I/O points in any mix and accommodates up to 8K analog I/O modules . The unit also includes one RS422/485-compatible serial port for programmer attachment, which you can connect to a PC via an appropriate converter .
