PRODUCT INFORMATION
Product Overview
The General Electric IC697CPU780 is a Series 90-70 Processor Module for programmable logic controllers. It installs directly into slot 1 of rack 0. The unit uses a 16 megahertz 80386DX microprocessor for system operations. Boolean functions execute at a speed of 0.4 microseconds per function. The module supports floating-point math calculations for complex automation control tasks.
This processor module supports redundant hot standby architectures to prevent system downtime. In redundant setups, one CPU operates as primary while a second CPU acts as secondary. Control transfer occurs through bumpless switching within a single scan cycle. The architecture supports CPU synchronization, scan extension up to 20 milliseconds, and online repairs. System memory configurations range up to 512 kilobytes, with support for battery-backed RAM and non-volatile flash.
