Product Overview
The GE Fanuc IC697PCM711 Coprocessor Module is a single-slot programmable coprocessor designed for the Series 90-70 PLC family. It extends system capability by offloading computation, data handling, and serial communications from the main CPU. The module supports user programs (MegaBasic), provides serial connectivity for external devices, and offers expandable memory with battery-backed retention—making it suitable for systems requiring additional processing, data acquisition, or protocol bridging without replacing the primary CPU.
Key Features
-
Single-slot programmable coprocessor for Series 90-70 systems

-
Two configurable serial ports (RS-232 / RS-422 / RS-485) for external device interfacing
-
Onboard user memory with optional expansion capability
-
Battery-backed CMOS memory for program and data retention
-
Software-configurable (no jumpers or DIP switches) for simplified setup
-
Low backplane current draw and compact rack mounting
-
Front-panel LEDs for status and diagnostics
