GE Fanuc IC697PCM711X PCM Module

Core Performance & Industrial Application

The GE Fanuc (Emerson) IC697PCM711X is a single-slot programmable coprocessor module (PCM) for the Series 90-70 PLC rack.

It runs an 80C186 at 12 MHz with dual-tasking MegaBasic for operator interface, real-time computation, data acquisition and communications.

It carries up to 96 KB battery-backed CMOS logic and data memory on board, expandable to 512 KB optional memory.

Two serial ports support RS-232 or RS-422/RS-485 at 9.6 Kbaud simultaneous or up to 19.2 Kbaud individually, using CCM2 protocol.

It accesses PLC user and system data over the backplane without CPU application changes, with a real-time calendar clock synced to the PLC.

It is used as spare replacement in legacy 90-70 computing and data communication racks.
