Product description

The Programmable Coprocessor Module (PCM) is a Coprocessor to the PLC CPU. It can be programmed to perform operator interface, real time computations, data storage, data acquisition and data communications functions.

It communicates with the PLC CPU over the backplane and can access user and system data using extensions to the powerful MegaBasic language. No application program support is required in the PLC CPU. Many PCMs can be supported in a single IC697 PLC system and each can accommodate an optional expansion memory up to 512 Kbytes.

The PCM can operate with or without an expansion memory daughter board. The base memory on the PCM board has up to 95 Kbytes user memory. The expansion memory daughter board permits expansion of program/data memory by 64, 128, 256 or 512 Kbytes. The battery which supports this memory is located on the base board housing as shown in figure 2.

Batteries A lithium battery (IC697ACC701) is installed as shown in figure 2. This battery maintains user memory when power is removed. Be sure to install the new battery before removing the old battery. If during power-up diagnostics a low battery is detected the Module OK LED (top) will not stay on. Specific indication of a low battery state is detailed in the PCM Support Software User’s Manual.
