GE Fanuc IC697MEM715B Programmable Coprocessor Module

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.

IC697MEM715 is configured as a daughter board and is placed in the same slot as the module in which it operates. Memory of the base board and the daughter board are supplementary. In the event of power loss, memory is retained by the battery on the base board housing. Logic program memory is repeatedly error-checked by the PLC CPU as a background task by way of checksum routine. When power is cycled and during hard or soft resets, the PCM error automatically checks storage memory. IC697MEM715 does not require an additional slot for configuration, and it is adjustable for storage of the program and data.

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.
