Functions
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 communica-
tions functions. It communicates with the PLC CPU
over the backplane and can access user and system
data using extensions to the powerful MegaBasic lan-
guage. 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 ex-
pansion memory up to 512 Kbytes.

Dual tasking allows running a MegaBasic program at
the same time the PCM is used as a communications
interface. Operation of the module may be initialized
by a pushbutton or by an attached PCM development
system. The status of the PCM is indicated by three
green LEDs on the front of the module.
