Description

Product Description

The IC697PCM711 is a dedicated programmable coprocessor module engineered for the GE Fanuc Series 90-70 PLC platform. It is intended to execute computation-intensive or time-sensitive tasks independently of the main CPU, improving overall system responsiveness and determinism.

Built around an Intel 80C186 processor running at 12 MHz, the module provides substantial local processing capability and supports concurrent task execution. A user-developed MegaBasic application can run in parallel with communication services, making it suitable for advanced data handling, operator interface logic, and custom control strategies.

The module communicates with the host PLC via the backplane and operates autonomously once deployed, without requiring continuous CPU intervention. Multiple modules can be installed within the same rack for distributed processing architectures.
