General Electric IC693PCM311 Programmable Coprocessor Module

The GE IC693PCM311 Programmable Coprocessor Module (PCM) is a high-performance coprocessor specifically designed to expand the capabilities of the GE Fanuc Series 90-30 PLC system. It operates as an independent processing unit within the PLC rack, capable of executing complex algorithms, handling advanced communications, and managing demanding data processing tasks that would otherwise burden the main PLC CPU.

Built around a fast Intel 80C186 processor, the IC693PCM311 is engineered to allow users to develop and deploy custom programs using C, C++, or BASIC. It supports two serial ports (RS-232/RS-485), making it ideal for communicating with a wide variety of external devices—including drives, sensors, printers, bar code readers, HMIs, and legacy equipment.

This flexible module allows plant operators and system integrators to extend the functionality of their Series 90-30 PLC without needing expensive controller upgrades, offering significant benefits in applications such as protocol conversion, advanced control, data logging, and OEM machinery customization.
