GE IC693PCM331 Programmable Coprocessor Module

Product Introduction

The GE IC693PCM331 Programmable Coprocessor Module is a powerful add-on processor designed for the GE Fanuc Series 90-30 PLC system, providing advanced computing capability for tasks that demand more than the main CPU’s resources.
It enables users to run custom applications, perform complex data processing, and communicate with external devices using multiple industrial protocols.
The module features an embedded 80386EX microprocessor and generous memory, allowing sophisticated control algorithms, data logging, and high-speed calculations without affecting the PLC’s primary scan time.
Its single-slot architecture makes it a space-efficient solution for plants and OEM equipment where high-performance control and data management are critical.

Product Specifications

Applications

• Advanced Data Processing – Performs statistical analysis, complex math calculations, and large-scale data manipulation in real time.

• Custom Protocol Conversion – Acts as a gateway between the PLC system and third-party devices by running custom communication protocols.

• High-Speed Machine Control – Handles motion control or high-speed logic operations offloaded from the main CPU.

• Data Logging & Storage – Captures and stores large volumes of process data for quality tracking and historical analysis.

• Embedded OEM Solutions – Suitable for machine builders needing custom embedded logic within a standard PLC rack.

• Process Optimization – Executes advanced algorithms for predictive maintenance or energy management.

Advantages

• Offloaded Processing – Frees the main PLC CPU for critical logic tasks by executing compute-heavy functions on the coprocessor.

• Flexible Programming – Supports high-level programming in C or C++, enabling creation of custom applications and algorithms.

• Multi-Protocol Support – Dual serial ports with RS-232/RS-485 allow integration with diverse industrial networks and legacy equipment.

• Expandable Memory – Ample SRAM and flash memory for large programs and data storage.

• Seamless Integration – Fits directly into a Series 90-30 rack without additional power or wiring.

• Industrial Durability – Built to operate reliably in environments with electrical noise and wide temperature fluctuations.

• Real-Time Performance – Handles time-sensitive tasks with precise scheduling and deterministic response.

• Maintenance Friendly – Battery-backed SRAM retains user programs during power loss, minimizing downtime.
