Product Overview

The IC693PCM311 is a Programmable Coprocessor Module (PCM) designed for the GE Fanuc / Emerson Series 90-30 PLC platform. This 100% brand new, original module functions as an independent processing unit within the PLC rack, offloading intensive computations and serial communication tasks from the main CPU. With 640 KB of memory and support for MegaBasic and C programming, it is ideal for data handling, complex calculations, and multi-device communication without impacting PLC scan performance.

Technical Specifications

Engineering Advantages

Independent Processing Power
Executes complex logic and data processing independently from the main PLC CPU, ensuring that core control tasks maintain consistent scan performance even under heavy computational load.

Advanced Dual Serial Communication
Two fully configurable serial ports enable simultaneous communication with multiple external devices such as barcode scanners, printers, scales, and third-party controllers using different protocols and baud rates.

High-Capacity Local Memory
640 KB of onboard memory supports extensive data buffering, recipe storage, and local logging before transferring data to SCADA or HMI systems.

Autonomous Execution Environment
The module operates its own embedded runtime system, allowing applications to run continuously without affecting real-time PLC control operations.

FAQs

What software is required to program the IC693PCM311?
It is typically programmed using Proficy Machine Edition (PME) or legacy PCM tools. Applications are developed in MegaBasic or C and downloaded via serial communication tools.

Does it require battery backup?
Yes. Program and data retention depends on the Series 90-30 system lithium battery located in the power supply module. A weak battery may result in data loss.

Can both serial ports be used at the same time?
Yes. Both ports operate independently and can be configured with different protocols and communication parameters.

Is it compatible with RX3i systems?
It is a Series 90-30 module. While it may physically fit in some RX3i configurations, modern RX3i systems typically use newer integrated processors or communication modules for equivalent functionality.
