GE IC693PCM301 Programmable Coprocessor Module for Series 90-30 PLC

Product Overview

When your Series 90-30 PLC needs to communicate with diverse serial devices, the GE IC693PCM301 Programmable Coprocessor Module provides a reliable interface. This high-performance microcomputer module acts as a coprocessor, adapting to applications that require either Communications Coprocessor Module (CCM) or ASCII/BASIC Module (ABM) functionality. It simplifies integration by occupying a single slot in any Series 90-30 baseplate, though hot-swapping is not supported.

Technical Specifications

The IC693PCM301 includes 2 serial ports for flexible connectivity. It supports both CCM and ASCII/BASIC Module operations, allowing you to configure the module for your specific communication needs. Three status LEDs—one OK LED and two user-configurable LEDs (User 1 and User 2)—provide clear visual feedback. The OK LED illuminates during normal operation, turns off when the module is not working, and flashes during power-up diagnostics. An internal lithium battery maintains user memory after power interruptions, ensuring data integrity.

Industry Applications

In manufacturing environments, the IC693PCM301 enables industrial computers, peripheral monitors, and process controllers to exchange data with a Series 90-30 PLC. For example, in a material handling system, the module can run MegaBasic applications for real-time data acquisition and storage, allowing operators to monitor conveyor status and adjust parameters without PLC programming changes. In a batch processing plant, the PCM can serve as a CCM to coordinate multiple serial instruments, reducing wiring complexity and centralizing control.

Installation & Setup Guidance

Installing the IC693PCM301 is straightforward—it fits into a single slot of any Series 90-30 baseplate. Before installation, power down the system because hot-swapping is not permitted. After seating the module, connect serial devices to the two ports according to your application (CCM or ABM mode). Configure the module using the MegaBasic interface functions, which allow you to edit data acquisition, storage, and real-time computing tasks. Always verify that the OK LED is on after power-up to confirm proper operation.

Maintenance & Reliability

The IC693PCM301 requires minimal routine maintenance. Periodically inspect the module for dust accumulation and ensure adequate ventilation around the baseplate. The internal lithium battery preserves user memory during power loss, but replace it according to the manufacturer’s schedule to prevent data loss. Monitor the OK LED during operation; if it turns off or flashes unexpectedly, check the module seating and power supply. Because the module does not support hot-swapping, always power down before removal or replacement.

Compatibility & Integration

The IC693PCM301 is designed exclusively for the GE Fanuc Series 90-30 PLC platform. It integrates seamlessly with the baseplate and communicates with a wide variety of serial devices through its two ports. The module supports both CCM and ASCII/BASIC modes, making it compatible with industrial computers, peripheral monitors, and process controllers that use serial protocols. MegaBasic interface functions enable custom data handling, so you can tailor the module to your specific application without additional hardware.

Selection Guide & Purchasing Advice

Before purchasing the IC693PCM301, verify that your Series 90-30 baseplate has an available single slot. Confirm that your application requires either CCM or ABM operation, as the module can be configured for either mode. Ensure your serial devices use compatible ports and protocols.
