GE Fanuc IC693PCM311

Product Overview: GE Fanuc IC693PCM311

The GE Fanuc IC693PCM311 is a Programmable Coprocessor Module specifically designed for the Series 90-30 Programmable Logic Controller (PLC) system. This module plays a critical role in extending the computing capability of the host PLC by allowing users to offload specialized or processor-intensive tasks, such as serial communication handling and custom control logic, from the main CPU.

It serves as an embedded computing platform within the PLC system, enabling users to write and execute custom applications using languages like MegaBasic and C. The IC693PCM311 is ideal for engineers seeking enhanced flexibility, real-time performance, and additional communication ports without upgrading to a more powerful PLC CPU.

Key Features

1. Dedicated Processing Power

• The IC693PCM311 functions as a standalone computing module with its own processor, independent from the main CPU.

• This allows it to handle computationally demanding tasks or non-deterministic processes without affecting the main control logic of the PLC.

2. Ample Memory Resources

• The module provides 640 KB of battery-backed RAM, allowing for non-volatile program and data storage.

• An additional 192 KB is reserved for MegaBasic applications.

• Memory is backed by a replaceable lithium battery to ensure data retention during power failures.

3. Communication Interfaces

• Two serial ports are available: one for RS-232 and one configurable for RS-232 or RS-485.

• These ports are used for communicating with external devices such as drives, barcode scanners, operator interfaces, and other controllers.

4. Protocol Support

• Supports both Modbus RTU (Master/Slave) and GE’s proprietary CCM protocols.

• Enables integration with third-party equipment and legacy systems.

5. Flexible Programming

• Applications can be developed in MegaBasic or C.

• This allows for implementation of complex logic and real-time data manipulation beyond the native capabilities of the PLC ladder logic.

6. Status Monitoring

• Equipped with three LED indicators: one for the module’s operational status and two for serial communication ports.

• Useful for diagnostics and operational visibility.

7. User-Controlled Operation

• Provides the ability to restart the coprocessor module independently using an onboard push-button.

• This is essential during debugging and updates without impacting the entire PLC system.

8. Environmental Durability

• Designed to operate in industrial environments, with standard Series 90-30 enclosure ratings for resistance to temperature fluctuations, vibration, and dust.

Applications

The IC693PCM311 module is widely used in industrial environments where real-time processing and external communication are essential. Typical application areas include:

• Automated Material Handling: Real-time control and feedback for conveyor systems, sorters, and AGVs.

• Packaging Systems: Data-intensive control for high-speed packaging lines that require synchronized operations with sensors and actuators.

• Textile Machinery: Custom motion control logic for looms, spindles, and fabric cutting machinery.

• Food and Beverage Processing: Ensures repeatable and precise control in batch processing, filling lines, and CIP (Clean-In-Place) systems.

• Water and Wastewater Treatment: Communicates with analyzers and flow meters; handles customized logging and reporting of treatment data.

• OEM Embedded Control: Used by machine builders to integrate tailored software logic directly within the machine controller.

• Remote Terminal Units (RTUs): Acts as a field processor in SCADA systems for remote telemetry and device interfacing.

• Data Acquisition Systems: Collects, preprocesses, and transmits sensor data to host systems or SCADA applications.

Why Choose GE Fanuc IC693PCM311

1. Extends PLC Capability Without System Overhaul

Many legacy systems using Series 90-30 PLCs are still operational today. The IC693PCM311 offers a way to expand system functionality—especially communication and custom logic—without replacing the entire control system.

2. Reduces Main CPU Load

By isolating communication and application-specific processing to the coprocessor, the main CPU is free to handle its core real-time control tasks more reliably.

3. Improves System Flexibility

The programmable nature of the module allows engineers to develop custom applications that respond to specific process or system requirements, such as protocol conversions, data filtering, or complex decision trees.

4. Reliable and Industrial-Proven

The IC693PCM311 has been deployed in thousands of industrial applications over decades. It has a strong track record for reliability and is supported by a large installed base and ecosystem of tools and documentation.

5. Cost-Effective Expansion

Compared to upgrading to a higher-end CPU or changing entire platforms, adding a PCM311 module is a low-cost method of adding powerful new features to existing systems.

6. Integration with Legacy and Modern Devices

The dual serial ports and protocol support make it a great solution for bridging communication between older serial devices and modern control systems or HMIs.
