The GE Fanuc IC695RMX128-CG is an I/O Link Interface Module designed for the Series 90-30 programmable controller platform. It provides a communication interface between a Series 90-30 PLC and a Fanuc I/O Link master, allowing control data to be exchanged between the PLC and connected I/O devices.

Product Overview

This module operates as a slave device on the proprietary Fanuc I/O Link network. It can be configured for either 32 or 64 I/O points, making it suitable for systems with different data exchange requirements. In addition, the module uses a single Series 90-30 rack slot and receives its operating power from the PLC backplane.

The interface is particularly useful where a Series 90-30 controller needs to communicate with Fanuc CNC equipment or another compatible I/O Link master. Therefore, it can help integrate PLC control with machine-level I/O without requiring a separate conventional I/O wiring architecture.

Technical Specifications

The 32-point or 64-point configuration is selectable during installation. Consequently, the module can be matched to the I/O capacity required by the particular control system.

Communication Function

The main purpose of this module is to provide the Series 90-30 PLC with an interface to the Fanuc I/O Link. The Fanuc I/O Link is a serial communication system intended for high-speed data exchange between a master device and connected slave devices.

Because the module works as a slave, the I/O Link master controls the communication relationship. Meanwhile, the Series 90-30 PLC can exchange the configured I/O data through the interface. This arrangement is useful in machine-tool and industrial automation systems where PLC and CNC-related equipment need to share I/O information.

Furthermore, the serial interface simplifies communication between the controller and compatible Fanuc equipment compared with individually wiring every signal between separate systems.

Application Areas

This interface module can be used in a variety of industrial automation environments, particularly where GE Fanuc Series 90-30 controllers are integrated with Fanuc-based equipment.

Typical applications include:

• CNC machine control
• Factory automation
• Machine-tool systems
• Fanuc CNC integration
• Production-line equipment
• PLC-to-machine I/O communication
• Industrial manufacturing systems
• Legacy Series 90-30 control installations

In these applications, the module provides a practical bridge between PLC logic and I/O Link-based equipment. Moreover, its selectable I/O capacity gives system designers additional flexibility when adapting an existing installation.

Installation and Maintenance

Before installation, confirm that the rack configuration, backplane type, I/O capacity, and Fanuc I/O Link wiring are compatible with the module. The correct configuration should also be established before the system is placed into normal operation.

During maintenance, technicians should inspect the communication connectors, wiring, and module seating. In addition, the OK and RDY indicators can be checked to identify basic operating conditions.

The operating temperature range is generally specified as 0°C to +60°C. Therefore, adequate cabinet ventilation and temperature control should be maintained when the module is installed in an industrial enclosure.

Replacement Considerations

When replacing an existing unit, verify the complete catalog number and hardware revision rather than relying only on the general product family. The E revision should be matched carefully with the existing system configuration.

Also, confirm whether the application uses a 32-point or 64-point configuration and check the existing I/O Link master arrangement before commissioning the replacement.

Overall, this module remains useful for maintaining established Series 90-30 and Fanuc I/O Link installations. Its compact rack design, slave communication architecture, and selectable I/O capacity make it a practical interface component for legacy industrial automation systems.
