GE Fanuc IC695ETM001-HW

Connecting RX3i Systems to Industrial Ethernet

The GE Fanuc IC695ETM001-HW is a dedicated Ethernet communication module used with PACSystems RX3i controllers. Its primary purpose is to provide reliable Ethernet connectivity for control-system data exchange. The module uses two RJ45 network ports and supports 10/100 Mbps Ethernet communication.

Because it is designed specifically for the RX3i architecture, the module can become an important part of a plant-wide automation network where controllers, supervisory computers, and other industrial devices need to exchange information.

Key Advantages

The IC695ETM001-HW offers a practical combination of network connectivity and protocol support.

• Two Ethernet ports with RJ45 connections
• 10/100 Mbps Ethernet operation
• Auto-negotiation support
• Ethernet Global Data communication
• Modbus TCP capability
• SRTP communication
• RS-232 Station Manager interface
• One-slot RX3i module design
• Diagnostic LED indicators
• Compatibility with selected GE controller families

The published specifications identify the module as an Ethernet Interface Module rather than a conventional I/O device. Therefore, its role is focused on network communication and controller data exchange.

Network and Protocol Support

A major benefit of the ETM001 platform is its support for several industrial Ethernet communication methods. Modbus TCP, for example, can be used for communication with compatible third-party devices, while SRTP and EGD support communication within GE control architectures.

The module supports 10/100 Mbps operation with auto-negotiation. It should not be considered a Gigabit Ethernet interface.

Furthermore, its dual-port arrangement can simplify network wiring and reduce the need for additional external switching hardware in suitable system configurations.

Integration with PACSystems RX3i

The ETM001 must be installed in the main CPU rack of an RX3i system. GE documentation lists compatible Universal Backplanes such as the IC695CHS007, IC695CHS012, and IC695CHS016. The module also supports hot insertion and removal when the system configuration and applicable installation procedures permit it.

The module uses one slot and communicates with the RX3i controller through the backplane. Once installed and configured, it provides the Ethernet connection required for network-based control and monitoring functions.

Diagnostic and Service Features

Maintenance personnel can use the module's status LEDs to monitor Ethernet and diagnostic conditions. The documentation describes different LED patterns for conditions such as normal operation, diagnostics, and waiting for Ethernet configuration.

When commissioning a replacement unit, technicians should therefore check both the physical network connection and the module's LED indications. A valid IP address is required before Ethernet communication can operate normally.

Where It Fits Best

The GE Fanuc IC695ETM001-HW is well suited to:

Industrial PLC Networks: It provides Ethernet connectivity between RX3i controllers and other networked automation equipment.

Data Collection Systems: Supervisory computers can exchange control and production data through supported Ethernet services.

Legacy System Integration: The module supports communication with selected Series 90 and VersaMax controllers, making it useful in mixed-generation installations.

System Replacement Projects: Its dedicated communication function makes it a practical replacement component when an existing ETM001 installation requires maintenance.

Installation Notes

Before replacing an existing module, compare the exact IC695ETM001-HW hardware designation, rack type, controller configuration, firmware requirements, and network settings. The hardware itself cannot simply be assumed interchangeable with every ETM001 revision. GE documentation also indicates that firmware can be upgraded in the field, while the hardware cannot be upgraded in the same manner.

For long-term operation, keep network connectors clean and secure, protect Ethernet cabling from excessive mechanical stress, and periodically review communication diagnostics. Our company can provide the GE Fanuc IC695ETM001-HW for RX3i maintenance, replacement, and industrial automation projects.
