Procure now IC695NIU001 GE Fanuc Ethernet NIU
The IC695NIU001 is an advanced PACSystems RX3i Ethernet Network Interface Unit (NIU) engineered by GE Fanuc. This highly sophisticated communications module is designed to allow a PACSystems RX3i rack to function as a powerful, decentralized remote I/O node. By utilizing high-speed Ethernet connectivity, the IC695NIU001 continuously exchanges critical input and output data with a central RX3i controller via the EGD (Ethernet Global Data) protocol. This architecture drastically reduces the need for long, expensive field wiring runs by placing the I/O processing hardware directly next to the mechanical process. Equipped with robust processing capabilities, this module ensures deterministic data delivery and seamless integration into large-scale, distributed control environments.

Expert Tips for Network Integration
When deploying the IC695NIU001 in an industrial setting, leveraging its dual RJ-45 ports can significantly enhance network resilience. These ports act as an unmanaged switch, allowing technicians to daisy-chain multiple NIU racks without requiring external industrial switches in every control panel. However, to prevent broadcast storms and optimize the EGD packet exchange, it is highly recommended to implement IGMP snooping on your primary managed switches. Always assign a static IP address to the NIU before deployment, ensuring that the subnet mask aligns perfectly with the master RX3i CPU to avoid loss of deterministic communication.
Firmware Management and Maintenance
The IC695NIU001 features flash-upgradable firmware, which allows the unit to adapt to evolving network security standards and enhanced GE Fanuc protocols. Routine maintenance should include verifying the operating temperature of the module, as network interfaces are susceptible to thermal degradation if the cabinet’s cooling system fails. The front-panel LED diagnostics provide an immediate visual cue regarding network health; a solid green «LAN OK» light indicates proper synchronization, while flashing red signifies a configuration mismatch or cable fault.
Related Control Components
To populate your remote Ethernet node effectively, this NIU works flawlessly when hosting high-density digital modules like the IC695MDL664 discrete input card, or precision monitoring units such as the IC695ALG600 analog module.
Frequently Asked Questions (FAQs)
Q: Does the IC695NIU001 execute local control logic?
A: No, the NIU acts strictly as a remote I/O interface. All control logic is executed by the central RX3i CPU, which then commands the outputs on the NIU’s rack.
Q: Which backplane does this module require?
A: It must be installed in an RX3i universal backplane, utilizing the high-speed PCI bus for rapid data exchange with the installed I/O modules.
