GE Fanuc URGHH UR Series Ethernet Communication Module

Overview

Configured for deterministic Ethernet packet exchange in UR Series protection and control networks, the GE Fanuc URGHH (URGHH Ethernet Communication Module) provides direct physical/electrical execution for high-speed I/O and diagnostics data transport across UR Series backplane-integrated communication architecture.

Hardware Specifications

GE UR Series Deterministic Communication Characteristics

The URGHH module integrates into GE UR Series backplane communication structure with deterministic Ethernet scheduling behavior. Network traffic handling is aligned with industrial control execution requirements, supporting synchronized data exchange between protection relays and supervisory nodes.

Within GE industrial control architectures, backplane bus communication velocity is coordinated with firmware-level I/O scheduling and EtherNet/IP-style deterministic network behavior. Firmware flash compatibility across UR Series nodes allows controlled update cycles without disrupting active communication sessions. I/O data density scaling is handled through modular UR rack expansion logic, maintaining consistent latency boundaries under mixed diagnostic and control traffic loads.

Suffix Breakdown & Model Matrix

No formal suffix segmentation is defined for URGHH. The model identifier is treated as a single fixed hardware designation without documented modular postfix structure or functional subcode decomposition.

Frequently Asked Questions

Q: Does URGHH support hot-swap replacement in UR Series racks?
A: Hot-swap capability depends on UR chassis configuration. The module supports controlled removal procedures when backplane communication is quiesced.

Q: What is the Ethernet redundancy behavior of the dual ports?
A: Dual 100 Mbps ports operate in full-duplex mode and support redundant communication paths depending on system-level configuration.

Q: Can firmware updates be applied while the module is online?
A: Firmware flashing is typically executed through controlled maintenance windows to preserve deterministic communication states.

Field Installation Guidelines

Install the module into the designated UR Series backplane slot with verified connector alignment. Ensure chassis power (28 VDC nominal) is isolated prior to insertion.

Maintain proper shield termination for Ethernet cabling at both enclosure entry and switch termination points. Avoid excessive cable bending radius below manufacturer industrial Ethernet minimum standards.

Verify grounding continuity of rack enclosure before commissioning. Do not introduce mixed potential grounding between communication shield and protective earth reference.
