EMERSON IC695ETM001-LDAB Retrofit Ethernet for RX3i Systems

EMERSON IC695ETM001-LDAB Retrofit-Ready Ethernet Module for RX3i Control Systems

The EMERSON IC695ETM001-LDAB is a high-performance Ethernet TCP/IP communication module engineered for the GE PACSystems RX3i platform. As legacy GE Fanuc control systems reach end-of-life or require communication infrastructure upgrades, the IC695ETM001-LDAB serves as a direct retrofit solution — enabling plants to modernize their network architecture without replacing the entire control cabinet or reprogramming core PLC logic. Whether you are migrating from an older IC695ETM001 revision, expanding Ethernet capacity in an existing RX3i rack, or recovering from a failed communication module, this unit delivers the compatibility and reliability that maintenance and procurement engineers demand.

Sourced from verified industrial supply channels and pre-tested prior to shipment, each IC695ETM001-LDAB unit is backed by a 12-month warranty and is ready for immediate deployment in production environments.

Retrofit Planning for Existing Automation Systems

A successful IC695ETM001-LDAB retrofit requires a structured review of the surrounding control architecture. Maintenance engineers should begin by auditing the RX3i rack configuration: confirm the backplane model (IC695CHS007 for 7-slot or IC695CHS012 for 12-slot), verify available slot positions, and check the power supply module — typically an IC695PSA040 or IC695PSD040 — to ensure sufficient current headroom after adding or replacing the Ethernet module.

On the CPU side, the active controller — whether an IC695CPE302, IC695CPE305, or the newer IC695CPE330 — must be running a firmware version that supports the LDAB hardware revision. If the existing firmware predates the LDAB release, a firmware update via Proficy Machine Edition is required before the module will initialize correctly. Engineers should back up the full hardware configuration and program logic from the CPU prior to any slot changes.

Network-side preparation is equally critical. The IC695ETM001-LDAB supports SRTP, Modbus TCP, and Ethernet Global Data (EGD) protocols. If the plant network uses EGD for peer-to-peer data exchange with other RX3i stations or remote I/O adapters such as the IC695RMX128 or IC695NIU001, the EGD configuration tables must be re-validated after module replacement to confirm that producer/consumer relationships remain intact. SRTP connections to SCADA systems or HMI panels — including CIMPLICITY or iFIX workstations — should be tested with a live ping and data poll before returning the system to production.

For cabinets that include IC694MDL655 or IC694MDL754 discrete I/O modules on legacy Series 90-30 expansion racks connected via the IC695LRE001 expansion adapter, engineers should verify that the Ethernet module replacement does not affect the rack communication timing. Terminal block wiring on IC694TBB032 or IC694TBB064 assemblies should be inspected for loose connections during the same maintenance window. Replacing the Ethernet module is an ideal opportunity to also inspect the IC695CMM002 serial communication module and any IC695PBM300 PROFIBUS master modules sharing the same rack, as these components are subject to the same environmental stresses and aging cycles.

If the retrofit involves migrating from a GE Series 90-70 or Series 90-30 platform to the RX3i architecture, the IC695ETM001-LDAB will serve as the primary network gateway for the new control tier. In this scenario, the programming cable (IC690USB901 or IC693CBL316) and a licensed copy of Proficy Machine Edition are essential tools for re-commissioning the CPU and downloading the converted program logic.

Downtime Control During System Migration

Minimizing unplanned downtime during an Ethernet module retrofit requires a disciplined pre-outage preparation process. Before the scheduled maintenance window, engineers should document the existing IC695ETM001 IP address, subnet mask, gateway, and all configured SRTP and EGD channel parameters. These settings must be replicated exactly on the IC695ETM001-LDAB to avoid communication faults upon restart.

The physical swap is straightforward: power down the RX3i rack via the IC695PSA040 power supply, remove the existing module from its backplane slot, seat the IC695ETM001-LDAB firmly until the backplane connector is fully engaged, and restore power. The RX3i CPU will perform a hardware scan on startup; if the module firmware and hardware revision are recognized, the CPU will transition to RUN mode without requiring a program download. If a configuration mismatch is detected, Proficy Machine Edition should be used to push the updated hardware configuration to the CPU.

Post-replacement verification should include: confirming the module’s LINK and OK LEDs are solid green, pinging the module IP from the engineering workstation, verifying SCADA or HMI data refresh on all Ethernet-connected displays, and confirming EGD data exchange with any peer controllers. A full I/O force test on critical output channels — particularly those driving motor starters, solenoid valves, or safety interlocks — should be completed before releasing the line to production. Total replacement time for a prepared team is typically under 30 minutes, making the IC695ETM001-LDAB one of the most efficient upgrade paths available for aging RX3i communication infrastructure.

Retrofit Support FAQ

Q1: Is the IC695ETM001-LDAB a direct drop-in replacement for earlier IC695ETM001 revisions?
Yes. The IC695ETM001-LDAB is backward-compatible with all earlier IC695ETM001 hardware revisions and occupies the same backplane slot. No rack modification or wiring change is required. The IP address and protocol configuration from the original module should be re-entered via Proficy Machine Edition or the module’s built-in web server after installation.

Q2: What CPU firmware version is required to support the LDAB revision?
GE PACSystems RX3i CPUs running firmware 7.0 or later (applicable to IC695CPE302, IC695CPE305, and IC695CPE330) fully support the IC695ETM001-LDAB. If your CPU firmware is older, a firmware update is recommended before installation. Contact our technical team for firmware compatibility guidance specific to your CPU serial number.

Q3: How is the module tested before shipment?
Every IC695ETM001-LDAB unit undergoes functional verification including power-on self-test, Ethernet link establishment, and protocol response testing before dispatch. Units are shipped in anti-static packaging with inspection documentation. A 12-month warranty covers all hardware defects identified after installation under normal operating conditions.

Q4: Can you supply IC695ETM001-LDAB units for long-term MRO inventory programs?
Yes. We maintain stock of IC695ETM001-LDAB modules and can support blanket orders, scheduled releases, and emergency same-day dispatch for critical plant shutdowns. Long-term supply agreements are available for procurement teams managing multi-site RX3i installations. Contact us at sales@smartnexmsk.com to discuss volume pricing and lead times.
