EMERSON IC695ETM001-LDAB Replacement for PACSystems RX3i

Product Overview

EMERSON IC695ETM001-LDAB Replacement for PACSystems RX3i: Seamless Migration & Upgrade Solution

The EMERSON IC695ETM001-LDAB is a high-performance Ethernet TCP/IP Interface Module designed for the GE Fanuc / EMERSON PACSystems RX3i control platform. As legacy automation systems age and original modules reach end-of-life, facilities engineers and procurement teams face mounting pressure to source verified replacement units that maintain full backward compatibility with existing rack infrastructure, wiring terminations, and PROFINET or Ethernet/IP communication architectures.

At TOPNLMS, we specialize in sourcing, testing, and supplying hard-to-find industrial control components including the IC695ETM001-LDAB. Whether you are executing a like-for-like swap on a production line, upgrading a legacy Series 90-30 or Series 90-70 system to the PACSystems RX3i platform, or building a spare-parts inventory for critical infrastructure, this module ships ready for installation with full documentation support.

The IC695ETM001-LDAB occupies a single slot in the IC695CHS012 or IC695CHS016 universal backplane and communicates over standard 10/100 Mbps Ethernet using TCP/IP, SRTP (Service Request Transfer Protocol), and Modbus TCP protocols. Its dual RJ-45 ports support both a dedicated station manager port and a LAN port, enabling seamless integration into existing plant network topologies without requiring additional switches or media converters. Engineers migrating from older IC693CMM321 or IC693CMM311 serial communication modules will find the transition to Ethernet-based communication straightforward, with PAC Machine Edition (PME) software providing a unified programming environment across both legacy and current hardware generations.

Seamless Upgrade Solutions

A successful migration to the IC695ETM001-LDAB rarely involves a single module swap. In practice, field engineers upgrading from a Series 90-30 or early RX3i configuration will typically need to evaluate the entire control cabinet assembly. The IC695PSA040 power supply module is the standard companion unit for RX3i racks, providing the regulated 5 VDC and 3.3 VDC backplane power required by the ETM001-LDAB and co-resident I/O modules. If the existing cabinet uses an older IC693PWR321 or IC693PWR330 power supply, a power budget review is essential before commissioning.

On the I/O side, facilities transitioning from Series 90-30 discrete I/O will find that IC694MDL340 (16-point 24 VDC input) and IC694MDL754 (16-point relay output) modules mount directly into the IC695CHS012 universal backplane alongside the ETM001-LDAB, preserving existing field wiring terminations on the IC694ACC300 terminal block assemblies. This wiring compatibility is a critical cost-saving factor: field cables, conduit runs, and junction boxes remain untouched, and only the backplane-side module is replaced.

For applications requiring analog signal conditioning, the IC695ALG600 universal analog input module supports thermocouple, RTD, voltage, and current inputs in a single slot, replacing multiple legacy IC693ALG220 or IC693ALG221 analog modules. Signal isolation requirements common in process industries can be addressed by adding DIN-rail-mounted signal isolators within the same control cabinet, maintaining CE and UL compliance without structural cabinet modifications.

Communication architecture upgrades often extend beyond the ETM001-LDAB itself. Sites running legacy GENIUS bus I/O will need a IC695GCG001 GENIUS Communications Gateway to bridge existing GENIUS drop nodes to the RX3i Ethernet backbone. Similarly, installations with remote I/O drops connected via Profibus DP can integrate a IC695PBM300 Profibus Master module in the same RX3i rack, consolidating multiple legacy communication masters into a single unified chassis. For HMI connectivity, the ETM001-LDAB’s Modbus TCP support enables direct integration with WEINTEK MT8071iE or equivalent Ethernet-capable HMI panels without requiring additional protocol converters, simplifying the SCADA layer of the upgraded system.

Programming cable requirements also change during migration. The IC690USB901 USB-to-serial programming cable is no longer needed once the RX3i CPU (such as the IC695CPE305 or IC695CPE400) is configured for Ethernet-based programming via PME. Engineers can program, monitor, and update logic over the plant LAN using the same IC695ETM001-LDAB Ethernet port, eliminating the need for dedicated serial programming drops at each panel.

Retrofit Guidance FAQ

Q: Is the IC695ETM001-LDAB a direct replacement for the IC695ETM001-CA or IC695ETM001-AAAB?
A: Yes. The -LDAB firmware revision is backward compatible with earlier IC695ETM001 hardware revisions. Configuration files created in PAC Machine Edition for earlier revisions load without modification. Verify the PME hardware configuration target matches the installed CPU firmware version.

Q: Can I retain my existing field wiring when replacing a Series 90-30 communication module?
A: Field wiring to I/O terminal blocks is unaffected by the ETM001-LDAB installation. However, the transition from serial to Ethernet communication requires new Cat5e or Cat6 patch cables from the module’s RJ-45 LAN port to the plant switch. No changes to field cable runs, conduit, or junction boxes are required.

Q: What programming changes are needed after installing the IC695ETM001-LDAB?
A: In PAC Machine Edition, add the ETM001 to the hardware configuration under the RX3i rack, assign an IP address, and configure SRTP or Modbus TCP channels as required. Existing ladder logic and function block programs do not require modification. COMMREQ function blocks used for serial communication in legacy programs must be updated to use Ethernet channel commands.

Q: Does the module fit in the existing control cabinet without physical modifications?
A: The IC695ETM001-LDAB occupies one universal slot in the IC695CHS012 or IC695CHS016 backplane. If the existing cabinet already houses an RX3i rack, no physical modifications are required. Migrations from Series 90-30 cabinets require backplane replacement (IC695CHS012) and a power supply evaluation (IC695PSA040), but the overall rack footprint is similar, and most standard 19-inch or 24-inch control cabinet enclosures accommodate the RX3i chassis without structural changes.

Q: Is the module compatible with Modbus TCP SCADA systems?
A: Yes. The IC695ETM001-LDAB supports Modbus TCP server functionality natively. SCADA systems using Modbus TCP polling (Wonderware, iFIX, Ignition, etc.) can communicate directly with the RX3i CPU’s data tables via the ETM001-LDAB without additional gateways or protocol converters.

Q: What is the lead time and shipping arrangement?
A: In-stock units ship from Xiamen, China within 1–3 business days of order confirmation. International express delivery (DHL, FedEx, UPS) typically reaches most destinations within 3–7 business days. Expedited shipping options are available for emergency breakdown situations. All units are inspected and function-tested prior to dispatch.
