GE IC698ETM001-EP PACSystems RX7i Ethernet Interface Module

Description

The GE IC698ETM001-EP (a production revision of the IC698ETM001 series) resolves the critical need for high-performance, native Ethernet connectivity in PACSystems RX7i controllers, enabling seamless integration with modern plant networks, SCADA systems, HMIs, and peer devices without external gateways or protocol converters.

In industrial automation environments using RX7i (the VME-based successor to Series 90-70)—common in power generation, oil & gas, chemicals, or large discrete processes—engineers often struggle with outdated serial-only communication or add-on modules that consume rack space, add latency, or limit simultaneous connections. These issues can hinder real-time data exchange for global variables, remote diagnostics, program uploads/downloads, or Modbus TCP interfacing, leading to slower fault resolution, restricted scalability, or higher engineering overhead in process control setups requiring deterministic peer-to-peer links.

The GE IC698ETM001-EP becomes essential when your RX7i CPU (such as IC698CPE-series) requires a dedicated Ethernet interface with dual auto-sensing 10/100 Mbps ports, supporting TCP/IP services like SRTP (for client/server messaging), EGD (Ethernet Global Data for periodic peer broadcasting), Modbus TCP, and web-based diagnostics. It’s particularly valuable in retrofits of legacy VME racks, expansions needing high-throughput networking, or facilities upgrading to Ethernet for remote access and cybersecurity hardening. By providing a 200 MHz Ethernet processor, embedded web server, and robust isolation, GE IC698ETM001-EP ensures high reliability in network-linked data, offloads communication from the CPU, and supports up to eight SRTP channels plus EGD—critical for maintaining critical system uptime in applications where seamless connectivity prevents production interruptions.

The GE IC698ETM001-EP operates as a standalone Ethernet peripheral module in the PACSystems RX7i family, acting as a high-performance TCP/IP coprocessor with its own 200 MHz processor to manage network traffic independently of the main CPU. It mounts in any available RX7i rack slot (VME64 compatible), drawing power from the backplane, and features dual RJ-45 ports with auto-MDIX for straight-through or crossover cables, plus support for full/half-duplex operation.

In a typical industrial automation stack, the module connects to the plant Ethernet LAN (or dedicated control network) via Category 5+ cabling, enabling the RX7i to publish/subscribe global data via EGD, handle SRTP requests for explicit reads/writes, serve as a Modbus TCP server/client, and provide an embedded web server for diagnostics (e.g., station manager pages for IP config, statistics, and fault logs). It integrates with the CPU via the VME backplane for configuration through Emerson Automation Studio (formerly Proficy Machine Edition), supports dual static IPs or DHCP, and includes 1500 VAC port-to-backplane isolation for noise immunity. While it lacks native redundancy (use multiple modules or network-level redundancy), it excels in centralized architectures requiring fast, reliable Ethernet bridging for supervisory integration in process control environments.

Choosing the GE IC698ETM001-EP brings dependable, high-speed Ethernet to RX7i deployments. Engineered with dual ports and a dedicated 200 MHz processor, it handles heavy network traffic efficiently—supporting EGD for deterministic global data sharing and SRTP for flexible client/server operations—while minimizing CPU overhead and enabling remote access that accelerates troubleshooting and reduces site visits.

Maintenance teams gain from the embedded web server for browser-based diagnostics (IP setup, port stats, firmware checks), clear front-panel LEDs for status/link/activity/faults, and easy configuration in Automation Studio without disrupting runtime. Its robust isolation and auto-MDIX simplify cabling, while the module’s design tolerates industrial noise and temperature variations. In legacy VME plants, GE IC698ETM001-EP future-proofs connectivity cost-effectively, facilitating integration with modern tools and lowering total ownership costs through reliable process control networking.

The GE IC698ETM001-EP is commonly deployed in RX7i systems across industries transitioning to Ethernet-centric operations. In power generation and utilities, it’s used to connect RX7i controllers to SCADA, historians, or peer PLCs for turbine monitoring, substation data exchange, or grid synchronization, ensuring critical system uptime through fast diagnostics and global data. Chemical and petrochemical facilities favor it for process networking, enabling EGD between controllers for coordinated batch or continuous loops in distributed plants.

Heavy manufacturing and water treatment sites also rely on this interface for machine-to-machine links or remote monitoring, supporting reliable data flow in noisy or extended environments. Across these, the GE IC698ETM001-EP excels when native 10/100 Ethernet with SRTP/EGD directly improves visibility, reduces latency, and enhances system integration.

Here are some compatible or related products in the GE RX7i PACSystems and communication families:

• IC698ETM001 – Base or earlier revision (EP is a later production variant; fully interchangeable)
• IC698CPE010 / IC698CPE020 – RX7i CPUs that pair with this Ethernet module for embedded networking
• IC698CRE020 – Redundancy CPU often used with multiple ETM001 for high-availability Ethernet

Before installing the GE IC698ETM001-EP, confirm RX7i rack slot availability (any slot except Slot 1 CPU) and ensure backplane power meets 1.5 A max at 5 VDC. Select RJ-45 cabling (Cat5+), configure IP/subnet, EGD exchanges, and SRTP channels via Emerson Automation Studio, and pre-validate connectivity (ping, web server access at default IP) in a test rack. Check firmware compatibility (update via web or Studio if needed) and verify network topology for full-duplex operation.

Ongoing maintenance involves routine LED checks during rounds—monitor for link/activity, faults, or power issues—and annual inspection of RJ-45 ports/cables for damage or corrosion. Use the embedded web server or Studio diagnostics to review stats, clear faults, or update firmware from Emerson resources. As a dedicated coprocessor module with no moving parts, failures are infrequent, but spares support quick swaps to restore networking without downtime.
