IC695ETM001 Product Description

The GE IC695ETM001 is a high-performance Ethernet Communication Module engineered for the PACSystems RX3i control platform. Designed to deliver deterministic, high-speed network connectivity within distributed automation architectures, the IC695ETM001 serves as the primary Ethernet backbone interface between the RX3i CPU backplane and plant-level SCADA, historian, HMI, and peer controller networks. Its role in the control hierarchy spans the communication layer, bridging real-time process data from the I/O layer upward to supervisory and enterprise systems with minimal latency and maximum protocol flexibility. Whether deployed in a simplex or redundant control architecture, the IC695ETM001 provides the network stability and contextual integration required for mission-critical industrial environments.

The IC695ETM001 achieves its full value when deployed as part of a cohesive PACSystems RX3i automation platform. At the control layer, the IC695CPE305 or IC695CPE400 CPU modules execute the application logic and communicate with the IC695ETM001 over the high-speed RX3i backplane bus, enabling real-time data exchange without introducing scan-cycle latency. The IC695PSD040 power supply module provides stable backplane power to all installed modules, including the ETM001, ensuring consistent electrical performance across the rack.

On the I/O layer, analog input modules such as the IC695ALG600 and digital I/O modules like the IC694MDL754 feed process data into the CPU, which the IC695ETM001 then makes available to upstream SCADA and historian systems via SRTP or Modbus TCP. For applications requiring distributed I/O expansion, the IC695CMM002 serial communications module or IC695PBM300 PROFIBUS master module can extend the control architecture into field device networks, with the IC695ETM001 maintaining the supervisory Ethernet backbone.

In redundancy-critical applications — such as power generation, water treatment, or continuous process control — the IC695ETM001 pairs with the IC695RMX128 redundancy memory exchange module to support hot-standby CPU redundancy configurations. This ensures that Ethernet communication continuity is maintained during CPU switchover events, preserving SCADA connectivity and historian data integrity without operator intervention.

At the HMI layer, operator interface terminals running GE's Proficy HMI/SCADA iFIX or third-party SCADA platforms connect directly to the IC695ETM001 via standard Ethernet, leveraging the SRTP driver for high-speed tag polling. Industrial Ethernet switches — such as unmanaged DIN-rail switches rated for 0–60°C operation — are recommended between the IC695ETM001 and the HMI network to provide port isolation and network segmentation. For time-sensitive applications, the IC695ETM001 supports Ethernet Global Data (EGD) for peer-to-peer data exchange between multiple RX3i controllers, enabling coordinated multi-axis or multi-zone control without routing through a central SCADA server.

Manufacturing & Discrete Assembly: In automotive body-in-white lines and electronics assembly facilities, the IC695ETM001 connects PACSystems RX3i controllers to MES and ERP systems, enabling real-time production count reporting, recipe management, and alarm forwarding. Its deterministic SRTP communication ensures that production data reaches the historian within the scan cycle, supporting OEE calculation and downtime analysis.

Power Generation & Utilities: In gas turbine control panels and substation automation systems, the IC695ETM001 provides the Ethernet interface between the RX3i control rack and the plant DCS or energy management system. Its support for Modbus TCP allows seamless integration with legacy SCADA systems without protocol conversion hardware, reducing engineering cost and potential failure points.

Water & Wastewater Treatment: Municipal water treatment facilities deploy the IC695ETM001 in redundant RX3i architectures to maintain continuous SCADA visibility over pump stations, chemical dosing systems, and filtration processes. The module's DHCP/BOOTP support simplifies IP address management across geographically distributed pump stations connected via fiber Ethernet infrastructure.

Oil, Gas & Petrochemical: In pipeline SCADA and compressor station control applications, the IC695ETM001 enables high-speed data acquisition from RX3i-controlled field panels to central control rooms. Its operating temperature range and backplane-powered design reduce the number of field-installed power supplies, simplifying panel design in hazardous area enclosures.

Mining & Metals: Conveyor control systems and ore processing plants use the IC695ETM001 to integrate RX3i controllers with plant historians and condition monitoring systems. The module's FTP server capability allows automated upload of diagnostic logs and configuration backups, supporting predictive maintenance programs without requiring on-site engineering access.

Q1: Can the IC695ETM001 support simultaneous SRTP and Modbus TCP connections in the same RX3i rack? Yes. The IC695ETM001 supports concurrent SRTP and Modbus TCP sessions, allowing a PACSystems RX3i controller to communicate simultaneously with a GE Proficy SCADA system via SRTP and with third-party HMI or energy management systems via Modbus TCP. The number of concurrent connections is subject to the module's session limits as defined in GE publication GFK-2224; consult the datasheet for your firmware revision to confirm maximum simultaneous session counts.

Q2: Is the IC695ETM001 compatible with both IC695CHS012 and IC695CHS016 backplanes, and can it be installed in any slot? The IC695ETM001 is compatible with all RX3i universal backplanes, including the IC695CHS012 (12-slot) and IC695CHS016 (16-slot). It can be installed in any universal slot — it does not require a dedicated communications slot. However, GE recommends placing communication modules adjacent to the CPU module to minimize backplane bus loading and simplify cable routing within the control cabinet.

Q3: What does the 12-Month Warranty cover, and what is the supply and testing process for IC695ETM001 units? Every IC695ETM001 supplied by NANKMOS is covered by a 12-Month Warranty against manufacturing defects and functional failures under normal operating conditions. Prior to shipment, each unit undergoes functional verification testing including backplane communication checks, Ethernet port link negotiation, and firmware version confirmation. Units are sourced from controlled inventory channels and stored in ESD-safe environments. In-stock units are available for same-week dispatch, supporting urgent project timelines and emergency replacement requirements.
