The GE Fanuc IC695ETM001CA-ER is a dedicated Ethernet communications coprocessor for the PACSystems RX3i controller platform. This “CA-ER” version is a specific revision of the standard ETM001, typically reflecting hardware enhancements for improved thermal stability and long-term reliability in high-traffic industrial networks. It provides high-speed, redundant Ethernet connectivity, allowing the RX3i CPU to interface with HMIs, SCADA systems, and other controllers without consuming the CPU’s primary processing cycles.

Application Fields
The IC695ETM001CA-ER is a critical component in distributed control systems (DCS) and large-scale PLC networks. It is widely used in automotive manufacturing, power plant automation, and water treatment facilities. Its primary role is to handle heavy data traffic—such as high-speed peer-to-peer data exchange via EGD or remote programming via SRTP—ensuring that the main CPU remains dedicated to logic execution and time-critical safety tasks.
Product Instructions
The module should be installed in any universal slot of a PACSystems RX3i Universal Backplane (IC695 series). Configuration is performed using GE Proficy Machine Edition software. Within the hardware configuration, you must assign a unique IP address and define the protocols being used. For high-availability systems, multiple ETM001 modules can be installed in a single rack to provide redundant communication paths. Always verify the module’s “OK” and “LAN” LED status after installation; a solid green “LAN” LED indicates an active link, while a flashing “DATA” LED confirms active traffic.
FAQ: Common Questions and Answers
Q: What is the difference between the ETM001 and the built-in Ethernet on some RX3i CPUs? A: While many RX3i CPUs have integrated Ethernet, the IC695ETM001 serves as a dedicated coprocessor. This means it has its own processor to handle network stacks and protocols, preventing network “storms” or heavy HMI traffic from slowing down the PLC’s logic scan time.
Q: Can I use this module for Modbus TCP communication? A: Yes, the IC695ETM001 fully supports Modbus TCP as both a client (initiating requests) and a server (responding to requests), making it highly compatible with third-party devices like VFDs and power meters.
Q: Does the “CA-ER” suffix mean it is specialized for certain regions? A: Generally, these suffixes refer to internal hardware revisions or environmental ratings (such as Conformal Coating or Extended Reliability). The “CA” often denotes conformal coating, which protects the circuitry from moisture and corrosive contaminants.
