Description
Product Introduction
The IC695ETM001 is an Ethernet Interface module in the PACSystems RX3i family from GE Fanuc, now Emerson. It connects RX3i CPUs to Ethernet networks for data exchange, programming, and SCADA communications. This module sits in the main rack and handles TCP/IP traffic alongside the main CPU.
Field experience shows the built-in 200 MHz processor and embedded Ethernet switch set it apart from basic comm modules. You get two auto-sensing 10/100 ports plus daisy-chain capability without extra hardware. It takes some load off the main CPU for network tasks, which matters in larger systems.

Application Scenarios & The “Trench” Experience
Picture this. A bottling plant in Texas lost network comms to their HMI at shift change. The old Ethernet module overheated and dropped offline. Production halted while they troubleshot. We overnighted an IC695ETM001, swapped it in 20 minutes, and they made quota. Downtime like that hurts the soul.
- Water Treatment – SCADA network backbone – The dual ports and switch let you connect multiple devices without adding switches in tight panels.
- Manufacturing – Machine-to-machine data exchange – Handles Modbus TCP traffic reliably while the main CPU runs logic.
- Oil & Gas – Remote terminal unit integration – Embedded switch simplifies daisy-chaining RTUs on the same Ethernet segment.
- Pharmaceutical – Validation data logging – Stable Ethernet connection ensures no dropped packets during batch records transfer.
One refinery used these modules during a control system migration. The ETM001 bridged old and new networks cleanly. Saved hours of rewiring and kept the DCS talking without a hitch.

Transparency SOP: Quality Assurance & Testing
We don’t just ship boxes; we test them on actual RX3i racks.
- Inbound Inspection – Anti-counterfeit check, OEM seal verification, physical damage inspection.
- Live Rig Testing – Power-up, Ethernet link negotiation, ping tests, SRTP communication handshakes.
- Electrical Parameter Checks – Verify port isolation and current draw.
- Firmware Verification – Confirm firmware revision and station manager port functionality.
- Final QC & Anti-static Packaging – Full functional test, label verification, ESD-safe shipping.
Every module gets real-world network testing before release.
The Veteran’s Tech Trap Guide
⚠️ Don’t forget the station manager cable. Many guys grab the module and forget the RS-232 cable for initial setup. Without it, troubleshooting IP settings gets painful.
❗ IP address conflicts kill networks fast. Document your subnet before install. The module only supports one IP address — plan your addressing scheme or you’ll chase ghosts for hours.
⚠️ Watch the embedded switch limitations. It works great for daisy chaining a few nodes. Load it up with too many devices and latency creeps in. Test your topology.
One thing to watch out for is firmware mismatch with the CPU. Older ETM001 revisions may need updates to talk properly with newer RX3i firmware. Always verify compatibility first.
Frequently Asked Questions
Does the IC695ETM001 support hot-swapping? No. Power down the rack before inserting or removing. Live insertion risks backplane faults.
How many Ethernet ports does it really give me? Two 10/100 Mbps ports with auto-negotiation plus the embedded switch for daisy chaining.
Can I use it for Modbus TCP? Yes. It handles Modbus TCP server and client roles alongside SRTP and other protocols.
Why buy surplus instead of new from Emerson? These come from reliable excess stock. We test every one thoroughly. You get the same performance at a lower price with our 12-month warranty.
What cable do I need for the station manager port? Standard RS-232 null modem or straight cable depending on your laptop setup. Check the manual for pinouts.
Is this module still supported? Yes, though newer RX3i Ethernet options exist. The ETM001 remains a solid choice for many legacy and new installations.
Will it work in an RX3i rack with mixed generation modules? Generally yes. Confirm backplane compatibility and power budget for your specific configuration.
