Product Introduction
When a packaging line’s SCADA system loses all communication with 12 RX3i PLCs mid-run, the root cause almost always traces back to an Ethernet module that cannot handle the full 128 concurrent SRTP connection load.
Purpose-built for the GE PACSystems RX3i platform, this single-slot EIM module integrates a native 2-port Ethernet switch, enabling linear daisy-chain topologies without extra external industrial switches. It natively supports SRTP, Modbus TCP Server/Client, and GE EGD (Ethernet Global Data) for multi-controller data sharing. It is fully configured via Proficy Machine Edition (PME) software, no extra programming tools required.

Field Application & Technical Pitfalls
This part runs three non-negotiable production-critical roles.
First, it acts as the primary Ethernet communication gateway for automotive assembly line RX3i PLCs, delivering stable 10ms-level cyclic data exchange with the central SCADA system.
Second, it enables multi-controller EGD data sharing across large material handling conveyor fleets, letting every PLC access real-time production count and status data from adjacent stations.
Third, it serves as the Modbus TCP interface for water treatment plant pump control systems, connecting the RX3i PLC to third-party flow meters and remote RTUs without protocol converters.
⚠️ Backplane Compatibility Gap Risk: This module only works with IC695 series RX3i universal backplanes. It will not fit or communicate on older Series 90-30 backplanes, and forcing it into the wrong slot will damage the backplane pins permanently.
⚠️ Firmware Version Mismatch: Hot-swap functionality only activates when the module firmware is v2.51 or newer. If you install an older v2.xx firmware unit, pulling the module live will crash the entire RX3i CPU.
⚠️ IP Address Duplication: The module’s IP address is stored in the hardware configuration. If two IC695ETM001-EK modules on the same Ethernet segment share the same IP, you will trigger a full network collision that locks all PLC communication instantly.
I watched a junior automation tech skip the firmware version check last quarter. He installed an older v2.30 firmware IC695ETM001-EK into a packaging line RX3i rack, and tried to hot-swap it later during a running shift. The CPU crashed immediately, and the entire line stayed offline for 2 hours while the team reloaded the full PLC project. That 1-minute oversight forced the operations team to scrap 80 meters of in-process packaging film.
Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against GE Fanuc’s official RX3i part revision database, run anti-counterfeit validation on the module’s laser-etched serial label, and confirm no prior rework traces on the Ethernet PHY solder joints.
- Live Rig Testing: Mount the module in a certified RX3i CPU test rack, connect it to a Proficy Machine Edition workstation, and verify 4 hours of stable SRTP and Modbus TCP communication.
- Parameter Testing: Confirm full 128 concurrent SRTP connection stability, verify 5ms minimum RPI cyclic data exchange works correctly, and log all network communication latency data.
- Final QA & Packaging: Seal the fully tested module in a static-shielding anti-static bag, apply a unique QC passed serial label, and pack it in ESD-dissipative foam with a printed hard copy of the full communication stability test report.
Frequently Asked Questions
- Can I hot-swap this module while the RX3i rack is powered on? Yes, but only if the module firmware is v2.51 or newer. You must confirm the firmware revision before performing any live swap, otherwise the CPU will fault.
- What exact GE PLC systems does this part work with? It is fully compatible with PACSystems RX3i series PLCs. It will not establish stable communication on older Series 90-30 or RX7i PACSystem platforms.
- How long is the standard warranty for this new surplus unit? It carries a full 12-month functional warranty. If it fails within that window under specified operating conditions, we cover all return shipping and bench replacement costs.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine units have the GE Fanuc hologram sticker on the side of the PCB, and the Ethernet PHY chip has the official GE part number laser-etched on the top. Refurbished clones usually skip the official hologram and use generic unmarked PHY chips that cannot support 128 concurrent SRTP connections.
- Will this IC695ETM001-EK directly replace an older RX3i Ethernet module? No. Older ETM variants do not support the built-in 2-port switch. You will need to reconfigure the daisy-chain topology settings in Proficy Machine Edition after swapping.
- What’s the maximum safe continuous operating temperature at full 128-connection load? It will hold stable 100Mbps communication up to 60°C, though your mileage may vary if the rack cooling airflow drops below 15 CFM and internal PHY temperatures spike 15°C above ambient.
