When Your M340 Rack Needs to Speak Ethernet
A system integrator once faced a familiar problem: a Modicon M340 rack was running production data locally, but the plant’s SCADA layer needed that data over Ethernet. The rack had no native TCP/IP port. Adding a gateway would mean extra wiring, extra configuration, and another failure point. The solution was simple: plug the Schneider BMXNOE0110 Ethernet TCP/IP network module directly into the rack.
This module belongs to the Modicon M340 automation platform and carries the Transparent Ready concept. It provides one RJ45 Ethernet TCP/IP port rated at 10/100 Mbit/s over twisted pair, Transparent Ready class C30. That single port turns a standalone rack into a networked node without external converters.
What the BMXNOE0110 Delivers
The BMXNOE0110 is an Ethernet TCP/IP network module with a supplied flash memory card (BMXRWSC016M) and 16000 kB internal RAM. It draws 90 mA at 24 V DC through the rack’s internal power supply. The module uses a standard format and weighs 0.2 kg.
Communication Services Built In
The module supports bandwidth management, an FDR server, Rack Viewer, SNMP network administration, Global Data, I/O scanning, Modbus TCP messaging, a configurable web server, Data Editor access via PC, pocket PC, or PDA terminal, and a SOAP XML Web service server. These services cover the common needs of a networked control system: data exchange, diagnostics, and remote configuration.
Memory and Web Server
The supplied flash memory card handles user web page size in internal RAM, activation of the standard web server, and application saving. This design keeps web content and application data on removable storage while using internal RAM for runtime operations.

Where the BMXNOE0110 Fits
Factory Floor Data Collection
A production line with a Modicon M340 rack can send I/O data and diagnostics to a supervisory system using Modbus TCP messaging and I/O scanning. The web server allows maintenance staff to view Rack Viewer pages from a standard browser.
Remote Diagnostics and Configuration
With SNMP network administration and the Data Editor, engineers can check module status and adjust parameters without opening the cabinet. The SOAP XML Web service supports integration with higher-level IT systems.
Upgrade Path for Legacy Racks
Plants running older M340 racks without Ethernet can add the BMXNOE0110 to gain network access. The module uses the rack’s internal power supply, so no separate power wiring is required.
Installation and Setup Notes
Mount the module in a standard M340 rack slot. The rack provides internal power at 24 V DC, and the module consumes 90 mA. Connect the RJ45 port to an Ethernet switch or directly to a programming terminal. Use the RESET push-button for a cold restart when needed. Verify that the supplied flash memory card (BMXRWSC016M) is seated properly before power-up. The module operates in ambient temperatures from 0…60 °C and relative humidity from 10…95 % without condensation. Keep the enclosure rating at IP20, which means the module must live inside a protected cabinet.
Maintenance and Reliability
Check the six LEDs regularly. The green ETH ACT LED shows Ethernet activity. The green RUN LED shows processor operation. The green ETH STS LED shows Ethernet status. The red ETH 100 LED shows data rate. The red CARD ERR LED shows a memory card fault. The red ERR LED shows a processor or system fault. A red LED is your first clue for troubleshooting. Inspect the RJ45 connector and cable for wear. Keep the cabinet within the specified temperature and humidity range. The module has no moving parts, so wear is minimal. Follow the manufacturer’s safety manual for all maintenance activities.
Compatibility and Integration
The BMXNOE0110 works within the Modicon M340 automation platform. It supports Modbus TCP messaging, which is common in industrial networks. The web server and Data Editor allow configuration from a PC, pocket PC, or PDA terminal. SNMP support lets network administrators monitor the module alongside other network devices. The SOAP XML Web service enables data exchange with enterprise systems.
Selection Guide
Before buying, confirm that your rack is a Modicon M340 platform and that you have a free standard slot. Verify that your network uses Ethernet TCP/IP at 10/100 Mbit/s. Check that you need the communication services listed above. The module ships with a flash memory card (BMXRWSC016M). If you need spare parts or want to confirm availability, contact SpareTechPLC. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
