Upgrade Your Modicon M340 with the BMXNOE0100 Ethernet Module
Is your Modicon M340 PLC still relying on serial communication? The BMXNOE0100 from Schneider Electric solves that problem. This TCP/IP Ethernet network module plugs directly into the M340 rack and adds a 10/100 Mbit/s RJ45 port. It belongs to the Transparent Ready concept, so your controller joins plant networks without complex gateways. The module draws only 90 mA at 24 V DC from the rack’s internal supply.
Key Specifications That Matter
Ethernet Connectivity
The integrated RJ45 port supports 10BASE-T and 100BASE-TX. One twisted pair connects the module to your network. The Class B30 rating defines its bandwidth capability within the Transparent Ready architecture.
Communication Services
The BMXNOE0100 runs a configurable web server, SNMP network manager, and FDR server. It handles Modbus TCP messaging, global data exchange, and I/O scanning. A supplied flash card (BMXRWSC016M) stores application programming.
Diagnostics and Control
Six LEDs show Ethernet activity, processor run state, network status, data rate, card errors, and system errors. A RESET button enables cold starts. The module weighs just 0.2 kg and operates from 0 to 60 °C at 10 to 95 % relative humidity, non-condensing. Its IP20 rating suits cabinet installation.
Compliance
The module complies with 2014/35/EU (Low Voltage Directive) and 2014/30/EU (Electromagnetic Compatibility). CE marking confirms conformity.
Comparison: BMXNOE0100 vs. Other M340 Communication Options
| Feature | BMXNOE0100 (Ethernet TCP/IP) | Typical Serial Module |
|---|---|---|
| Protocol | Modbus TCP, Ethernet TCP/IP | Modbus RTU/ASCII |
| Port | RJ45 10/100 Mbit/s | RS-232/RS-485 |
| Web Server | Configurable | Not available |
| I/O Scanning | Yes | No |
| SNMP Manager | Yes | No |
| Data Rate | 10/100 Mbit/s | Up to 115.2 kbit/s |
This comparison shows why the BMXNOE0100 suits modern networked plants. Serial modules still serve legacy devices, but Ethernet delivers faster data exchange and remote visibility.
Where the BMXNOE0100 Fits
Factory Floor Data Collection
I/O scanning lets the module poll remote devices and feed data to the M340 processor. Production dashboards update in real time.
Remote Diagnostics
The web server and SNMP manager allow engineers to check module status from any networked PC. Maintenance teams diagnose faults without opening cabinets.
Legacy System Upgrades
Plants replacing older serial networks can add the BMXNOE0100 to an existing M340 rack. The module uses the rack’s internal power supply, so no external wiring is needed.
Installation and Setup
Mount the module in any available M340 rack slot. The rack supplies power through the backplane. Connect the RJ45 port to your network switch using a standard twisted-pair cable. Insert the supplied flash card (BMXRWSC016M) before powering up. Use the RESET button for a cold start after configuration changes. Verify LED status: green for normal operation, red for faults.
Maintenance and Reliability
Inspect the module periodically for dust buildup and secure connections. The IP20 rating requires a clean, dry cabinet environment. Operating temperature must stay between 0 and 60 °C. Relative humidity must remain between 10 and 95 %, non-condensing. Check the flash card seating if CARD ERR LED lights. Follow Schneider Electric’s safety manual for all maintenance activities.
Compatibility and Integration
The BMXNOE0100 works exclusively with the Modicon M340 automation platform. It communicates via Modbus TCP messaging and Ethernet TCP/IP. The module integrates with SCADA systems, HMI panels, and plant historians through its web server and SNMP support. FDR server functionality enables device replacement without reprogramming.
Selection Guide
Before ordering, verify your rack has an available slot and sufficient power budget. The module consumes 90 mA at 24 V DC. Confirm your network supports 10BASE-T or 100BASE-TX. You need a standard RJ45 twisted-pair cable. The supplied flash card (BMXRWSC016M) comes with the module. Contact SpareTechPLC for availability and replacement options. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Frequently Asked Questions
What communication protocols does the BMXNOE0100 support?
It supports Modbus TCP messaging, Ethernet TCP/IP, SNMP, and global data exchange. The web server is configurable.
Can I use this module in a new M340 installation?
Yes. It fits any M340 rack slot and uses the rack’s internal power supply.
What is the power consumption?
The module draws 90 mA at 24 V DC from the rack backplane.
How do I know if the module is working?
Check the LEDs. Green indicates normal operation. Red signals faults like card errors or system errors.
What environmental conditions does it require?
Operate between 0 and 60 °C at 10 to 95 % relative humidity, non-condensing. The IP20 rating requires a protected cabinet.
