When Your M340 Rack Needs a Faster Data Path
Plant engineers running Modicon M340 systems often hit a wall when legacy serial links slow down production reporting. The BMXNOE0110 solves that problem directly. This Schneider Ethernet TCP/IP network module plugs into the M340 rack and gives your PLC a transparent-ready Class C30 connection over a standard RJ45 twisted pair at 10/100 Mbit/s.
What the Module Actually Delivers
The BMXNOE0110 is not just a port. It is a full communication engine. Schneider ships it with a supplied flash memory card (BMXRWSC016M) and 16,000 kB of internal RAM. That memory split matters: the flash card stores your application and standard web server pages, while RAM handles user web page size and runtime data. You get a configurable web server, an FDR server, SNMP network administration, and SOAP XML web services in one standard-format module.
Technical Specs That Drive Uptime
Three parameters separate this module from generic Ethernet cards.
Current draw of 90 mA at 24 V DC keeps rack power budgets predictable. You can add multiple BMXNOE0110 modules without upgrading the supply.
The 0…60 °C operating range covers most control cabinets. Combined with 10…95 % relative humidity without condensation and IP20 protection, the module survives real factory floors, not just clean labs.
Six diagnostic LEDs turn troubleshooting into a visual check. Green LEDs report Ethernet activity, processor run status, and network status. Red LEDs flag data rate, memory card faults, and processor or system errors. A RESET push-button handles cold restarts on the spot.
Solving the Integration Headache
Most M340 upgrades stall because the new module will not talk to existing SCADA or HMI layers. The BMXNOE0110 avoids that trap. It supports Modbus TCP messaging, I/O scanning, global data exchange, and bandwidth management. Your existing Modbus TCP master keeps working. Your web-based dashboards keep pulling data. The Data Editor works from a PC, pocket PC, or PDA terminal.
Where This Module Earns Its Place
Water treatment plants use it to push tank levels and pump status to a central SCADA screen over Ethernet, replacing slow serial polling.
Food packaging lines rely on the web server to let maintenance techs check I/O status from a tablet without opening the cabinet.
Energy substations benefit from SNMP administration, letting network teams monitor the module alongside other managed switches.
Installation and Setup
Mount the BMXNOE0110 in a standard M340 rack slot. Power comes internally from the rack, so no separate supply wiring is needed. Connect the RJ45 port to your 10BASE-T or 100BASE-TX network. Use the RESET push-button for cold restarts after firmware or configuration changes. Follow Schneider’s M340 platform manual for rack addressing and IP configuration.
Maintenance That Protects Your Investment
Check the six LEDs during routine rounds. A red CARD ERR LED points to a flash card issue. A red ERR LED signals a processor or system fault. Inspect the RJ45 connector for strain or corrosion every few months. Keep cabinet temperature within the 0…60 °C range. Verify current draw stays near 90 mA at 24 V DC if you add modules. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Selection Checklist
Confirm your rack is a Modicon M340 automation platform. Verify you need transparent-ready Class C30 service. Check that your network uses 10BASE-T or 100BASE-TX. The module carries CE marking and meets 2014/35/EU low voltage and 2014/30/EU EMC directives. It ships at 0.2 kg in a standard module format. SpareTechPLC stocks this module and can confirm fitment for your specific M340 configuration.
Frequently Asked Questions
Does the BMXNOE0110 include the flash memory card?
Yes. Schneider supplies the BMXRWSC016M flash memory card with the module. It stores the application and standard web server pages.
Can I use this module for Modbus TCP messaging?
Yes. The BMXNOE0110 supports Modbus TCP messaging, I/O scanning, global data, and bandwidth management as standard communication services.
What is the power consumption?
The module draws 90 mA at 24 V DC, supplied internally through the M340 rack.
What do the red LEDs indicate?
Red LEDs show data rate (ETH 100), memory card faults (CARD ERR), and processor or system faults (ERR).
What is the operating temperature range?
The BMXNOE0110 operates from 0…60 °C with 10…95 % relative humidity without condensation.
