BMXNOE0110H | Schneider Electric Ethernet TCP/IP Module M340

Why the BMXNOE0110H Belongs in Your M340 Rack

When a Modicon M340 station needs to talk to the plant network, the BMXNOE0110H is the module engineers specify. This Schneider Electric Ethernet TCP/IP network module turns a standard M340 rack into a Transparent Ready Class C30 server, giving your PLC a 10/100 Mbit/s RJ45 twisted-pair connection with a conformal coating for severe environments.

If you are replacing a failed network card or building a new panel, downtime is the enemy. SpareTech Plc keeps genuine parts in stock and ready to ship, so your line gets back online without a procurement marathon.

Key Parameters That Matter on the Floor

• Integrated connection: Ethernet TCP/IP RJ45, 10/100 Mbit/s, 1 twisted pair, Transparent Ready Class C30
• Port support: 10BASE-T / 100BASE-TX

• Memory: internal RAM 16,000 kB; supplied Flash memory card BMXRWSC016M for web pages, application saving and standard web server activation
• Supply: internal power supply via rack; current consumption 90 mA at 24 V DC
• Protective treatment: conformal coating
• Operating temperature: -13…158 °F (-25…70 °C)
• Relative humidity: 10…95 %, without condensation
• IP degree of protection: IP20
• Net weight: 0.4 lb (US) (0.2 kg); standard module format

Diagnostics You Can Read at a Glance

Six front LEDs keep troubleshooting honest: green ETH ACT for network activity, green RUN for processor running, green ETH STS for network status, red ETH 100 for data rate, red CARD ERR for memory card faults, and red ERR for processor or system faults. A RESET push-button handles cold restart.

Where This Module Earns Its Keep

Severe-environment panels are the BMXNOE0110H's home turf. The conformal coating plus gas, dust, sand, salt, mold and fungal-spore resistance ratings suit wastewater plants, food processing areas and coastal installations. In a retrofit project, this module lets an existing M340 rack join a plant-wide supervisory network without replacing the controller — a cost-effective upgrade path compared with a full platform change.

Typical duties include I/O scanning between racks, Modbus TCP messaging to drives and HMIs, and serving web pages for remote diagnostics.

Integration Note

Wiring into an existing Ethernet architecture may require an external gateway or connection module depending on your topology. Confirm cables, switches and gateway choices with your supplier before commissioning.

Selection Advice Before You Order

Confirm your rack is a Modicon M340 automation platform, verify you need the Class C30 Transparent Ready feature set, and check that your enclosure meets the IP20 requirement. The module carries CE, UL, CSA, RCM, EAC, Merchant Navy and ATEX/IECEx zone 2/22 certifications, with marking CE and compliance to IEC 61131-2 and UL 61010-2-201 among others.

Please verify current lifecycle status and availability with SpareTech Plc before ordering. Our technical team helps match the right network module to your application.

Reliability and Uptime

Inspect the RJ45 connection and LED behaviour periodically, keep the cabinet within the stated temperature and humidity window, and follow the manufacturer's safety manual for all maintenance. Because the module draws only 90 mA at 24 V DC, it adds negligible load to your rack supply.
