More Information

Overview Manuals Network Services Firmware & Project Network Diagnostics Product Applications

Features:

  • Four-port Ethernet: four 10/100BASE-T RJ45 interfaces support controller, device and service connections.
  • Dual industrial protocols: supports Modbus TCP and EtherNet/IP communication.
  • Managed network services: includes RSTP, port mirroring, FDR, SNMP and web diagnostics.
The module combines an M340 rack interface with a four-port industrial Ethernet switch.

Firmware 2.01 or later adds the documented SMTP and NTP services represented by the BMXNOC0401.2 catalogue entry.

A successful exchange restores the saved network plan, I/O scan and project diagnostics without duplicate addressing or unintended topology changes.

Apter Power supports Schneider Electric BMXNOC0401 Ethernet TCP/IP Network Module quotations, technical documentation, procurement support and system-matching guidance.
Schneider Electric BMXNOC0401 Ethernet TCP/IP Network Module Manuals,Datasheets,Link Important Notice: Apter Power provides these resources for exact-model documentation, quotation and engineering review.
  • Modbus TCP: supports client and server messaging for compatible devices.
  • EtherNet/IP: supports documented I/O scanning and explicit messaging.
  • Switching: four 10/100 RJ45 ports provide the local network interface.
  • Resilience: RSTP supports a managed redundant topology.
  • Firmware boundary: version 2.01 or later is represented as BMXNOC0401.2.
  • Added services: the later firmware supports SMTP and NTP.
  • CPU fit: use a supported BMXP342-series CPU and matching Control Expert catalogue.
  • Project record: retain IP, scan and communication settings before exchange.
  • Port state: check link, speed and error counters for each used connection.
  • Address review: exclude duplicate IP addresses before reconnecting field devices.
  • I/O scan: compare configured devices with live connection status.
  • Recovery proof: test RSTP, web diagnostics and controller communications after restart.
  • M340 distributed I/O: exchanges cyclic data with supported EtherNet/IP or Modbus TCP devices.
  • Controller integration: links an M340 rack with supervisory, peer and service networks.
  • Managed ring networks: uses RSTP where the documented topology requires resilience.
  • Maintenance access: provides diagnostic web, SNMP and port-mirroring support for network troubleshooting.
Description
BMXNOC0401 connects a Modicon M340 rack to industrial Ethernet through four 10/100BASE-T RJ45 ports. It supports Modbus TCP and EtherNet/IP communication while the integrated switch keeps controller, device and service connections within one module.

The installed role of BMXNOC0401 can include I/O scanning, explicit messaging, RSTP, port mirroring, FDR, SNMP and the embedded diagnostic web server. Firmware and the Control Expert hardware catalogue determine which services are available to the project.

When replacing BMXNOC0401, retain the IP plan, switch topology, scan list and application backup. Schneider identifies BMXNOC0401.2 as the same hardware with firmware 2.01 or later; the project and firmware boundary should therefore be reviewed together before restart.
Alternative Names

Technical notes
BMXNOC0401 firmware 2.01 or later is represented in Control Expert as BMXNOC0401.2 and adds documented SMTP and NTP services. Treat that catalogue entry as a firmware boundary for the same hardware, then verify the M340 CPU, project version, IP addressing, I/O scan and network recovery behavior before returning the rack to automatic control.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can BMXNOC0401 connect both Modbus TCP and EtherNet/IP devices in the same Modicon M340 project?
Yes, when the Control Expert project, CPU capacity and scan resources are engineered for both services. Apter Power can help review the documented network scope before quotation.
What does BMXNOC0401.2 mean when it appears in Control Expert?
It represents BMXNOC0401 hardware with firmware 2.01 or later. The later entry adds documented SMTP and NTP functions, so the project catalogue and firmware should agree.
Which records help replace BMXNOC0401 without losing the installed network configuration?
Keep the Control Expert backup, firmware version, IP plan, RSTP settings, I/O scan list and port assignments with the service record.
Why can BMXNOC0401 show link lights while remote I/O remains disconnected?
A physical link does not confirm the IP address, device identity, scan mapping or connection resources. Review module diagnostics and the project scan list together.
How should an RSTP fault be investigated on BMXNOC0401?
Compare the intended ring topology, port roles and switch configuration, then inspect each link for unexpected loops, blocked ports or unstable connections.
When is BMXNOC0401 ready to return to automatic operation after replacement?
Release it after the rack is healthy, addresses are unique, all required I/O connections are established and the documented network-recovery test passes.
