Information

Overview Manuals Common Applications Product Precautions

In a Modicon M340 network architecture, Schneider Electric BMXNOC0401 manages controller-to-device exchanges through its integrated industrial Ethernet switch and communication services.

Four-port embedded 10BASE-T/100BASE-TX switch
Modbus TCP and EtherNet/IP scanning and messaging
RSTP, SNMP and port-mirroring services
Transparent Ready class B30 connection

The module is powered internally from the rack and includes RUN, ERR, Ethernet, module-status and network-status indications for commissioning and diagnostics. Preserve the approved IP parameters, scanner tables, topology, firmware and port assignments before exchange. Restore the configuration with the engineering project, then confirm ring state, device connections and controller data exchange under the plant acceptance plan.

Important Notice: Verify the complete BMXNOC0401 identity, Modicon M340 rack position, firmware and recorded Ethernet configuration before installation.

Schneider Electric BMXNOC0401 Official Technical Reference Excerpt (PDF)Schneider Electric BMXNOC0401 Installation & Commissioning Guide (PDF)

The first document contains the applicable manufacturer reference pages for this exact product; the second organizes preparation, wiring, diagnostics and handover checks.

M340 device integration

Links a controller with approved Modbus TCP and EtherNet/IP field devices.

Industrial Ethernet ring

Participates in a documented RSTP topology through the integrated switch ports.

Network diagnostics

Supports status review, SNMP supervision and controlled port mirroring during troubleshooting.

Scanner-led data exchange

Executes saved I/O scanner and messaging tables after the engineering configuration is restored.

Read the applicable Schneider Electric instructions before work. Verify BMXNOC0401 and the installed system configuration before isolation or replacement.

Record the complete Schneider Electric BMXNOC0401 marking and rack position.

Back up the Control Expert project, IP settings and scanner tables before work.

Place the controller and connected process network in the approved maintenance state.

Label all four RJ45 links and document the original switch topology.

Verify firmware, RSTP settings and every EtherNet/IP or Modbus TCP assignment.

Inspect rack connectors, cable latches and shielding before seating the module.

Review RUN, ERR, ETH STS, MS and NS indications after configuration transfer.

Prove every configured device connection and data exchange before release.

Technical notes

Reconcile the saved scanner configuration and network topology before replacing the module. Commissioning should validate both protocol paths, managed-ring behavior and every assigned RJ45 port.
