Product Overview

The Schneider BMXNOC0401 is an Ethernet communication module designed for the Modicon M340 automation platform. It supports EtherNet/IP and Modbus TCP communication and provides four RJ45 10/100 Ethernet ports for industrial network integration.

The module is used when an M340 system requires communication with EtherNet/IP devices, Modbus TCP equipment, distributed I/O, variable speed drives, HMI panels, supervisory systems or other compatible Ethernet nodes.

The BMXNOC0401 is particularly important in M340 applications because standard BMXNOE modules do not provide the same EtherNet/IP capability. The complete commercial reference must therefore be checked before replacement.

Technical Specifications

Compatible System and Applications

The BMXNOC0401 is suitable for Modicon M340 systems communicating with EtherNet/IP remote I/O, compatible drives, intelligent motor-control devices, industrial Ethernet equipment, HMI panels and supervisory systems.

It can also be used in Modbus TCP architectures requiring data exchange between the M340 application and compatible Ethernet devices. Scanner configuration, communication instances, data sizes and update rates must be reviewed against the original Control Expert project.

The four-port network arrangement can support flexible machine-network layouts. The actual network topology, managed-switch requirements, redundancy strategy and permitted port use must be verified before installation.

Maintenance and Replacement Notes

Verify the complete BMXNOC0401 reference. BMXNOE0100 and BMXNOE0110 support Modbus TCP but do not provide the same EtherNet/IP functionality.

Before removing the original module, record the IP address, subnet mask, gateway, EtherNet/IP device configuration, Modbus TCP scanner tables, DTM configuration, firmware and rack-slot position.

A replacement module may require firmware alignment, application download, DTM restoration and revalidation of every connected Ethernet device.

Do not assume that the module will operate after physical installation without restoring the original Control Expert communication configuration.

Related Models

Related communication modules include BMXNOE0100 for standard Modbus TCP communication, BMXNOE0110 for FactoryCast Ethernet functions and BMXNOM0200 for RS-232 or RS-485 serial communication.

BMXP342020 and BMXP3420302 are M340 processor modules with embedded Ethernet positioning, but their communication resources and network architecture differ from a separate BMXNOC0401 module.

Inquiry and Supply Notes

Please provide the complete module reference, M340 CPU model, rack reference, slot position, firmware revision, Ethernet topology, EtherNet/IP device list, Modbus TCP scanner configuration and Control Expert project status.

Product condition, firmware compatibility, communication testing, port testing, regional availability and delivery time must be confirmed before quotation.
