Product Overview
The Schneider BMXNOE0100H Modicon M340 Ethernet TCP/IP Network Module is a communication module for integrating a Modicon M340 automation system with Ethernet TCP/IP networks. It provides the network interface needed for exchanging application and diagnostic information between the M340 platform and connected Ethernet devices.
The module is used at the network communication layer of an M340 installation. The PLC processor continues to execute the control application, while the BMXNOE0100H handles communication with external Ethernet equipment such as supervisory computers, operator interfaces, networked controllers, and other automation devices.
In a production or process-control installation, the module can provide an Ethernet communication path between the M340 controller and higher-level or distributed systems. This allows PLC information to be exchanged without placing network communication responsibilities directly on the controller’s local I/O interfaces.
For commissioning and maintenance, the Ethernet network module provides a useful point for checking communication status independently from the PLC’s field I/O. Network connectivity, module status, addressing, cabling, and remote-device availability can be examined when communication problems occur.

Working Principle
The BMXNOE0100H provides the communication path between the Modicon M340 system and connected Ethernet TCP/IP devices. Information generated by the PLC application can be transferred through the network module to external equipment, while incoming network information can be delivered to the M340 environment for use by the control application.
The module handles the network communication interface rather than replacing the processor’s control functions. The M340 CPU remains responsible for executing the application program, while the BMXNOE0100H manages the Ethernet connection used for communication with external systems.
Modicon M340 CPU → BMXNOE0100H → Ethernet TCP/IP Network → HMI / SCADA / Remote Device
Communication performance depends on the complete network path. A fault may originate from the module, Ethernet cabling, network equipment, addressing, configuration, or the remote device. Checking these elements separately helps identify the actual source of a communication problem.
Role in a Modicon M340 Ethernet TCP/IP Control Architecture
The BMXNOE0100H occupies the network communication layer of a Modicon M340 control system. It connects the PLC environment with external Ethernet TCP/IP equipment while the M340 processor continues to execute machine or process-control logic.

Technical FAQs
What is the difference between the BMXNOE0100H and an M340 CPU?
The BMXNOE0100H is a network communication module, while the M340 CPU executes the PLC application and control logic. The two components work together to connect the controller to Ethernet-based systems.
What should be checked if the BMXNOE0100H cannot communicate with a remote device?
Check the module status, Ethernet connection, network equipment, addressing, communication configuration, and remote-device availability. If the physical network is operational, the application-level communication settings should also be reviewed.
Can the BMXNOE0100H be connected directly to an HMI?
It can participate in an Ethernet communication path between the M340 system and an HMI, provided that the network architecture and communication configuration support the intended connection.
Why is the BMXNOE0100H useful in a distributed automation system?
It gives the M340 control system a dedicated Ethernet TCP/IP communication interface, allowing controller information to be exchanged with HMIs, supervisory systems, and other networked automation equipment without using the module as a replacement for the PLC processor.
