Schneider Electric BMXNOC0401 – Modicon M340 Ethernet TCP/IP Network Communication Module
Engineering Background: The BMXNOC0401 is Schneider Electric’s dedicated Ethernet TCP/IP communication module for the Modicon M340 mid-range PLC platform — one of the most widely deployed automation controllers in process, discrete, and hybrid manufacturing environments worldwide. Designed to integrate seamlessly into the M340 backplane, this module extends the controller’s connectivity to plant-level SCADA systems, HMI panels, and enterprise MES/ERP networks via standard 10/100 Mbps Ethernet.
Product Positioning: Targeted at automation engineers and system integrators who require deterministic, high-throughput Ethernet communication in demanding industrial environments. The BMXNOC0401 supports Modbus TCP/IP and EtherNet/IP protocols, enabling interoperability with third-party devices and multi-vendor architectures. It is the preferred choice for brownfield upgrades and greenfield M340 deployments requiring network-level diagnostics and remote I/O management.

- Modbus TCP/IP & EtherNet/IP dual-stack: Interoperates natively with Rockwell, Siemens, and third-party devices on the same network segment.
- Hot-swap capable: Module replacement without full system shutdown minimizes production downtime during maintenance windows.
- Unity Pro / EcoStruxure Control Expert native: Zero-configuration discovery and parameterization within Schneider’s engineering environment.
- SNMP v1/v2c support: Integrates into enterprise IT network management infrastructure for centralized asset monitoring.
System Architecture & Signal Flow
The BMXNOC0401 occupies one slot on the Modicon M340 backplane (BMX XBP xxxxx rack). The module communicates with the CPU (e.g., BMXP342020, BMXP342030) via the X-Bus backplane at full bus speed. On the network side, the dual RJ45 ports connect to plant Ethernet infrastructure. Data flow: Field I/O → M340 CPU → BMXNOC0401 → Ethernet switch → SCADA/HMI/MES. The embedded web server (port 80) and FTP server (port 21) allow direct file transfer of data logging and configuration backups. Modbus TCP/IP server (port 502) handles real-time polling from SCADA clients at configurable scan rates.
Sourcing & Quality Verification
- All units sourced from authorized Schneider Electric distribution channels or verified industrial surplus with full traceability.
- Each module undergoes incoming inspection: visual check, label verification (part number, date code, country of origin), and functional power-on test.
- Firmware version documented and provided with shipment.
- Original packaging preserved where available; anti-static ESD packaging used for all shipments.
- Certificate of conformity available upon request for regulated industries.
Procurement Process

Technical FAQ
Q: Is BMXNOC0401 compatible with all M340 CPUs?
A: Yes, it is compatible with all Modicon M340 CPU modules (BMXP34xxxx series) and all standard M340 racks. Verify rack slot availability before ordering.
Q: Can BMXNOC0401 replace BMXNOE0100 / BMXNOE0110?
A: The BMXNOC0401 is a different product line (communication module vs. network option module). Consult Schneider Electric’s compatibility matrix or contact Konmask engineering support for migration guidance.
Q: What Unity Pro / Control Expert version is required?
A: Unity Pro v4.0 or later (EcoStruxure Control Expert v14.0+) is recommended for full feature support including web server configuration and SNMP setup.
Q: Does the module support DHCP?
A: Yes, DHCP client is supported. Static IP assignment is also available and recommended for production environments to ensure deterministic addressing.
Q: What is the warranty?
A: Konmask provides a 90-day functional warranty on all modules. Extended warranty and on-site support available upon request.
