Schneider Electric BMENOC0301 – Ethernet Network Module for Modicon M580 to connect Modbus TCP / EtherNet/IP devices
The Schneider Electric BMENOC0301 is the go-to Ethernet network module for Modicon M580 ePAC systems when you need clean, reliable connectivity to field devices and SCADA. From my experience, it’s the piece you add when the built‑in CPU port isn’t enough—whether you’re segmenting machine networks, adding a dedicated device network, or you want web-based diagnostics without touching the control CPU. It typically handles Modbus TCP and, in many cases, EtherNet/IP integration on the device side, so you can standardize one module across different plants.

Key Features
- Designed for Modicon M580 backplane – Slides into the X80 rack and is powered via the backplane, no external PSU wiring required.
- Three RJ45 Ethernet ports (10/100 Mbps) – You might notice two switched device ports plus a service/engineering port, handy for segregating traffic.
- Industrial protocols – Typically supports Modbus TCP and, in many cases, EtherNet/IP integration for drives, HMIs, and third‑party devices.
- Embedded web diagnostics – Real-time status, network counters, and basic troubleshooting from any browser on the control network.
- Network resiliency – RSTP ring participation is commonly used to keep lines running through a switch or cable fault.
- IT-friendly services – DHCP/BOOTP, SNMP monitoring, and simple addressing make it easier to fit into plant standards.
- Tight integration with EcoStruxure Control Expert – Configuration and diagnostics straight from your M580 project environment.
- Status LEDs front-facing – Quick glance link/activity and module health reduces time with a multimeter.

Application Fields
You’ll typically see BMENOC0301 added where the M580 needs its own device network: packaging lines, water/wastewater plants, conveying systems, and energy skids. It works well for:
- Connecting VFDs, remote I/O, and HMIs over Modbus TCP or EtherNet/IP
- Segregating SCADA traffic from machine‑level devices for better determinism
- Building RSTP rings across machines without needing an extra managed switch
- Brownfield upgrades where the control CPU ports are already fully utilized
Feedback from a maintenance lead at a beverage facility: “Adding the NOC gave us a clean device network; the web page saved an hour of guesswork when a contractor mis‑patched a drive.”
Advantages & Value
- Reliability – Industrial‑grade ports and proven M580 ecosystem. It appears to be less fussy than standalone NICs in harsh cabinets.
- Compatibility – Works natively with Control Expert projects; typical protocol support covers most common plant devices.
- Cost control – Reduces the need for a separate managed switch for small cells; fewer components to stock.
- Support & lifecycle – Schneider Electric documentation and firmware track the M580 platform, making long‑term maintenance straightforward.
Installation & Maintenance
- Panel & rack – Install in a clean, ventilated enclosure meeting typical industrial cabinet standards; allow airflow above/below the rack.
- Wiring – Use shielded industrial Ethernet (Cat5e/6) for device ports; maintain proper grounding and cable separation from motor power.
- Network layout – If you implement RSTP, verify ring priorities and test a link‑loss scenario; keep service port for engineering access.
- Firmware & config – Keep module firmware aligned with your M580 project version; update via EcoStruxure Control Expert as part of routine maintenance.
- Routine checks – Review diagnostic counters quarterly (CRC errors, drops) and clean dust from the cabinet; check connector strain reliefs.
- Cyber hygiene – Change default passwords, restrict web access to engineering VLANs, and document IP addressing conventions.
Quality & Certifications
- Manufacturer compliance typically includes CE, UL, CSA, and RoHS (check your specific firmware/hardware revision datasheet)
- Standard Schneider Electric warranty applies; we provide a 365‑day warranty on supply
Recommended Accessories & Compatible Components
- BMEXBP-series backplanes (slot count as required)
- BMXCPS or BMEXBP power supply modules sized for total rack load
- ConneXium industrial Ethernet switches for larger rings or VLAN segmentation
- Industrial shielded RJ45 patch cords and panel feed‑throughs for cabinet integrity
