Why the BMENOC0301C Matters for Your Control System
When a communication module fails on the plant floor, every connected device can go offline. That is why the Schneider BMENOC0301C is designed to keep your Modicon M580 system talking without interruption. As a maintenance engineer, you need components that are easy to service and built to last. This module delivers on both fronts.
The BMENOC0301C is part of the Modicon M580 range, engineered for modern Ethernet-based architectures. It fits into an Ethernet + X-bus rack, with support for up to four modules per rack. This flexibility lets you scale your network without redesigning your control panel.
Key Technical Specifications at a Glance
Understanding the technical details helps you plan installations and troubleshoot faster. Here are the critical specs for the BMENOC0301C:
- Integrated connection: 3 Ethernet RJ45 ports, 10/100 Mbit/s, double shielded twisted pair
- Communication services: Modbus TCP I/O Scanner and Messaging, EtherNet/IP I/O Scanner and Messaging
- Additional services: Bandwidth management, FDR server, SNMP network administrator, RSTP support, port mirroring, embedded multiport switch, web server
- Current consumption: 900 mA at 3.3 V DC (product version >= 13), 1800 mA at 3.3 V DC (product version < 13)
- Local signaling: LEDs for RUN, ERR, ETH MS, and Eth NS status
- Dimensions: 1.3 in (32 mm) width, 4.08 in (103.7 mm) height, 3.4 in (86 mm) length
- Net weight: 0.4 lb(US) (0.2 kg)
- IP degree of protection: IP20
- Ambient air temperature for operation: 32…140 °F (0…60 °C)
- Protective treatment: Conformal coating
These specifications show a module built for demanding industrial environments. The conformal coating protects against moisture and dust, which is a common cause of premature failure. The wide operating temperature range means you can install it in most factory settings without special cooling.
Built for Reliable Ethernet Networking
The BMENOC0301C supports both Modbus TCP and EtherNet/IP, making it a versatile choice for mixed-vendor environments. With three RJ45 ports, you can daisy-chain devices or create a redundant ring topology using RSTP. This redundancy is critical for minimizing downtime in continuous processes.
The embedded multiport switch reduces the need for external switches, saving panel space and simplifying wiring. The FDR server (Fast Device Replacement) allows quick swapping of failed devices without manual configuration, which is a huge time-saver for maintenance teams. SNMP support lets you monitor network health from a central station, so you can spot issues before they cause production stops.

Real-World Application Scenarios
In a typical packaging line, the BMENOC0301C can connect multiple variable frequency drives and sensors to a single M580 PAC. The Modbus TCP I/O Scanner handles cyclic data exchange, while messaging services allow on-demand reads and writes. This setup reduces wiring and improves data visibility.
For a water treatment plant, the module's RSTP support enables a redundant ring network. If one cable breaks, traffic reroutes in milliseconds, keeping the SCADA system online. The conformal coating also protects against the humid, chemical-laden air common in treatment facilities.
In a machine builder scenario, the web server feature lets you serve a simple status page for remote diagnostics. This helps end customers troubleshoot basic issues without opening the cabinet, reducing service calls.
Compatibility and Integration
The BMENOC0301C is designed for the Modicon M580 platform. It mounts on a BMEXBP... Ethernet + X-bus rack, and you can install up to four modules per rack. Power comes from the rack's internal supply, so no extra wiring is needed.
The module supports standard Ethernet cabling (double shielded twisted pair) and operates at 10/100 Mbit/s, which is compatible with most industrial switches and PLCs. Its certifications include CE, UL, CSA, RCM, EAC, Merchant Navy, ATEX zone 2/22, and IECEx zone 2/22, making it suitable for hazardous locations. Standards compliance includes EN/IEC 61131-2, EN/IEC 61010-2-201, and others, ensuring robust performance.

Business Value: Less Downtime, Lower Costs
Every minute of unplanned downtime costs money. The BMENOC0301C helps reduce that risk with features like FDR and RSTP. Fast device replacement means a failed Ethernet device can be swapped in minutes, not hours. Redundant ring topology keeps the network alive even if a cable is damaged.
The module's low current consumption (900 mA for newer versions) also helps keep power supply loads low, which can extend the life of your power supply and reduce heat in the cabinet. With a net weight of just 0.2 kg, it is easy to handle during installation or replacement.
