Schneider Electric BMENOC0301C Modicon M580 Ethernet Communication Module

Schneider Electric BMENOC0301C Modicon M580 Ethernet Communication Module

Configured for Ethernet communication between Modicon M580 controllers and network devices, the Schneider Electric BMENOC0301C (BMENOC0301C communication module) provides Modbus TCP and EtherNet/IP interface functions through three Ethernet ports.

Hardware Specifications

M580 Ethernet Network and Backplane Communication

The BMENOC0301C occupies one Ethernet + X-bus slot on the M580 main rack. It receives power through the rack internal power system and communicates through the Ethernet backplane.

Three RJ45 ports support 10/100 Mbit/s Ethernet communication. The integrated multi-port switch supports RSTP, port mirroring, bandwidth management, and Ethernet network services.

Modbus TCP I/O scanning and messaging, together with EtherNet/IP I/O scanning and messaging, provide controller-to-device data exchange. SNMP supports network management, while the FDR server provides device replacement-related network services.

The module supports M580 standalone CPUs, redundant CPUs, compatible safety CPUs, and X80 racks equipped with an Ethernet backplane.

Frequently Asked Questions (FAQ)

Q: How is the BMENOC0301C powered when installed in an M580 rack?
A: The module receives its operating power from the internal power distribution of the rack.

Q: What Ethernet interfaces are provided by the BMENOC0301C?
A: The module provides three RJ45 Ethernet ports supporting 10/100 Mbit/s transmission through double-shielded twisted-pair cabling.

Q: Does the BMENOC0301C support hot-swapping or field firmware replacement?
A: The supplied information does not specify hot-swap or firmware replacement conditions. Installation and firmware procedures should follow the applicable Schneider Electric documentation for the module revision.

Field Installation Guidelines

Install the BMENOC0301C in the designated Ethernet + X-bus position of the M580 main rack and secure the module according to the rack installation procedure.

Use shielded Ethernet cabling compatible with the RJ45 interfaces. Maintain physical separation between Ethernet cables and high-current, switching, or high-noise power conductors.

Terminate cable shields according to the system grounding design and Schneider Electric installation instructions. Avoid creating unintended shield-current paths between separately grounded equipment.

Verify rack power availability before insertion or removal. Confirm the module revision when applying the specified 3.3 VDC backplane current requirement.

After installation, inspect the RUN, ERR, ETH MS, and ETH NS indicators to verify processor, module, port configuration, and network status.

For installations in ATEX or IECEx Zone 2/22 environments, apply the applicable hazardous-location installation requirements and certified system configuration.
