Schneider Electric BMENUA0100 Modicon M580 Communication Module

Configured for OPC UA client communication and IT network data exchange in the Modicon M580 platform, the Schneider Electric BMENUA0100 (BMENUA0100 communication module) provides an embedded OPC UA server with Ethernet connectivity, backplane transparency, and diagnostic communication services.

Hardware Specifications

Modicon M580 Ethernet and OPC UA Communication

The BMENUA0100 occupies one Ethernet/X-bus rack slot and communicates through the M580 Ethernet backplane. Its front Ethernet interface supports 10/100/1000 Mbit/s operation. The embedded OPC UA server supports up to 10 client connections, with up to 40 subscriptions per session.

Standard OPC UA operation provides a minimum publishing interval of 250 ms and a minimum sampling interval of 125 ms. Fast sampling supports a 20 ms minimum sampling interval and 20 ms minimum publishing interval. The module supports up to 100,000 OPC UA nodes.

Network functions include IPv6, IP forwarding, service forwarding, network segmentation, Modbus TCP diagnostics, SNMP V1/V3 network management, and NTP V4 time synchronization. Security functions include HTTPS, certificate-based authentication, role-based access control, Syslog, IPSec, built-in firewall functions, and network physical isolation.

Frequently Asked Questions

Q: Can the BMENUA0100 be installed while the M580 rack remains powered?

A: Yes. The module supports hot swapping and configuration changes on the fly. Installation and replacement must follow the applicable M580 rack installation procedure.

Q: What is the electrical load of the BMENUA0100 on the rack power supply?

A: The specified current consumption is <= 140 mA at 24 VDC from the internal rack power supply.

Q: What Ethernet connection is provided for OPC UA communication?

A: The module provides one RJ45 Ethernet port supporting 10/100/1000 Mbit/s over double-shielded twisted-pair cabling. Ethernet backplane communication provides transparency between the module and connected M580 system components.

Field Installation Guidelines

Install the BMENUA0100 in an Ethernet or X-bus slot of the main rack, within the supported M580 X80 Ethernet backplane configuration. The module occupies one rack slot, with a maximum of two BMENUA0100 modules permitted per rack.

Route Ethernet cabling separately from high-voltage power conductors and high-current switching circuits where practical. Use the specified shielded twisted-pair Ethernet connection and maintain appropriate cable routing and bend-radius practices.

Connect the module only to the supported rack power system. Verify the rack power budget before installation, accounting for the module's <= 140 mA current consumption at 24 VDC.

Before commissioning OPC UA communication, configure IP addressing, network segmentation, certificates, user roles, and applicable firewall or IPSec functions according to the M580 cybersecurity configuration. Check the RUN, ERR, ETH MS, ETH NS, STS, and communication bus LEDs during startup and commissioning.

The module is rated IP20 and should therefore be installed inside the appropriate control enclosure. Maintain the specified 0 to 60 deg C operating temperature and avoid installation locations exposed to condensation or conductive contamination.
