Introduction
When a Modicon M580 rack loses its Ethernet communication module, the entire plant floor can go dark. The BMENOC0311 from Schneider Electric solves that problem. It is a FactoryCast Ethernet communication module built specifically for the Modicon M580 range. This module restores network connectivity, web-based diagnostics, and I/O scanning without replacing the whole controller.
Engineers choose this module because it integrates directly into the X-bus rack. It draws internal power from the backplane, so no external supply wiring is needed. The result is a fast swap that gets your line back online.
Technical Specifications
The BMENOC0311 packs three Ethernet RJ45 ports rated at 10/100 Mbit/s. Each port uses double shielded twisted pair cabling for noisy industrial environments. The embedded multiport switch lets you daisy-chain devices without extra hardware.
Power comes from the rack backplane. Current consumption depends on product version: 900 mA at 3.3 V DC for version 13 and later, or 1800 mA at 3.3 V DC for earlier versions. Check your rack documentation before ordering.
Four LEDs give instant status: green RUN, red ERR, green/red ETH MS, and green/red Eth NS. These lights cut troubleshooting time because you see processor and network faults at a glance. The module weighs just 0.2 kg and carries an IP20 rating.

Replacement and Upgrade Guide
Angle D applies here. If your existing M580 communication module fails, the BMENOC0311 is the direct drop-in replacement. You do not need to change the rack, rewire power, or reprogram the CPU. The module slides into the Ethernet plus X-bus rack and draws power internally.
Before ordering, confirm your product version. Version 13 and later draw 900 mA at 3.3 V DC. Earlier versions draw 1800 mA at 3.3 V DC. Matching the correct version prevents backplane overload and keeps your warranty valid.
SpareTechPLC stocks this module with returnability available. That policy reduces your risk if the version does not match your rack.
Compatibility and Integration
The BMENOC0311 works with BMEXBP Ethernet plus X-bus racks. It supports Modbus TCP I/O Scanner and Messaging, plus Ethernet/IP I/O Scanner and Messaging. RSTP support lets you build redundant ring topologies for critical processes.
FactoryCast configurable web services give you remote diagnostics through a standard browser. SNMP network administration and bandwidth management help IT and OT teams share the same network safely. Port mirroring aids network troubleshooting without disrupting production.
Installation and Setup
Mounting is straightforward. Slide the module into the rack until the connector seats. The backplane supplies all power, so you only connect your Ethernet cables to the RJ45 ports.
After power-up, watch the LEDs. A solid green RUN light means the processor is running. A red ERR light signals a fault. The ETH MS and Eth NS lights show port and network status. Use these indicators to verify correct seating and cable integrity before calling for support.
Maintenance and Reliability
The IP20 rating means this module belongs inside a clean cabinet. Keep ambient air between 0 °C and 60 °C. Inspect the RJ45 connectors periodically for dust or bent pins. Check that cabinet fans run correctly, because heat shortens module life.
For ROI, remember that one spare BMENOC0311 on the shelf can prevent hours of downtime. The 0.2 kg weight and compact package make storage easy. Follow Schneider’s safety manual for all service work. Do not open the housing.
