Product Overview
The BMENOC0311 is a FactoryCast Ethernet communication module from Schneider Electric, built for the Modicon M580 automation platform. It plugs into an Ethernet plus X-bus rack and turns a standard controller chassis into a networked node with three RJ45 ports. Each port runs at 10/100 Mbit/s over double shielded twisted pair cable, so you can segment traffic without adding external switches. The module draws power directly from the rack, which keeps cabinet wiring simple and reduces installation time.
Key Parameters That Shape Performance
Three integrated RJ45 ports form an embedded multiport switch. This design lets you daisy-chain devices or build redundant ring topologies without extra hardware. The module supports RSTP, so a broken link in a ring network recovers automatically instead of stopping production.
Power comes from the backplane. Current consumption is 900 mA at 3.3 V DC for product version 13 and above, or 1800 mA at 3.3 V DC for earlier versions. Always confirm the module revision before you calculate rack load.
Four LEDs report status at a glance: RUN (green), ERR (red), ETH MS and Eth NS (green/red). Technicians can diagnose processor faults and network health without opening a laptop.
FactoryCast configurable web services and an embedded web server let you view diagnostics and manage bandwidth from a browser. The module also acts as an FDR server and SNMP network administrator.
Where the BMENOC0311 Fits in Real Plants
Water treatment upgrade. A plant running an older M580 rack needs plant-floor data in the SCADA layer. The BMENOC0311 adds Modbus TCP I/O Scanner and Messaging plus Ethernet/IP I/O Scanner and Messaging on the same module. You connect flow meters, VFDs, and remote I/O without a separate gateway.
Replacement and upgrade path. When a legacy communication card fails, downtime costs far more than the part. This module restores FactoryCast web diagnostics and RSTP ring recovery in one step. Because it is compatible with BMEXBP Ethernet plus X-bus racks, you often keep the existing chassis and wiring.
Packaging line retrofit. Port mirroring helps engineers capture traffic for troubleshooting without disrupting the live network. The embedded switch means fewer cables, fewer failure points, and a cleaner panel.
Installation and Setup Notes
Mount the module in a compatible BMEXBP rack and confirm the rack supplies internal power. Use shielded twisted pair cable on all three RJ45 ports to protect signal integrity in electrically noisy cabinets. Keep the ambient air temperature between 32 and 140 °F (0 to 60 °C). The enclosure carries an IP20 rating, so install it inside a control cabinet rather than on an open panel. After power-up, check the RUN and ERR LEDs first, then verify ETH MS and Eth NS before you configure web services.
Maintenance and Reliability
Inspect the module periodically for loose connectors, dust buildup, and cabinet overheating. The unit has no moving parts, so wear is minimal. The main risks are environmental: heat, moisture, and vibration. Keep the cabinet filter clean and confirm the 0 to 60 °C range is respected. If a port LED stays dark, test the cable and the partner device before replacing the module. A spare BMENOC0311 on the shelf shortens unplanned downtime considerably.
Compatibility and Integration
The module works inside Modicon M580 racks and communicates over Ethernet backplane. It supports Modbus TCP and Ethernet/IP for I/O scanning and messaging, plus SNMP for network administration. RSTP support allows ring topologies with managed switches. FactoryCast configurable web services give you browser-based diagnostics. Confirm your controller firmware and rack type before ordering, because product version affects current consumption.
What to Verify Before You Buy
Check four things: the rack type (BMEXBP Ethernet plus X-bus), the module product version, the network protocol your devices use, and the cabinet temperature range. The module ships as one unit per package and is returnable. It carries CE marking under the 2014/35/EU low voltage directive and the 2014/30/EU electromagnetic compatibility directive. Country of origin is France. SpareTechPLC stocks industrial automation parts and can confirm availability and lifecycle status for your specific revision.
