Product Introduction
The Schneider BMENOC0301 is a network communication module from the Modicon M580 series, designed for process and control communication in Ethernet IP and Modbus TCP environments. This module integrates an embedded multiport switch and supports advanced network services such as bandwidth management, FDR server, SNMP, and RSTP for robust failover and redundancy. It is ideal for applications requiring high availability and minimal network downtime, as it actively prevents single points of failure through its redundant protocol support.

Industry Applications
The BMENOC0301 is commonly deployed in process control systems where network reliability is critical. In a water treatment plant, for example, the module ensures uninterrupted communication between redundant CPUs and remote I/O racks. Its RSTP support automatically reconfigures the network topology in case of a link failure, preventing data loss. Another application is in manufacturing assembly lines, where the embedded web server enables quick diagnostics and maintenance, reducing mean time to repair.
Installation & Mounting
Install the Schneider BMENOC0301 into the Ethernet + X-bus slot of a Modicon X80 rack with an Ethernet backplane (BMEXBP…). The module occupies one slot and can co-exist with up to four similar modules per rack. Ensure the rack supplies the required 3.3 V DC current (900 mA for version >=13, 1800 mA for older versions). Use shielded twisted-pair RJ45 cables for Ethernet connections. No additional external power supply is needed.
Compatibility & Integration
This module is compatible with Modicon M580 standalone CPUs (BMEP58…), redundant CPUs (BMEH58…), safety CPUs (BMEP582…), and safety redundant CPUs (BMEH582…). It also integrates with Modicon X80 racks via the Ethernet backplane. The BMENOC0301 supports both Modbus TCP and Ethernet/IP protocols, making it suitable for mixed-protocol environments. For seamless integration, ensure firmware version compatibility and configure network settings via the embedded web server.
Purchasing Advice
When ordering the Schneider BMENOC0301, verify the product version to ensure correct current consumption specifications. The module is returnable and comes in a single-unit package (PCE). For bulk needs, consider the S02 packaging which contains 15 units. UBEST Automation (ubest101) offers genuine spares with fast shipping. Always check compatibility with your existing rack and CPU before purchase.
