The Original New Schneider Electric BMXNOC0401 is a 4-port Ethernet TCP/IP network module for the Modicon M340 automation platform, designed to provide high-performance industrial network connectivity for programmable automation controllers (PACs). It supports simultaneous EtherNet/IP and Modbus TCP protocols, with an embedded 4-port switch for flexible network topologies including ring configurations via RSTP (Rapid Spanning Tree Protocol). Part of the Modicon M340 range, this Transparent Ready Class B30 module is suitable for process industries, renewable energies, water, cement, manufacturing, infrastructure, and machine automation applications.
