What Is the BMXNOC0401?
When network congestion disrupts production, the BMXNOC0401 provides reliable connectivity. This Schneider Modicon M340 Ethernet TCP/IP network module integrates seamlessly into automation systems. It supports both EtherNet/IP and Modbus/TCP protocols, making it a versatile choice for industrial networks.
Technical Specifications Breakdown
The BMXNOC0401 features an embedded 4-port switch with four RJ45 Ethernet ports operating at 10/100 Mbit/s. It consumes 555 mA at 3.3 V DC via internal power supply from the rack. The module includes five diagnostic LEDs: one green for RUN, one red for ERR, one amber for ETH STS, and two green/red for MS and NS status. Operating temperature ranges from 32 to 140 °F (0 to 60 °C), with relative humidity from 10 to 95% without condensation. It carries IP20 protection and multiple certifications including CE, UL, CSA, RCM, EAC, Merchant Navy, ATEX zone 2/22, and IECEx zone 2/22.
Industry Applications
In manufacturing plants, the BMXNOC0401 connects PLCs to supervisory systems using Modbus TCP I/O Scanner and Messaging. For logistics warehouses, it enables real-time data exchange via EtherNet/IP I/O Scanner and Messaging. Its support for RSTP and port mirroring ensures network redundancy and diagnostics, minimizing downtime in critical processes.
Installation & Setup Guidance
Mount the BMXNOC0401 in a standard Modicon M340 rack. Connect up to four devices using standard Ethernet RJ45 cables. Configure the module via the integrated web server or Data Editor. The module supports bandwidth management and FDR server for automatic device replacement. Ensure proper grounding and follow the rack's internal power supply specifications.
Maintenance & Reliability
Regularly inspect the LED indicators for RUN, ERR, and network status. Verify that ambient temperature stays within 32 to 140 °F. Keep the module free from dust to maintain IP20 protection. The BMXNOC0401 is designed for long service life in industrial environments, reducing total cost of ownership.
Compatibility & Integration
The BMXNOC0401 integrates with Modicon M340 automation platforms. It supports Transparent Ready class B30 and communicates via Ethernet RJ45 at 10/100 Mbit/s. Compatible with Modbus TCP and EtherNet/IP networks, it works with Schneider Electric and third-party devices. The module also supports SNMP network administration and Rack Viewer for easy diagnostics.
Selection Guide & Purchasing Advice
Before ordering, verify that your system uses a Modicon M340 rack with internal power supply. The BMXNOC0401 is a standard format module weighing 0.2 kg. SpareTechPLC stocks this module and offers fast shipping. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Troubleshooting & Common Issues
If the ERR LED is red, check the rack power supply and module seating. A steady amber ETH STS LED indicates network activity; no light suggests a cable fault. For NS LED issues, verify IP address configuration and network cable integrity. Use port mirroring to diagnose traffic problems without disrupting operations.
