Schneider BMXNOC0401 | Modicon M340 Ethernet Module

The Schneider BMXNOC0401 brings high-speed Ethernet connectivity to the Modicon M340 platform. This module supports a 10/100 Mbit/s transmission rate for reliable data exchange. It uses a standard RJ45 interface for straightforward cabling. The unit draws only 190 mA from the 5 V DC rack power supply. Weighing just 0.21 kg, the Schneider BMXNOC0401 fits perfectly into any M340 rack slot.

Communication Protocols and Network Capabilities

The Schneider BMXNOC0401 supports both Modbus TCP and Modbus UDP protocols. Therefore, it connects seamlessly to drives, HMIs, and SCADA systems. This module handles up to 16 simultaneous connections for small to medium networks. It also offers embedded web server functionality for remote diagnostics. Consequently, you can monitor system status without leaving your desk.

Diagnostics and Connectivity Features

Two LED indicators simplify on-site troubleshooting for the Schneider BMXNOC0401. These LEDs show Ethernet activity (ETH) and module status (RUN/ERR). Moreover, this module supports automatic IP configuration via DHCP. You can also set a fixed IP address for stable network operation. Thus, the Schneider BMXNOC0401 reduces installation time and minimizes configuration errors.
