Network Architecture and Protocol Support

The 140NOE35100C includes a 10/100BASE-TX Ethernet port with auto-sensing. This port automatically negotiates the correct speed with network switches. The module supports Modbus TCP/IP for controller-to-controller communication. It also handles HTTP for web-based diagnostics and configuration. The Schneider 140NOE35100C maintains up to 64 simultaneous Modbus connections. A built-in FTP server allows easy file transfers to the module.

Web Server and Diagnostic Capabilities

This communication module features a built-in web server for remote access. You can view module status and I/O data using any standard browser. The web server displays diagnostic information without additional software. The 140NOE35100C also includes an SNMP agent for network management. It sends email alerts using SMTP for fault conditions. Five status LEDs provide immediate visual feedback about network activity.

Data Exchange and Communication Performance

The Schneider 140NOE35100C exchanges data at 10 or 100 Mbps speeds. It supports both client and server modes for Modbus TCP/IP. The module acts as a gateway between the Quantum backplane and Ethernet network. It transfers up to 2048 registers of data per transaction. The 140NOE35100C handles multiple simultaneous requests without slowing down. Its 64-connection capacity suits large distributed control systems.

Physical Dimensions and Installation Guidelines

The Schneider 140NOE35100C weighs 0.315 kilograms for lightweight mounting. Its height measures 123.9mm, width 40.1mm, and depth 144.1mm. Install this module in any Modicon Quantum rack slot. The module consumes 4.2 watts from the backplane power supply. It operates reliably from 0°C to +60°C ambient temperature. Use a shielded Ethernet cable (CAT5e or higher) for best performance.

Energy Storage and Configuration Retention

The 140NOE35100C uses a 220 µF capacitor for temporary energy storage. This capacitor retains network configuration during brief power interruptions. It holds IP address and communication settings for up to 5 seconds. The module stores permanent configuration in non-volatile flash memory. Hence, the Schneider 140NOE35100C requires no battery for data retention. You will never perform battery replacement on this communication module.
