Network Connectivity Features

The Schneider 140NOE77110C provides auto-sensing 10/100 Mbps Ethernet connectivity. It negotiates speed and duplex settings automatically with any network switch. This module supports up to 128 simultaneous Modbus TCP sessions without performance loss. You can connect multiple HMIs, SCADA servers, and other PLCs simultaneously.

Protocol Support and Data Exchange

This module handles a wide range of industrial protocols on a single port. It supports Modbus TCP for controller-to-controller and controller-to-HMI communications. Moreover, the unit acts as an FTP server for file transfers and data logging. You can also send email alarms directly from the module using SMTP.

Web Server and Diagnostics

A built-in web server provides real-time module status and advanced diagnostics. You can access configuration pages using any standard web browser. The server displays connection tables, error counters, and network statistics. Consequently, technicians can troubleshoot issues without any proprietary software tools.

Addressing and Configuration

You can assign an IP address using static configuration or dynamic methods. The module supports BOOTP and DHCP for automatic address assignment from a server. A serial debug port (DB9) allows local configuration during initial setup. For best results, use static addressing for critical control networks.

Installation and Compatibility

Mount this module in any slot of a Quantum 140 series rack. The unit draws 650 mA from the +5 VDC backplane supply. It works with all Quantum CPUs running firmware version 2.5 or higher. You need Unity Pro XL software for full configuration and programming access.

Diagnostic Indication

Six LEDs on the front panel provide immediate network and module status. A green Link LED shows an active physical connection at 100 Mbps. The Activity LED flashes when data packets transmit or receive on the network. A Fault LED illuminates for IP conflicts, duplicate MAC addresses, or internal hardware errors.

Energy Storage and Reliability

A 220 µF capacitor retains configuration data during momentary power interruptions. The module stores its firmware and all settings in non-volatile flash memory. You can replace the unit without reloading the IP configuration or web pages. Therefore, this design minimizes downtime during emergency replacements.

Why Choose This Module

This enhanced Ethernet module offers double the connection capacity of standard units. Its 128-session limit supports large SCADA systems with many clients. Therefore, manufacturers choose this module for complex production lines and plant-wide monitoring.
