Technical Specifications Overview

Functional Overview and Network Connectivity

This communication module provides high-speed Ethernet connectivity for Modicon Quantum systems. It enables seamless data exchange with plant networks and enterprise systems. The 140NOL91100C supports multiple industrial protocols for broad device compatibility. Moreover, the module handles both Modbus TCP and EtherNet/IP communications simultaneously. This dual capability simplifies integration in mixed-vendor automation environments. The integrated web server allows configuration and diagnostics through any standard browser. Consequently, engineers gain quick access to network status and module health.

Protocol Support and Data Exchange Capabilities

The Schneider 140NOL91100C supports Modbus TCP for connectivity with drives, instruments, and HMIs. It also supports EtherNet/IP for seamless integration with Rockwell-based systems. The module handles the Schneider UNI-TE protocol for native system communication. Furthermore, it supports Modbus UDP for high-speed broadcast applications. The module maintains up to 128 simultaneous TCP/IP connections for large distributed systems. This capacity accommodates multiple clients accessing data simultaneously. The module also acts as an SNMP agent for network management integration.

Web Server and Remote Diagnostics

The integrated HTTP server provides a user-friendly web interface for module configuration. Users can view network parameters, connection status, and diagnostic counters through the browser. The web interface also displays firmware versions and manufacturing data. Additionally, it provides ping and network troubleshooting tools. The 140NOL91100C supports remote firmware updates via TFTP over Ethernet. This remote update capability simplifies maintenance without physical access to the module. The web server also logs access attempts and configuration changes for security auditing.

Network Services and Addressing Configuration

The module includes DHCP client for automatic IP address assignment. It also supports DNS for hostname resolution on plant networks. Static IP configuration remains available for fixed addressing requirements. The module supports both IP v4 and IP v6 addressing schemes. Additionally, it provides QoS (Quality of Service) for traffic prioritization. The 140NOL91100C includes network address translation capabilities for security segregation. These features ensure flexible deployment in complex network architectures.

Physical Architecture and Installation Details

The module measures 65 mm x 130 mm x 140 mm (2.6″ x 5.1″ x 5.5″) and weighs approximately 0.60 kg. Its standard Quantum form factor fits all compatible racks. The front panel provides a shielded RJ45 connector with integrated status LEDs. These LEDs show network speed, link status, and data activity. The backplane connector interfaces with the Quantum system bus for data exchange. The module mounts securely in the Quantum chassis using the standard retention mechanism.

Power Supply and Energy Storage Features

The module draws 350 mA from the 5 VDC system bus. This moderate consumption suits typical Quantum rack configurations. The internal 100 µF capacitor provides ride-through during brief power interruptions. This capacitance maintains module operation for up to 10 ms during outages. The module also includes brownout detection for orderly shutdown on extended power loss.

Diagnostic Capabilities and Status Indication

Four front-panel LEDs provide clear operational feedback for maintenance personnel. A green Power LED confirms correct supply voltage. A Run LED indicates normal module operation. An Error LED alerts users to configuration or hardware faults. A Link/Activity LED shows network connectivity and traffic. The module also logs network errors, timeout events, and connection statistics. Through the web interface, engineers can view detailed diagnostic information. The SNMP interface enables remote monitoring from network management stations.

Environmental Conditions and Certifications

The module operates reliably from 0°C to +55°C ambient temperature. Storage temperatures range from -40°C to +85°C. The unit carries CE, UL, and CSA certifications for global deployment. Install the module in a clean, dry control cabinet. The module also complies with IEEE 802.3 Ethernet standards. This compliance ensures interoperability with standard network equipment.
