The Schneider Electric Modicon Quantum 140NOC78100 Ethernet Network Interface Module (NOM) is an essential communication component designed for the robust Quantum PLC platform. It provides a integrated and high-performance interface to connect the control system to modern Ethernet networks, facilitating data integration, remote access, and enhanced diagnostics.

This module installs directly into the Quantum PLC rack, operating as a dedicated network co-processor. This architecture offloads network communication tasks from the main CPU, ensuring deterministic PLC scan times are not impacted by network traffic, which is crucial for real-time control performance.

Key Features & Benefits:

• High-Speed Connectivity: Features a single RJ45 port supporting 10BASE-T and 100BASE-TX Ethernet standards with auto-negotiation and auto-MDIX for simple and flexible network integration.

• Standard Protocol Support: Communicates using standard TCP/IP and UDP/IP protocols, enabling connectivity with a wide range of devices, including HMIs, SCADA systems, other PLCs, and enterprise-level systems for data collection.

• Unity Pro Integration: Fully configured and managed within the Schneider Electric Unity Pro or Control Expert software suite, providing a seamless engineering experience for programming, diagnostics, and network variable mapping.

• Enhanced Diagnostics: Includes extensive LED status indicators for power, network activity, link status, and connection health, enabling rapid troubleshooting of network issues.

• Rugged Industrial Design: Built to operate reliably in harsh industrial environments with extended temperature ranges, immunity to electrical noise, and vibration resistance.

• Data Gateway: Acts as a bridge between the Quantum backplane and the plant network, allowing for efficient peer-to-peer communication between PLCs and data access for supervisory systems.

Typical Applications:

• Connecting Modicon Quantum PLCs to plant-wide Ethernet networks for data acquisition.

• Enabling remote programming and monitoring (upload/download, diagnostics) from engineering stations.

• Facilitating communication between multiple PLCs on a control network (e.g., interlocking).

• Integrating process data into HMIs, SCADA systems, and manufacturing execution systems (MES).

• Water/Wastewater treatment, Oil & Gas, Power Generation, and other critical infrastructure applications.

The 140NOC78100 module is a foundational element for building connected, modern industrial control systems, ensuring reliable and secure data flow from the factory floor to the top floor.
