PLCs, Power Supplies & Others

The Schneider Electric 140NOC78000 acts as the primary Ethernet gateway for distributed I/O within the Modicon Quantum platform. This module delivers high-speed, deterministic communication for remote racks using standard Ethernet infrastructure. Furthermore, its embedded web server provides direct access for real-time diagnostics and configuration management.

This unit supports major industrial Ethernet protocols, including Modbus TCP and EtherNet/IP, for broad system compatibility. It operates in a full-duplex mode to ensure simultaneous, bidirectional data flow without collisions. Consequently, network performance remains robust and reliable for demanding automation tasks.

Network Architecture and Redundancy

The 140NOC78000 enables the creation of highly available network topologies such as redundant rings and daisy-chain loops. It transmits data at a standard 10/100 Mbit/s rate, suitable for most control and monitoring traffic. Moreover, its integrated hot standby redundancy architecture guarantees continuous operation, which is critical for process integrity.

Handling a maximum of 128 concurrent connections, this module can support extensive distributed I/O systems. This high connection capacity allows for the integration of numerous devices and sub-systems onto a single network segment. Therefore, it simplifies network design and reduces overall complexity.
