Wago 750-362 FC Modbus TCP

Why Choose the WAGO 750-362 Modbus TCP Fieldbus Coupler?

The WAGO 750-362 is a Modbus TCP/UDP fieldbus coupler designed to connect the modular WAGO I/O System 750/753 to industrial Ethernet networks. It acts as the communication interface between distributed field devices and PLC or SCADA systems, enabling reliable data exchange between connected I/O modules and Modbus-based automation controllers.

During system start-up, the coupler automatically detects all connected digital, analogue and specialty I/O modules and creates a local process image. This process image maps all signals from the I/O modules and transfers them through the Modbus TCP/UDP interface for communication with automation systems. :contentReference

The device features dual RJ-45 Ethernet interfaces with an integrated switch, allowing simple line topology wiring without the need for additional network switches or hubs. This makes the coupler ideal for distributed industrial automation systems and modern Ethernet-based control architectures. :contentReference
