Wago 750-346 FC Devicenet, Eco

Why Choose the WAGO 750-346 DeviceNet ECO Fieldbus Coupler?

The WAGO 750-346 is a DeviceNet ECO fieldbus coupler designed to connect the modular WAGO I/O System 750/753 to DeviceNet industrial networks. It acts as the communication interface between distributed field devices and the control system, exchanging process data between connected I/O modules and the DeviceNet master controller.

The ECO version is optimised for applications with a smaller process image and reduced data width, typically installations that rely mainly on digital I/O signals or only limited analogue data. This provides a cost-efficient communication solution while maintaining the full flexibility of the WAGO 750 modular I/O architecture. :contentReference

During system start-up the coupler automatically detects all installed digital, analogue and speciality modules and creates a local process image. The process data is transferred via the DeviceNet fieldbus to the PLC or control system for further processing, enabling reliable communication between sensors, actuators and automation equipment. :contentReference

DeviceNet Distributed I/O Integration

DeviceNet is widely used in industrial automation systems for communication between controllers and field devices. The WAGO 750-346 enables sensors, actuators and monitoring equipment connected to WAGO I/O modules to communicate with PLC systems through the DeviceNet network.

Within the WAGO I/O System architecture, digital signals are grouped into bytes while analogue values are transmitted as words in the process image. This efficient data mapping ensures reliable process communication across distributed control systems. :contentReference
