Wago 750-348 FC Canopen, Dsub Eco

Why Choose the WAGO 750-348 CANopen ECO Fieldbus Coupler?

The WAGO 750-348 is a CANopen ECO fieldbus coupler with D-Sub interface designed to integrate the modular WAGO I/O System 750/753 into CANopen automation networks. It serves as the communication gateway between distributed field devices and the control system, enabling reliable process data exchange between connected I/O modules and a CANopen master controller.

The ECO version is engineered for systems with a reduced process image width. It is ideal for applications primarily using digital signals or small amounts of analogue data while still maintaining the flexibility and scalability of the WAGO 750 modular I/O platform. :contentReference

During system start-up the coupler automatically detects all installed I/O modules and generates a local process image. Digital inputs and outputs are mapped byte-by-byte while analogue values are transmitted as words through CANopen process data objects (PDOs), enabling efficient communication with PLCs or industrial controllers. :contentReference

CANopen Distributed I/O Integration

Fieldbus couplers act as the communication bridge between distributed I/O modules and automation controllers. The WAGO 750-348 allows sensors, actuators and monitoring equipment connected to WAGO I/O modules to communicate with PLCs or industrial PCs via the CANopen network.

Within the WAGO I/O architecture, the coupler automatically builds a process image from connected modules and transmits it through CANopen PDOs and SDOs. Digital signals are grouped into bytes while analogue values are transmitted as words, ensuring efficient data exchange across distributed control systems. :contentReference
