Why Choose the WAGO 750-337 CANopen Fieldbus Coupler?
The WAGO 750-337 is a CANopen fieldbus coupler designed to integrate the modular WAGO I/O System 750/753 into CANopen automation networks. Acting as the communication gateway between distributed field devices and the automation controller, the coupler exchanges process data between connected I/O modules and the CANopen master system.
The coupler automatically detects installed digital, analogue and speciality I/O modules and builds a local process image representing the entire I/O configuration. Digital signals are transmitted bit-by-bit, while analogue signals and specialty module data are transmitted as bytes or words, enabling efficient communication across industrial automation systems. :contentReference
Designed for scalable distributed control architectures, the 750-337 can support up to 64 connected I/O modules per node and communicates with the master controller using standard CANopen process data objects (PDOs) and service data objects (SDOs). :contentReference

Industrial Automation Fieldbus Communication
Fieldbus couplers act as the communication bridge between distributed I/O modules and automation controllers. The WAGO 750-337 enables sensors, actuators and monitoring devices connected to WAGO I/O modules to communicate with PLCs or industrial PCs over the CANopen industrial network.
Within the WAGO I/O System architecture, the coupler automatically maps signals from connected modules into the CANopen process data structure. Digital signals are grouped into bytes while analogue signals are transmitted as words, allowing efficient communication between the field level and the control system. :contentReference
