Why Choose the WAGO 750-338 CANopen Fieldbus Coupler?
The WAGO 750-338 is a CANopen fieldbus coupler with D-Sub connection designed to integrate the modular WAGO I/O System 750/753 into CANopen automation networks. Acting as the communication interface between distributed field devices and PLC or industrial controllers, the coupler exchanges process data between connected I/O modules and the CANopen master system. :contentReference
During start-up the coupler automatically detects all connected I/O modules and creates a local process image representing the inputs and outputs of the installed system. Digital signals are transmitted bit-by-bit while analogue and specialty module data are transmitted as words or bytes, enabling efficient communication across distributed industrial control architectures. :contentReference
Designed for scalable automation systems, the coupler supports up to 64 connected I/O modules per node and communicates with the controller using CANopen process data objects (PDOs) and service data objects (SDOs), providing reliable data exchange between sensors, actuators and automation equipment. :contentReference

Industrial Automation Fieldbus Communication
Fieldbus couplers provide the communication bridge between distributed I/O modules and central automation controllers. The WAGO 750-338 enables sensors, actuators and monitoring devices connected to WAGO I/O modules to communicate with PLCs or industrial PCs over CANopen industrial networks. :contentReference
Within the WAGO I/O System architecture, the coupler automatically maps signals from connected modules into CANopen PDO structures. Digital signals are grouped into bytes while analogue values are transmitted as words, ensuring efficient process data exchange between field devices and the automation controller. :contentReference
Typical Applications
- Distributed PLC I/O systems using CANopen networks.
- Industrial machine automation.
- Factory automation and production equipment.
- Process monitoring and control systems.
