Wago 750-375 FC Profinet, G3

Why Choose the WAGO 750-375 PROFINET IO Fieldbus Coupler?

The WAGO 750-375 is an advanced PROFINET IO fieldbus coupler designed to integrate the modular WAGO I/O System 750/753 into industrial Ethernet automation networks. It enables reliable real-time communication between distributed field devices and PLC controllers using the widely adopted PROFINET industrial networking standard. :contentReference

During start-up the coupler automatically detects all connected digital, analogue and speciality I/O modules and creates a local process image. This image allows controllers to access field signals efficiently while maintaining deterministic communication across the network. :contentReference

The device includes an integrated two-port Ethernet switch, allowing network wiring in a line topology without additional switches or hubs. This simplifies installation and reduces infrastructure requirements in distributed automation systems. :contentReference

PROFINET Industrial Network Integration

PROFINET is widely used in industrial automation systems to connect PLC controllers, distributed I/O modules and industrial devices over Ethernet infrastructure. The WAGO 750-375 enables field-level sensors and actuators connected to WAGO I/O modules to communicate with controllers through the PROFINET protocol, allowing scalable distributed automation architectures. :contentReference

Within the WAGO I/O architecture, signals from connected modules are automatically mapped into the Ethernet process image and transmitted across the network. Digital signals are transferred bit-by-bit while analogue values are transmitted word-by-word, ensuring efficient communication with PLC systems. :contentReference

Typical Applications

• Distributed PLC I/O systems using PROFINET networks.
• Industrial machine automation.
• Factory automation and production lines.
