Wago 750-842 Controller Ethernet, G1

Why Choose the WAGO 750-842 Ethernet Controller?

The WAGO 750-842 is a compact Ethernet programmable controller designed for decentralised industrial automation using the modular WAGO I/O System 750. This DIN-rail PLC combines control functionality, I/O interfacing and Ethernet communication in a single device, enabling efficient implementation of distributed automation architectures. :contentReference

The controller communicates via Ethernet TCP/IP and supports protocols such as Modbus TCP, Modbus UDP and HTTP. By executing PLC logic locally while communicating with higher-level systems, the controller allows complex industrial processes to be divided into modular, independently testable control functions. :contentReference

Using IEC 61131-3 programming standards and the WAGO-I/O-PRO engineering environment, automation engineers can develop flexible control programs to manage sensors, actuators and distributed I/O modules connected to the WAGO 750 Series platform. :contentReference
