Introduction

The WAGO I/O System 750 is distinguished by its more than 500 different modules for the field-side connection of sensors, actuators and communication devices and its openness to a wide range of fieldbus systems. This flexibility makes the WAGO I/O System 750 extremely attractive for many and very different fields of application.

This instruction shows how the WAGO I/O System 750 can be connected to the ctrlX CORE via EtherCAT.

Prerequisites

This instruction has been created based on 

  • ctrlX CORE V1.10
  • ctrlX CORE EtherCAT Master App V1.10
  • ctrlX PLC Engineering V1.10
  • ctrlX I/O Engineering V1.10
  • WAGO_750-0354_22.xml

and exemplarily with the following modules from the WAGO I/O System 750:

  • 750-354             Fieldbus Coupler EtherCAT
  • 750-430             8-channel digital input; 24 VDC; 3 ms
  • 750-530             8-channel digital output; 24 VDC; 0.5A
  • 750-559             4-channel analog output; 0..10 VDC
  • 750-468             4-channel analog input; 0..10 VDC; Single-ended
  • 750-600             End module
