In this tutorial, you will learn how to set up a Raspberry Pi with Codesys to act as both a PLC and an EtherCAT master. It will be used to control the on-board LED found on the EtherCAT Arduino Shield by Esmacat (EASE) Slave device that is attached to an Arduino Uno.
-
First, some general information about Raspberry Pi and Codesys is discussed.
-
After learning to set up the Pi and Codesys, you will learn to implement a practical project to blink the onboard led on EASE based on user input by updating EASE registers using Codesys.
