EtherCAT IO on CODESYS With a Raspberry Pi
EtherCAT is a popular industrial Ethernet technology for real-time automation control, offering high speed and reliability.
Using CODESYS on a Raspberry Pi to manage EtherCAT I/O is a cost-effective and scalable solution for industrial automation projects. In this guide, we'll walk you through the steps to set up EtherCAT I/O with CODESYS and a Raspberry Pi.
Conclusion
Setting up EtherCAT I/O on a Raspberry Pi with CODESYS opens up endless possibilities for industrial automation projects. The combination of affordable hardware and powerful software like CODESYS provides a robust platform for developing custom automation solutions.
With the steps outlined in this guide, you should be able to set up and test your EtherCAT network successfully.
Supplies
You can use this diagram as your roadmap for connecting the Raspberry Pi and EtherCAT module.
Install Raspberry Pi OS
Download Raspberry Pi Imager tool from the official Raspberry Pi website.
install the image to your microSD card using the tool Raspberry Pi Imager.
When running the Raspberry Pi Imager enter your WIFI credentials, under extra options.
Install CODESYS Development System on your development PC
Available at: CODESYS Store International
Deploy CODESYS runtime to your Raspberry PI
- Open CODESYS and go to Tools > Update Raspberry Pi (or Deploy Raspberry Pi in some newer versions).
- Scan for Device: Click Scan. Your Pi should appear if it's on the same network.
- Credentials: Enter your Pi's Linux username (default: pi) and password.
- Install: Select the desired runtime version (usually the latest) and click Install.
- Runtime Mode: You may be asked to choose between Single Core or Multicore. For Pi 3/4/5, choose Multicore.
Open the hello world project and download it to the target.
