How to install EtherLab EtherCAT master on Ubuntu 24.04

This short instruction shows you how to install the EtherLab EtherCAT master, also known as the IgH EtherCAT Master.

Add the repository:

install_etherlab_ethercat.sh
curl -fsSL https://download.opensuse.org/repositories/science:/EtherLab/Debian_12/Release.key | gpg --dearmor | sudo tee "/usr/share/keyrings/etherlab.gpg" >/dev/null
sudo echo "deb [signed-by=/usr/share/keyrings/etherlab.gpg] https://download.opensuse.org/repositories/science:/EtherLab/xUbuntu_24.04/ ./" | sudo tee /etc/apt/sources.list.d/etherlab.list
sudo apt update

Now install the EtherCAT master from the repository we just installed

install_ethercat_master.sh
sudo apt install ethercat-master

In case you also need the development headers, install them using

install_libethercat_dev.sh
sudo apt install libethercat-dev

For more info, see the EtherLab page

How to configure the EtherCAT Master

Now open /etc/ethercat.conf and set MASTER0_DEVICE to the name of your network interface.

This typically cannot be the same network interface you’re using for internet or other purposes. You can find the name of your network interfaces using ifconfig.

ethercat_conf_setting.sh
MASTER0_DEVICE="enx00e04c680004"

Now you can (re)start the EtherCAT master using

restart_ethercat.sh
sudo systemctl restart ethercat
