I’ve worked with EtherCAT. Nerves uses Buildroot which includes an EtherCAT package igh-ethercat. It goes through the standard network stack. It also has a few hardware drivers such as e100 for better performance. To include it you need to make a custom Nerves system and add the package.
Ultimately, we found it didn’t have the performance we needed for our specific hardware. So we made a custom, private Nerves system that uses Acontis’s EtherCAT offering.
