Ethercat Motion asics

Hello Experts,

Is there any readymade package with LinuxOS+RTKernel+Ethercat Master prebuilt.?

Can someone please explain the core concept of Ethercat communication compared to traditional step and dir method?

I was wondering what parameters vary from machine to machine in terms of Ethercat configuration?

For example, I have seen that the Ethercat module needs the network card ID when installing/configuring Ethercat Master.
