Raspi as LowCost PLC with industrial HW (lemm.ee)

Studying mechatronics engineering I am very interested in trying to use my spare RPi that I have lying around as a PLC to get better at programming.

Since I don’t have the money to buy an industrial Controller I thought this would be a great fit. I still want to have a touch of industrial flair and I am looking into connecting a Beckhoff ethercat coupler like the EK1100 or the BK1120 to the Raspberry.

Has anyone testde this out? The question mainly is, if the raspi can function as an Ethercat master?

(Yes i run the codesys Raspi Runtime on the Pi :) )

You can also use your computer as a beckhoff PLC to connect to the couplers

Yes that is also a possibility. However i’m trying to set up a system that’ll run independent if my computer is on or not.
