Well i'm in a war of protocols it seams :slight_smile: Device X wont talk to device Y where X is Linux ubuntu and Y is a Siemens s7-1200. Now it seams rather complex but as this is "THE" forum for people who create microcontroller stuff.. and turn around every byte we see. I was thinking maybe..…

Might an arduino-ethernet be able to talk with a S7-1200 plc with profinet
