So the boss flew to Germany for exhibition and set up our system for use in a demo. Turns out the Profinet feature we haven't tested doesn't work. So they have secrets connections to the switches so the lights blink and it looks like it's working.
He is bringing me a Profinet device home so we can fix it and test it before we have a customer try and buy it.
Profiles devices don't care about IP Adresses, Just Profinet device Names.
