Hi! What do you mean "S7 Siemens plc GSDML isn’t easy to find". The GSDML file is generated directly by the TIA PORTAL programming software.
Unfortunately I can't program the master PLC because is not installed by me. My PLC as IO Device was intended to be used like any other io Device but for some reason it doesn't work. Anyway I've already sent the .xml file to KUKA service. I do not think care much about it but we'll see. I'll solve my problem in another way... thanks.
