I sent the wrong files but I found my problems. In DEVNET file i had written MAC_ID but the right is MacID.
Two important questions is if I can not have the PLC as master and slave on the same network?
if KRC2 is master in this network, later I'll have another KRC2 controller, so, i will be two KRC2 on the same network, the question is, will have two MASTER KRC2 in the same network?
