ac_ing Posts: 3 Rating: (0)	Hi, I need help for the configuration of a CP341 PtP with dognle RTU Slave. I have to add this device in an existing PLC system. I don't understand if I have to load the driver before mounting the card on the rack or if I have to mount it and then load the driver (with hardware configuration). Please someone can send me more informations or the sequence of steps. Sorry for my english.
