Hi JPG, I've got PLC V350 and URB-TCP - 2pcs. URB-TCP- I connected to 0 and 2 socket of V350. But If I load programm for 1st URB, after 2nd URB, then 1st is disconnect. If I load 2nd URB, after 1st URB, then 2nd is disconnect. Could you give me example, please, how you made it? I think that I've got issue with settings of connection in ladder -
