The 414-3DP is new on the network, but i can see the other PLC's so i know the link is up. When i enable the comms i get an error 1 from the SFB's. i have used the logic from another PLc so the logic is good!!. Has any one any idea why there is no comm's, is there something that has to be done with a new plc on the network. Hope you can help Cheers Steve

Connections which are correctly set up have a green arrow in the connection table of the concerned CPU. This is the first step, even before looking to the status of the sfb in your program.
