Hello,

maybe strange is that PB address 0 which can be set generally to PC station (Programming NTB with MPI/DP port f.ex.). Can you simply tell us other devices addresses on your network? What address has Panel set? Check internal settings on panel and also WinCC prj for sure, both need to be identical but not set to 0, which is used for Diagnostic/Programming station. Hope you also don't have conflict with same existing addresses on more devices...
