Don't forget to set active connection estabilishment at S7-300 side ! I never get it working by passive estabilishment at S7-300 side. At S7-1200 side you just configure connection to unspecified partner and use TCP protocol. S7-1200 side is the same program as from example here, but just take one PLC and change partner to unspecified. The Problem with CP343-1 Lean, at S7-300 side it can't be reached ?? Also in S7-1200 side when i configure connection to unspecified partner,it can't be reached Iam using Step-7 TIA Portal V13 i have uploaded Screen shots of my problem Attachment Communication.zip (1087 Downloads)
