I can no send any singal from OP to PLC. Can any body help me about this problem ? How i can resolve this problem?? Is it "Wincc flexible 2007 Runtime" problem or.. ?? How do you want to communicate? MPI or Profibus? Have you set up the right connection in WinCC flexible? Satish Shah My 2nd question is whenever i start my PLC then EXTF is always on in RED LED and BUSF is blinking in RED.. What does it mean ?? When BUSF is blinking, you have some trouble at profibus network. When EXTF led is on, there is some fault. Please check Diagnostic buffer for more information. Best regards, Wizard
