Hiya Guys,
Easy one for ya....got a SIemens SIMATIC PC with profibus card, WinCC6.1 SCADA system communicating to a Siemens S&-315-2DP on profibus.
S7-315 = Node 2 - Profibus
SCADA = Node 4
This system was working before but now i've come back to finish the project it doesnt seem to communicate.
I have a couple of tags on the SCADA that are just flashing from a greyed out color to white and the value stays at zero. When i disconnect the profibus it stays greyed out....so it is sort of communicating but i cant see the problem. The plc doesnt report any problems and the scada package doesnt either.
Is it my tag setup??????
Cheers one confused welsh man
