Hi Everyone,

I am building a project using a TP177 micro and a S7-200(221) Plc.using WinCCflex 2008 i am setting up external tags to monitor outputs and to set bits in the PLc. When i press the button on the screen no output are set it does not seem to be communicating.They are connected with a profibus cable and i have set the connnection in wincc to DP.

Am i over looking somethimg simple?

Thanks
