The first time i did it, it worked, i was able to monitor from  OPC Scout V10 all my tags.

Then from the moment i disconnect and and try again to connect, it didn't work again. The result of the variables are "Bad_waiting"

I tried again the same procedure from the beginning with no result.

 i work in virtual machine, so i install from the beginning the simatic net V12 and follow the PDF, but never works.

Please help me if you know something about this 

Hello isaakkis

do you have changed something?? like Firmwareupgrade of the PLC or reloading the PC Station?

-> Do you have tried to restart the PLC?

-> Which Versions of Simatic Net and TIA Portal and PLC Firmware Version do you use exactly?
