we are using opc da communication.
opc da client is running on wincc oa.
I want to know bad connection information.
if some tag is deleted on opc da server, I have to make a alarm on wincc oa.

How do I know the tag connection is bad ?

Please have a look at the WinCC OA Documentation and search for the config entry "mapInvalidAdressToDrvInvalidBit".
