Opc Data Type Is Empty - Cannot Read?


Recommended Posts

Hello,

I have a development trying to pinpoint why does the DAQFactory not read the data from my OPC server,

 

When i click "Properties" in the "OPC Item Browser" it appears that all the tag properties - including the value - are read in correctly. HOWEVER, the data type of the *value* of the tag is being incorrectly read as "VT_EMPTY" instead of "VT_Double". This tag is correctly read by the OPCQuickClient - as indicated in the attached screenshot.

 

Please help,
