jerzydziewierz Posted August 26, 2015 Share Posted August 26, 2015 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, Dr Jerzy Dziewierz Link to comment Share on other sites More sharing options...
jerzydziewierz Posted August 27, 2015 Author Share Posted August 27, 2015 OK, after debugging the OPC server, i figure out that this is an issue with the OPC server having a problem. I have reported this to Kepware. In the meantime, i got another problem . . . . started another thread . . . . Link to comment Share on other sites More sharing options...
