PI Interface for OPC DA is not reading correct data

Hi all!


I am trying to collect some bool data from an OPC Server with PI Interface for OPC DA.

Although some of the points are TRUE on the server and the PI OPC Client is correctly reading TRUE, the interface is reading FALSE.



I am using Location2 = 2, as the source point is type vt_bool, but have already tested Location2 = 0 as well.


There are also some "TRUE" values in the past, so the collection has eventually worked.


What am I missing here?
