I am attempting to write data from a deltaV tag, with a good quality string to an empty tag using a pipe. I can see the empty tag in Matrikon OPC explorer with Quality "Good, non-specific", and I can set up the pipe and validate it, with both points being good, however, the value of the deltaV tag isn't written over to the blank point. Any idea why this is?
Canonical type of deltaV tag is VT-BSTR, and empty tag is VT_EMPTY.
