I am also interested in extracting bits from a PI Point. We have an alarm status word read from HIMA and each bit in the word denotes a particular alarm state. Rather than use up thousands of tags reading the data into separate tags, I wanted to use AF to do a bitwise AND of the relevant bit into an AF Attribute which can then be displayed in any PI Client.
However it sounds like this is not possible at the moment and I have to try and do this using SQL. This is a real pain!
I think that ProcessBook data sets will also not work because of the limitations of the PE functions available?
This question was branched from PI-AF attribute pointing to a Blob bit .
This is a different question and should benefit from being on its own thread.
