getBit expression issues

I am having issues with the getBit() expression working in V8.0.16 . I developed my app in 8.1.10 and had to import into an 8.0.16 project. Expression worked in 8.1 but does not work in 8.0. Is there a know issue?

Nothing I’m aware of. How are you using it and what’s not working?

Its an OPC tag, a DINT read from plc , then individual bits tested. Only way to get it to work to to specify .Value of the tag in the expression. In 8.1, the entire OPC was read and it worked.
