Vijeo Designer is linking to the Unity Pro tag database but some on the boolean tags in the DDT are not showing up. Why?

Issue:
Vijeo Designer is linking to the Unity Pro tag database but some on the boolean tags in the DDT are not showing up.  Why?

Product Line:
Vijeo Designer, linked variables, Unity Pro, bit rank

Environment:


Cause:


Resolution:
If the boolean tags from the DDT in Unity Pro has blue arrows, that means that it is a bit extraction of the byte or word (bit rank).  Those bit extractions alias are not supported in Vijeo Designer.  Work around would be to move these booleans to a memory bit address in the PLC.
