they are both Any_BIT type, why monitoring the input data of F_OR
the value True or flase is not displayed, but with ND(Any)

Because ANY_BIT is not a specific type and could be anything from BOOL to LWORD.

You could theoretically write some code, which calculates the output type, based on the input types for the IDE, automatically typing the output if possible.
