I have a question about creation a data unit type like below:
Data types:
TYPE DIn :
STRUCT
In:INT;
Flag:INT;
END_STRUCT
END_TYPE
If I declare a GlobalVariable like below:
VAR_GLOBAL
I:DIn;
END_VAR
when in a POU I insert a BOOL derivate from this G.variable (i.e. I.Flag.0 or I.In.1 and so)
the comment that I assign to the bit doesn't be automatically assigned every time
the same bit is used.
The same issue happens with Dt composed by ARRAY of Bool.

Thanks for your co operation
