Posting this as I can see there have been many discussions around accessing bit value's of DINT's.
I am using a Allen-Bradley CompactLogix L32E (v15 f/w) and Ignition 8 to build some an app. I have created dynamic UDT's to access the individual bits of any DINT tags. I noticed however, that if any of the DINT's in my PLC are configured as arrays (even if only 1 array) then I can access/browse the individual bits directly within ignition, no UDT or creation of separate tags required.
Just wondering if this is by design, bug or whatever may be the case.
This purely a browse phenomenon, and intentional. You can always use the bits of DINTs in OPC item paths by appending the dot and bit number to an integer type's item path. The array is confusing the browse operation to show these when it normally would not.
