Issue:
In which order are the function blocks scanned (or execution sequence) in a Unity Pro FBD section?

Product Line:
Programming software

Environment:
Unity Pro

Cause:

Resolution:
The blocks are scanned (or executed) in the following order:
From top left position to bottom right position, with top having priority over left, as shown below (case 1)



If blocks are linked together, the execution order will now follow the flow of the link (case 2)



You can also force the execution sequence by going in the properties of the function block (case 3)
