Example shows a simple situation where the execution order causes one cycle time
delay if the NOT port is executed in the order determined by the automatic calculation.

orders
By setting a smaller execution number than in the AND port to where the NOT port
is connected, it is possible to fix the execution order of all functions in a loop so that
they are handled in the same task.

port
Execution number can be changed by right-clicking the function and selecting
Change CycleTime ExecOrder.
After manually defining the execution number, the function is no longer part of the
automatic execution order calculation. The function can be included back to the
automatic calculation by right-clicking the function and selecting Include FB in
calculation.
