5.1.4
Execution order and feedback loops
It is possible to draw multi-layer configuration logic that contains feedback loops with
the Application Configuration tool. The execution order of logic functions is
calculated automatically in the Application Configuration tool, but the execution
order can also be set manually. If the automatically calculated value causes the
function to be executed one task cycle time after the other logic functions in the same
loop, the execution order number can be set manually to prevent delays, for example,
in output activation.
To perceive accurate time stamps from binary input signals to
function blocks, direct logic connection should be used in the
Application Configuration tool. Due to internal execution order, time
stamps may not be accurate if additional logic is used to connect
priority signals to function blocks.
