function that also propagates timestamp and quality of input signals
The execution of different function blocks within the same cycle is determined by the order of
their serial execution numbers. Always remember this when connecting two or more logical
function blocks in series.
Always be careful when connecting function blocks with a fast cycle time to
function blocks with a slow cycle time.
Remember to design the logic circuits carefully and always check the execution
sequence for different functions. In other cases, additional time delays must be
introduced into the logic schemes to prevent errors, for example, race between
functions.
