Figure 185: Example designation, serial execution number and cycle time for logic
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 dif
ferent functions. In other cases, additional
time delays must be introduced into the logic schemes to prevent errors,
for example, race between functions.
