2 Instruction Descriptions
Task period = 60 ms and SampTime = 100 ms
The task period is less than SampTime, so DIP processing is not executed every period.

Time
Not executed because elapsed time
(60 ms) < 100 ms.
Executed because elapsed time (60 + 60 ms = 120 ms) > 100 ms.
The remaining 20 ms is carried over.
