When the timer setting value is 2 (2 × 100ms), the scan time is 110ms, and the timer limit setting is 100ms
Ex.
If the coil of the timer (T0) is turned on at the next scan after the values satisfy "Count at execution of the
END instruction  Timer setting value", the coil and the contact are simultaneously turned on because the
values satisfy "Timer current value = Timer setting value" at the start of the timer.
