The following show the examples of the coil and the contact being simultaneously turned on if the values are
set to become "Timer setting value < Scan time + Timer Limit Setting":
When the timer setting value is 1 (1 × 100ms), the scan time is 20ms, and the timer limit setting is
100ms
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.
When the timer setting value is 2 (2 × 100ms), the scan time is 110ms, and the timer limit setting is
100ms
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.
Figure 9.29 The coil and the contact are simultaneously turned on with the timer setting value being 1
Figure 9.30 The coil and the contact are simultaneously turned on with the timer setting value being 2
