Timing Chart:
Case 1
：
TON1_PT is the set time. When TON1_In is TRUE, the timer starts to measure the time.
When the value of TON1_ET equals the setting value of TON1_PT, TON1_Q is TRUE.
When the timer stops measuring time, TON1_In is reset to FALSE and TON1_ET and
TON1_Q are both reset.
Case 2
：
When the currently measured time of the timer TON1_ET is less than the set time
TON1_PT and TON1_In is reset to FALSE, TON1_ET is reset and the state of TON1_Q
does not change.
