 Timing Chart:
Case 1： TOF1_PT is the set time for off delay. When TOF1_In is TRUE, TOF1_Q is TRUE.
When TOF1_In is FALSE, the timer starts to measure the time. When the value of
TOF1_ET equals the setting value of TOF1_PT, TOF1_Q is FALSE and the timer stops
timing.
Case 3： When TOF1_In changes from TRUE to FALSE, the timer starts timing. When current
time (TOF1_ET) is less than the set time (TOF1_PT) and TOF1_In is set to TRUE,
TOF1_ET is reset and the state of TOF1_Q does not change.
