TON: When the value of the input “ IN ” is equal to 1,
timer starts time.Timer current value of Txxx is the
current time (a multiple of the time base).When the
current value of the timer is equal to the preset time (PT),
the value of the timer bit is 1.When the value of the
input “ IN ” is equal to 0, timer current value is cleared.
