1. When Input TRG is at Status 1, Output Q changes at once to Status 1. When
Input TRG changes from 1 to 0 (i.e. the descending edge comes), the internal
time delay timer of FAB is activated and the Output Q still remains at Status 1.
When the set time T is over, Output Q becomes 0 and the timer is reset.
