TIMERS AND TIMER STATUS BITS (T MEMORY TYPE)
Timer status bits provide the relationship between the current value and the preset value of a selected timer. The timer status bit will be on when
the current value is equal or greater than the preset value of a selected timer. In this example, when input I03 turns on, timer T01 will start.
When the timer reaches the preset of 5 seconds timer status contact T01 turns on. When T01 turns on, output Q04 will turn on. Turning off I03
will reset the Timer.
