3.5.2 Delayed activation mode. TG2 input.
This mode applies a delay between the activation of the trigger input TG2 and that of the
timer status output "T". The time delay is set by the time constant.
With TEN=1 and TRS=0, the timer is activated with an up-flank at the TG2 input. At that
instant, the timing "t" begins from "0".
Once the time indicated with the time constant has elapsed, the timing is over, it activates
the timer status output (T=1) which remains high that until a down-flank at trigger input TG2
occurs.
The elapsed time (t) is maintained until a new up-flank occurs at trigger input TG2.
If the down-flank at input TG2 occurs before the indicated time has elapsed, the PLC stops
timing and it keeps the "t" value it has at the time.
Operation of the TRS input in this mode.
If an up-flank occurs at the TRS input while timing or after it, the PLC resets the timer setting
its status output low (T=0) and resetting its timing (t=0).
Since the timer is reset, its trigger input must be activated again to turn it back on.
