6.5.2 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.
If the timer is initialized with values TEN=1 and TRS=0, the timer will be activated when a leading
edge is produced at TG2 input. At that instant, the timing "t" begins from "0".
Once the time specified by the time constant has elapsed the timing operation will be considered
as having completed and the timer status output (T=1) will be activated and will remain in this status
until the trailing edge is produced in the trigger input TG2.
The elapsed time will remain as a timer time value (T) once timing has been completed.
If, once the timing has finished, it is required to activate the timer again, another leading edge must
be produced in the TG2 input.
If the trailing edge of the trigger input TG2 is produced before the time specified by the time constant
has elapsed, the PLC will consider that the timing operation has concluded, maintaining the time
count it had at that moment as the timer time (T).
