Timer.#.TimerInput
The Timer Input event is level sensitive (not edge only) and is used to define when the Timer starts counting against the Preset
(along with the Timer Type). See the various timing diagrams in Figure 67 through Figure 76 to see how the Timer Input affects
the Timer Output.
Timer.#.TimerReset
The Timer Reset event is used to reset the ElapsedTime to zero and deactivate the TimerOutput and TimerActive. Level On
and Level Off timer types do not utilize the reset, as they reset automatically based on the state of the Input.
The Reset is a self-clearing function meaning that the reset occurs on the rising edge of the Reset input, and internally the
reset is set off. Therefore a timer can immediately begin counting again even if the user holds the Reset input ON. Additionally,
when resetting a timer in user program, the user must only set the Reset ON, and the controller will automatically set it off.
There is no reason for the user to force the Reset OFF within the program.
Output Events / Destinations
The following signals are available in user programs and as Sources on the Assignments view.
Timer.#.TimerOutput
The Timer Output state is controlled by the Timer Input, the Timer Type, and the other configuration settings of the Timer
object. See the various timing diagrams in Figures 2 through 10 to see how Timer Output functions.
The Timer Output can be assigned to multiple Destinations on the Assignments view just as any other Output Event.
Timer.#.TimerActive
The TimerActive event is used as an indicator that the Timer is actively counting (i.e. In the case of an OFF Timer, the Active
event would not activate until the Input turns OFF.).
In the case of Cumulative timers, the Active does not remain on even though the Elapsed Time may be non-zero, if the timer is
