This parameter determines how the Timer Input Signals affect the Run/Stop
status of the Timer. Timing diagrams are shown below for level active and edge
triggered (1-input or 2-input) operation. For single input modes (Input A only),
Input B provides a level active Timer Inhibit function. In the Display Hold
mode, the timer display value remains held and only updates when a Timer
Start (Input A) or Timer Stop (Input B) edge occurs.
The timer reset (&+!) operating modes are identical to the other modes in the
diagrams, except the timer display value is reset at the Time Start edges.
The Timer can also be stopped at a Timer Stop Value or at Setpoint output
activation or deactivation. This type of Stop condition is cleared when a Timer
Reset occurs, or another start edge is applied on the timer input.
For Reset Modes (&+!), the timer is reset at Time Start edge.

TIMER START VALUE
The Timer returns to this value whenever a Timer Reset occurs. The value is
entered in the same display format as the Timer Range selected. Non-zero
values are normally used for “timing down” applications, but they can also
provide an offset value when timing up.
