Counter

Select this heading from the pull-down menu to access individual counters. See figure below:

Figure 55–Counter access window

Summary: The Counter feature allows the tracking of event occurrences for any signal that the controller
software is able to monitor as an equation. Any signal that is viewable through the equation builder is
available.
Enable: Check the Enable checkbox to activate the counter.
Line Value: Current count value. The reset button will set the value to 0.
Count Event: The Count Event is an equation entry indicating the condition to count. This equation is
used to detect transitions. For example, if the equation is set to [AC Main] > 24, the counter will trigger
when the voltage moves from 24 volts or less to above 24 volts.
Reset Event: The Reset Event is the trigger condition that sets the Count value back to 0.
General Note: The Timer and Counter values themselves can be used in equations. They can monitor
each other.

6.6.2.10 Timers

Select this heading from the pull-down menu to access individual timers. See figures below:

Figure 56–Timers access windows

Enable: Check the Enable checkbox to activate the timer.
Increment/Decrement: This indicates whether the timer counts up or down from the initial value.
Initial Value: Set the starting value for the time. The time format is shown above the fields as
DDDD:HH:MM:SS, which means 4 digits for days, 2 digits for hours, minutes, and seconds.
Line Value: Current time value for the timer.
Run Event: Trigger equation indicating a timer start.
Stop Event: Trigger equation indicating a timer stop.
Note (Run/Stop): The Run Event acts as a level detector if the Stop Event is left empty. With a set Stop
Event, the Run Event acts as an edge detector where a transition will cause the timer to start, but the
same event in the reverse direction will not cause the timer to stop. This allows the Run and stop events
to be completely separate and unrelated events.
General Note: The Timer and Counter values themselves can be used in equations. They can monitor
each other.
