Figure 83 — Counter access window
Summary: The Counter feature allows the tracking of event occurrences for any signal that the controller
software can 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 sets 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 triggers 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 Counter values themselves can be used in equations. They can monitor each other.

6.7.2.11 Counters
Select this heading from the pull-down menu to access individual counters.
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 causes the timer to start, but the same
event in the reverse direction does not cause the timer to stop. This allows the Run and stop events to be
completely separate and unrelated events.
General Note:
The Timer values themselves can be used in equations. They can monitor each other.
