Time intervals. Refer to the

4.11 Using Counters
Counters can be used to count TIME, DISTANCE, or count an event’s
occurrence. By using counters complex configurations can be created.
TIME and DISTANCE counters may be set to use a multiplicator
factor (or delta value) to count meters, kilometers, 10xkilometers,
seconds, minutes, days, etc. Counters’ configuration/manipulation is
controlled by the
GC
message. Up to 20 counters can be configured.
The count type (time, distance, situation) is set when the counter is
set to start a count.
There are three types of counters:
•
For counting time (TIMERS).
•
For counting distance (DISTANCERS).
•
For counting situations (COUNTERS).
For each counter a counter signal
Cxx
exists. A counter signal gets
true whenever the counter’s value exceeds a user-defined threshold
and gets low on the contrary. For example, a
time counter (TIMER)
set to count seconds with a threshold value of 300 will make a cor-
responding
Cxx
signal to become true 300 seconds after defining the
counter. See the next graphic to illustrate this.
