When you specify the counting direction, you determine how the comparison
value/start value parameter will be used.
Counting up:
The transferred value is the comparison value.The following happens when a
counter is started.
-- Counting begins with the start value
²
0.
²
-- The counting value is incremented with each encoder pulse.
When the counting value reaches the specified comparison value, the para-
meterized reactions are triggered (e.g., reset digital output, trigger hardware
interrupt).
Counting down:
The transferred value is the start value. The following happens when a count-
ing procedure is started.
-- The counting value is set to the specified start value.
-- The counting value is decremented with each encoder pulse.
When the counting value reaches the comparison value
²
0,
²
the parameter-
ized reactions are triggered (e.g., reset digital output, trigger hardware inter-
rupt).
The comparison value/start value can be specified for a specific channel.
