Edge selection
Selects the edge that is counted:
● At rising edge:
The respective counter counts all rising edges at the digital input.
● At falling edge:
The respective counter counts all falling edges at the digital input.
Note
If the "Reverse direction" option is selected in "Set function of DI" and the counting direction
in the process changes, the counting edge is automatically adjusted (opposite edges).
Count direction
Count direction selection:
● Up:
The respective counter counts up.
● Down:
The respective counter counts down.
Note
This parameter has no effect if the "Reverse direction" option is selected in "Set function of
DI".
Set output
Selects the function that controls the response of the STS_DQ feedback bit (Page 44): You
use the feedback bit STS_DQ to control a digital output of a digital output module.
● Off (DQ = 0):
STS_DQ is independent of the counter value and permanently not set.
● Off (DQ = 1):
STS_DQ is independent of the counter value and permanently set.
● Between comparison value 0 and 1:
STS_DQ is set if counter value ≥ comparison value 0 and counter value ≤ comparison
value 1.
● Not between comparison value 0 and 1:
STS_DQ is set if counter value < comparison value 0 or counter value > comparison
value 1.
