Comparator
The comparison value is specified via the output area. If a comparison condition is met, bit
STS_DO is set in the status word.
)
Note!
Please note that bit STS_DO can only be triggered if bit STS_CTRL_DO is set in
the status word.
By parameterisation you can define the response of the counter output:
ƒ Output never switches
ƒ Output switches if count value
³ comparison value
As long as the count value is greater than or equals the comparison value, the output
remains set
ƒ Output switches if count value
£ comparison value
As long as the count value is smaller than or equals the comparison value, the output
remains set.
ƒ Output switches at comparison value
Pulse at comparison value: If the counter reaches the comparison value, the output is set
for the parameterised pulse duration. If the pulse duration is = 0, the output is set until the
comparison condition is no longer met. If you have set a main counting direction, the
output is only switched from the main counting direction when the comparison value is
reached.
Pulse duration: The pulse duration indicates for how long the output is to be set. It can be
preselected in steps of 2.048 ms between 0 and 522.24 ms. The pulse duration starts with
the setting of the respective digital output. The inaccuracy of the pulse duration is smaller
than 2.048 ms. The pulse duration is not re−triggered if the comparison value has been
exited and reached again during one pulse output.

Note!
Together with bit STS_DO, bit STS_CMP is set in the status word. In contrast to
bit STS_DO, however, it remains set until it is reset with RES_SET in the control
word.
