As soon as a positive edge at the "latch input" results from the counter
process, a recent counter value is stored in the according latch register.
The "input image" gives you access to the latch register.
The parameterization presets the behavior of the counter output:
• No comparison
• Counter value ≥ comparison value
• Counter value ≤ comparison value
• Pulse at comparison value
No comparison
The output is set like a normal output.
Counter value
≥
comparison value
If the counter value is equal or higher than the comparison value, the output
is set.
Counter value
≤
comparison value
If the counter value is smaller or equal than the comparison value, the
output is set.
Pulse at comparison value
When the counter reaches the comparison value, the output is set active for
the parameterized pulse duration.
If you've set a main counter direction, the output is only set off the main
counter direction at reaching the comparison value.
Pulse duration
The pulse duration tells for what time the output is set. It can be preset in
steps of 2ms between 0 and 510ms. Please regard that the counter pulse
times must be higher than the minimum toggle times of the digital output.
If the pulse duration = 0, the output is set active until the comparison
condition is not longer fulfilled.
The pulse duration starts with the setting of the according digital output.
The inaccuracy of the pulse duration is smaller than 1ms.
There is no finish triggering of the pulse duration if the comparison value is
not met for a short time during a pulse output.
