Via 'Basic parameters' you can reach 'Select interrupt' . Here you can define the inter-
rupts the CPU will trigger. The following parameters are supported:
None: The interrupt function is de-activated.
n
n Process: The following events of the frequency measurement can trigger a hardware
interrupt (selectable via 'Frequency counting' ):
– End of measurement
Diagnostics and process: A diagnostics interrupt is only triggered when a hardware
n
interrupt was lost.
Default values and structure of this dialog box depend on the selected 'Operating mode' .
The following parameters are relevant for frequency measurement, which must be speci-
fied or determined:
1 Integration time
2 Counting pulse
3 SW gate
4 Evaluated frequency
