Intermediate Analog Input VIs
This section describes the Intermediate Analog Input VIs that are used to perform analog
input functions. Intermediate Analog Input VIs provide greater flexibility and user
configuration than the Easy Analog Input VIs.
To access the ADAC Analog Input Easy VIs, choose Functions
>> User Libraries >>
ADAC
>> Analog Input. The Intermediate VIs are listed on the second line from the
top of the analog input palette:
•
ADAC AI Config
•
ADAC AI Start Device
•
ADAC AI Read
•
ADAC AI Clear
ADAC AI Config
The ADAC AI Config VI allocates and configures a device's A/D subsystem, returning a
Device Handle to be used in subsequent VI calls.
If the error in cluster contains an error from a previous VI call this VI does nothing, and
returns the error in cluster unmodified in the error out. In the event of a previous error the
Device Handle is set to -1.
