Value status (Quality Information, QI)
The value status is always activated for the following module names:
● AI 8xU/I HS QI
● AI 8xU/I HS S QI
● AI 8xU/I HS MSI
An additional bit is assigned to each channel for the value status. The value status bit
indicates if the read in digital value is valid. (0 = value is incorrect).
