Value status (Quality Information, QI)
The value status is always activated for the following module names:
● AI 8xU/R/RTD/TC HF QI
● AI 8xU/R/RTD/TC HF S QI
● AI 8xU/R/RTD/TC HF 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).
Address space of the AI 8xU/R/RTD/TC HF and AI 8xU/R/RTD/TC HF QI
The following figure shows the address space allocation for the configuration as a 9-channel
module. You can freely assign the start address for the module. The addresses of the
channels are derived from the start address.
"IB x" stands, for example, for the module start address input byte x.
