4.5 Address space
Address space of the analog input module AI 4×RTD/TC 2-/3-/4-wire HF
The following figure shows the assignment of the address space with value status (Quality

enabled.
Figure 4-9
Configuration options of the AI 4xRTD/TC 2-/3-/4-wire HF
The following configurations are possible:
● Configuration 1: Without value status
● Configuration 2: With value status
Evaluating the value status (as of firmware version V1.01)
An additional byte is occupied in the input address space if you enable the value status for
the analog module. Bit 0 to 3 in this byte is assigned to one channel and provides
information on the validity of the analog value (0 = value is incorrect).
