Address space

Abbreviations
● "IB" stands for input byte, that is, the module start address in the input area
● "QAIn" stands for value status (QI) of analog input n
Evaluating the value status
One bit value status each exists for each analog input in the input address space.
Irrespective of the diagnostics enables, each value status (each QI bit) provides information
on the validity of the corresponding process value.
● Value status = 1: Process value okay, "good"
● Value status = 0: Process value not okay, "bad"
Basically, the value status is set to "good" when the analog value can be acquired without
error. The value status is set to "bad" in the following cases:
● The analog value cannot be acquired to a fault or error.
● The analog input is disabled.
