Siemens DQ 16x24VDC/0.5A HF User Manual page 22

Value status (Quality Information, QI)
The value status is always activated for the following module names:
● DQ 16x24VDC/0.5A HF QI
● DQ 16x24VDC/0.5A HF S QI
● DQ 16x24VDC/0.5A HF MSO
An additional bit is assigned to each channel for the value status. The bit for the value status
indicates if the output value specified by the user program is actually pending at the module
terminal (0 = value is incorrect).
Note
The maintenance interrupt "Limit value warning" has no effect on the value status.
