Represents four true or false flags that indicate the general health of an analog output. Three flags are associated with the values of other attributes of the object.
The four flags are:
- In Alarm - In Alarm flag is False (0) if the Event State attribute value is Normal; otherwise, the In Alarm flag is True (1).
- Fault - Fault flag is True (1) if the Reliability attribute is not reliable; otherwise, the Fault flag is False (0).
- Overridden - Overridden flag is Logical 1 if the Present Value is decoupled from the hardware output because operator intervention provided a different value or local override is active.
- Out of Service - Out of Service flag is True if the Out of Service attribute value is True; otherwise, the Out of Service flag is False.
