Reading Event
Time Stamps
Each alarm condition has an associated time stamp. This time
stamp tracks the most recent occurrence of the out-of-tolerance
condition. The time stamp indicates the earliest time at which
the most recent out-of-tolerance condition was detected.
In general, the time stamps may be read using a query of the
form:
<attribute>:ALARM:TIME?
-- read the time of the event
<attribute>:ALARM:DATE?
-- read the date of the event
Where <attribute> is replaced by a keyword which indicates
which attribute’s out-of-tolerance time stamp is to be read. The
valid queries are:
