Where n designates the index of the displayed item as shown by the EXAMINE LIST
command (See page for more details).
Example:
Suppose n=9 corresponded to the displayed ANALOG OUTPUT value. The command X 9
might result in the response:

EXCEPTION REPORTING
Exception Reporting is used to send out a report whenever an alarm condition is present. As soon as an alarm
condition occurs, the unit sends out the following information over the RS-232 lines:
The Unit ID number
The Time and Date
The Alarm Condition(s)
The unit will then send this information out, along with the print list selected, every print interval (of the print interval
is greater than 0.24999 minutes).
Each time an alarm condition is corrected, another exception report will be generated stating that the alarm
condition is no longer present.
NOTE: Even thought the alarm condition may have been corrected and the report sent out, the alarm relay will
NOT shut off until cleared through the front keypad or the RS-232 link.
