Number of consecutive occurrences
*1
: For alarm codes, refer to "Data Format [10]: Alarm Code" in this section.
This gives the contents of the alarm that occurred and the number of consecutive occurrences of the
alarm.
Example: Last Alarm History/Number of Consecutive Same Alarms (3011-06 hex) = 021B hex
02 1B
→ Number of consecutive occurrences of the same alarm: 2, Alarm code: 1B hex = 27
