• Event sub-classes in the range of 0x40 to 0x7f are Level 2 events. When a unit has been
configured to log Level 2 events, all events with sub-classes 0x00 to 0x7f will be logged.
Level 3 events are all events with sub-classes of 0x80 and higher.
• A unit set to Level 3 will log all events.
Levels 2 and 3 should be used for data that would not normally be included in the event logs
but may be required under special conditions. The Level 2 events would normally contain
more detailed information than Level 1 events and less than Level 3 events. The designations
for the event classes are as follows:
