1) A default variation refers to the variation responded when variation 0 is requested and/or in class 0, 1, 2, or 3 scans. Default variations
are configurable; however, default settings for the configuration parameters are indicated in the table above.
2) For static (non-change-event) objects, qualifiers 17 or 28 are only responded when a request is sent with qualifiers 17 or 28,
respectively. Otherwise, static object requests sent with qualifiers 00, 01, 06, 07, or 08, will be responded with qualifiers 00 or 01. (For
change-event objects, qualifiers 17 or 28 are always responded.)
3) Writes of internal indications are only supported for index 7 (Restart IIN1-7)
4) Cold and warm restarts return an application layer acknowledge, but no restart action is taken.
