FAST PATH:
1. A default variation refers to the variation response when variation 0 is requested and/
or in class 0, 1, 2, or 3 scans. The default variations for object types 1, 2, 20, 21, 22, 23,
30, and 32 are selected via relay settings. This optimizes the class 0 poll data size.
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
changeevent objects, qualifiers 17 or 28 are always responded.)
Cold restarts are implemented the same as warm restarts – the 869 is not restarted, but
the DNP process is restarted.
