Note 1: A default variation refers to the variation responded 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. See the Communications section in Chapter 5
of the Instruction Manual for details. This optimizes the class 0 poll data size.
Note 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.)
Note 3: Cold restarts are implemented the same as warm restarts, meaning that the UR is not restarted, but the DNP process is restarted.
