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. Default variations are configurable. However, default
settings for the configuration parameters are indicated in the table above.
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 except for object 70, which responds
with qualifier 1B or 5B.
Note 3
: For the AT Communications Module, a cold restart is implemented as a
warm
restart. The executable is not restarted, but the DNP process
is
restarted.
Note 4
: Writes of Internal Indications are only supported for index 7 (Restart IIN1-7), and
indices 16 and beyond (user-defined indications).
