DNP3 implementation table
The following table identifies which object variations, function codes, and
qualifiers the IED supports in both request messages and in response messages. For
static (non-change-event) objects, requests sent with qualifiers 00, 01, 06, 07, or
08, will be responded with qualifiers 00 or 01. Requests sent with qualifiers 17 or
28 will be responded with qualifiers 17 or 28. For change-event objects, qualifiers
17 or 28 are always responded.
