Note:
A Default v
ariation refers to the variation responded to when variation 0 is requested and/or in class 0, 1, 2, or 3 scans.
Note:
For static (non-change-ev
ent) objects, qualifiers 17 or 28 are only responded to 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 to with qualifiers
00 or 01. For change-event objects, qualifiers 17 or 28 are always responded to.
7.3.8.3 DNP3 INTERNAL INDICATIONS
The following table lists the DNP3.0 Internal Indications (IIN) and identifies those that are supported by the device.
The IIN form an information element used to conv
ey the internal states and diagnostic results of a device. This
information can be used by a receiving station to perform error recovery or other suitable functions. The IIN is a
two-octet field that follows the function code in all responses from the device. When a request cannot be
processed due to formatting errors or the requested data is not available, the IIN is always returned with the
appropriate bits set.
Bit Indication Description Supported
Octet 1
0 All stations message received
Set when a request is received with the destination address of the all stations
addr
ess (6553510). It is cleared after the next response (even if a response to a
global request is required).
This IIN is used to let the master station know that a "broadcast" message was
received by the relay.
