Testing
Use the TEST DB2 command to test the data mapping from the relay to your
DNP3 master. You can use the TEST DB2 command to force DNP3 values by
object type and label. Although the relay reports forced values to the DNP3 host,
these values do not affect protection processing within the relay. The TEST DB2
command operates by object type and label, so it works equally well with custom
mapping and the default DNP3 maps. See TEST DB2 on page 14.56 for more
information.
When you are using the TEST DB2 command to test DNP3 operation, the Relay
Word bit TESTDB2 will be asserted to indicate that test mode is active. The
DNP3 status bit will also show forced status for any object variations that include
status.

Object List
Table 16.8 lists the objects and variations with supported function codes and
qualifier codes available in the relay. The list of supported objects conforms to
the format laid out in the DNP3 specifications and includes both supported and
unsupported objects. Those that are supported include the function and qualifier
codes. The objects that are not supported are shown without any corresponding
function and qualifier codes.
NOTE: The TEST DB2 command will
override the state of all instances of
the forced bit or value for all active
CADI2 protocols. This includes DNP3
serial and LAN/WAN and IEC 61850
GOOSE and MMS. Before using the
command, take precautions to ensure
against unintended operations from
inadvertent messages sent as the
result of a TEST DB2 override, for
example, a bit used to trip a breaker
on a remote relay via IEC 61850
GOOSE.
