ASCII Command Reference
Command Description
TEST DB OFF
Use the TEST DB OFF command to end the testing session and remove the
override values. The relay returns the database registers to the pretest values.
TEST DB2
The TEST DB2 command is used to test DNP3 and IEC 61850 MMS communi-
cation protocols.
TEST DB2
Other than Fast Message Protocol, all the communication protocols supported by
the relay (DNP3, IEC 61850, GOOSE) retrieve data from a storage area called
the CADI2 database. These data include both digital quantities and analog quan-
tities. All Relay Word bits along with additional binary input points in DNP3
map are available in CADI2 database as digital quantities.
Use the TEST DB2 command to override any value in the CADI2 database. Val-
ues you enter in the CADI2 database are override values read by the master sta-
tions.
The override value value1 can be logical 0 or logical 1 for digital and status ele-
ments. The analog value2 can be an integer or a floating-point number.
The Relay Word bit TESTDB2 will be asserted while there are points in this test
mode.
