Port/Flags Bits Description Decimal Equivalent
4 to 7 Not Used
For these data types the qualifier used in the data request is dependent on the
Point Count and Address in Slave fields in the command as follows:
If Point Count < 0, then use Qualifier 06h (All points, packed & -Point Count = #
of points to consider)
If Address in Slave = 0 & Point Count > 0, then use Qualifier 00h or 01h (points 0
to Point Count –1)
If Address in Slave > 0 & Point Count > 0, then use Qualifier 00h or 01h (Address
in Slave to Address in Slave + Point Count –1)
The following table defines the Port/Flags bits for binary output and analog output
points.
Port/Flags Bits Description Decimal
Equivalent
0 to 1 Communication port(0=Internal, 1=Port 1, 2=Port 2,
3=Port 3). Any value from 1 to 3 sends out P2 (Master
Port) 0 to 3
2 Enable/Disable Command (1=Enable, 0=Disable) 4
3 Poll Type (0=Poll, 1=Exception) 8
4 Data Source(0=DNP Database, 1=IED Database) 16
5 to 7 Not Used
For these data types the qualifier used in the data request is dependent on the
Point Count and Address in Slave fields in the command as follows:
If Address in Slave = 0 & Point Count > 0, then use Qualifier 17h or 28h (Point
Count specified starting at point 0)
If Address in Slave > 0 & Point Count > 0, then use Qualifier 17h or28h (points
from Address in Slave to Address in Slave + Point Count –1)
If Point Count <= 0, then ignore because this is illegal for outputs.
Slave Address
This parameter specifies the IED unit address on the DNP network to consider
with the command. The parameter has a range of 0 to 65535. The value of
65535 is reserved for broadcast messages. Be certain the slave configuration
information is set up in the module for each slave defined in the command list.
Object
This parameter specifies the DNP object type in the command. Valid objects for
the module are 1, 2, 12, 20, 21, 30, 32, 41, 50, 60 and 80. A value of 0 is
permitted in this field for a set of special commands.
Variation
This parameter is specific to the object type selected.
