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, 2=Port 2) 0 or 2
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 depends 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. Verify that 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.
Function
This parameter specifies the DNP function for the command list object. The
object type determines the value of the functions permitted. For example, the
only function permitted for binary input data points is the read function (Function
Code 1). For counter and output objects, more functions are available.
Address In Slave
This value must be greater-than or equal to zero. If it is set to a value less-than
zero, the command will be ignored. This parameter specifies the starting point
address to consider in the IED unit.
