The definition of each parameter required for each command is provided in the
following table.
Bits in the Port/Flags parameter are dependent on the data type. The following
table defines the Port/Flags bits for binary input, analog input and counter data
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 RBE Flag (0=Events from IED, 1=Events by module) 8
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, 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 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.
