3.7.1 Command List
The command list stores the command list used by the DNP master port. This list
only must be defined if the DNP master port is used. Up to 300 commands can
be defined for the master port. The structure of each row in the list is shown in
the following table.
Word Offset Definitions
0 Port/Flags
1 Slave Address
2 Object
3 Variation
4 Function
5 Address in Slave
6 Point Count
7 DNP DB Address
8 IED DB Address
9 Poll Interval
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 depends 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)
