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

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.
