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.

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.
