Column Variable Name Data Range Description IF Error
6 Slave Mode Coded Value
(Bit
0=Enable, Bit
1=Unsol Msg,
Bit 2=Use
DM, Bit
3=Auto Time
Sync) This word contains bits that define
the slave mode. The slave mode
defines the functionality of the
slave device and can be
combined in any combination. The
fields have the following definition:
Enable: determines if this slave
will be used.
Unsol Msg: causes an enabled
unsolicited response message to
be sent to the slave when its
RESTART IIN bit is set. This
parameter is also required for
unsolicited message reporting by
the IED unit.
Use DM: uses delay
measurement.
Auto Time Sync: time
synchronization used when NEED
TIME IIN bit set. 5
2.2.13 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, 3=Port 3).
Any value from 1 to 3 sends out P2 (Master Port) 0 to 3
2 Enable/Disable Command (1=Enable, 0=Disable) 4
3 RBE Flag(0=Events from IED, 1=Events by module) 8
