2.3 Slave List
The slave list defines the IED units and their specific communication parameters
for a DNP master port. Up to 40 IED units can be defined in the module to be
associated with the master port. The structure of each row in the list is defined in
the following table.
Column Variable Name Data Range Description If Error
1 DNP Slave Address 0 to 65534 This is the slave address for the unit to
override the default values.
Ignore
2 Data Link Confirm Mode Coded Value
(0 = Never, 1 =
Sometimes,
2 = Always)
This value specifies if data link frames sent
to the remote device require a data link
confirm. This value should always be set to
zero for almost all applications.
0
3 Data Link Confirm Tout 1 to 65535
milliseconds
This parameter specifies the time to wait for
a data link confirm from the remote device
before a retry is attempted.
300
4 Maximum Retries for Data
Link Confirm
0 to 255 retries Maximum number of retries at the Data Link
level to obtain a confirmation. If this value is
set to 0, retries are disabled at the data link
level of the protocol. This parameter is only
used if the frame is sent with confirmation
requested.
3
5 Application Layer Response
Timeout
1 to 65535
milliseconds
Timeout period the master will wait for each
response message fragment. If data link
confirms are enabled, make sure the
timeout period is set long enough to permit
all data confirm retries.
5000
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
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.
2.4 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
