[DNP Master Slave List]

The [DNP MASTER SLAVE LIST] section is only used if the module is simulating

a DNP master device. This list defines the protocol specific information for each

IED unit to be interfaced with on the master port.
The slave list is formatted differently than the other sections of the configuration

file. Each IED unit is present on a separate line in the section between the labels
START and END. These labels inform the program where the lists starts and

stops. The module's program will parse each IED unit's information from each

line and place the data in the module and will continue reading records until the
END
label is reached or the maximum number of slave are processed.
The following table describes the format of each record.

Column

Variable
Name

Data Range

Description

IF Error

Config. Value

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 Time-
out

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
Time-out

1 to 65535
milliseconds

Time-out period the master will wait for
each response message fragment. If data
link confirms are enabled, make sure the
time-out period is set long enough to
permit all data confirm retries.

5000

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.

the DNP master slave definition list.

# DL Conf Mode ==> 0=Never, 1=Sometimes and 2=Always (select 0).
