Remote UDP Port Number for Initial Unsolicited
This value is used to configure Master UDP Port Number for Initial Unsolicited
Response if the parameter End Point Type is selected as Datagram Only.
The valid range is 0…65535. Default value is 20000.
Remote UDP Port Number
This value is used to configure Master UDP Port Number if the parameter End
Point Type is selected as Datagram Only.
The valid range is 0…65535. Default value is 20000.
Keep Alive Interval (x1 s)
This parameter specifies a time interval for TCP Keep Alive mechanism.
If the timer times out, the controller transmits a keep-alive message. The keep-
alive message is a DNP Data Link Layer status request
(FC_REQUEST_LINK_STATUS). If a response is not received to the keep-alive
message, the controller deems the TCP connection broken and closes the TCP
connection.
The valid range is 1…65535. Default value is 10.
Slave Node Address
This value is a node address of this DNP3 Slave.
The valid range is 0…65519. Default value is 1.
Local TCP Port Number
This value is used to configure Local TCP Port Number which is used for TCP
socket listening.
The valid range is 0…65535. Default value is 20000.
Local UDP Port Number
This value is used to configure Local UDP Port Number which is used for UDP
socket listening.
The valid range is 0…65535. Default value is 20000.
Diagnostic File Number
The diagnostic file number is used to store the diagnostics for the
troubleshooting of DNP3 Ethernet subsystem. The status of DNP3 TCP and
UDP subsystem is stores to this data file.
The value of this parameter is N file only. Valid range is 0, 7, 9…255. Default
value is 0.
