Keep Alive Interval (x1 s)
This parameter specifies a time interval for TCP Keep Alive mechanism.
If the timer times out, the MicroLogix 1400 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 MicroLogix 1400 deems the TCP connection broken and
closes the TCP connection.
The valid range is 1 to 65535. Default value is 10.
Slave Node Address
This value is a node address of this DNP3 Slave.
The valid range is 0 to 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 to 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 to 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.
