For each connection number, set whether to use the Keep Alive
function to check if the connected client nodes, such as FTP
server functions, Sysmac Studio, TCP/UDP message service
(TCP only), are communicating.
If the Keep Alive function is set to Use, and a remote node does
not respond during the monitoring time set in the Keep Alive
monitoring time setting, the connection to the remote node is
disconnected.
The connection to a remote node is left open if the power supply
to the remote node is turned OFF without warning. Use the Keep
Alive function whenever possible.

Net/IP port.
This setting is not required when the default gateway is not used.
Set these settings when the built-in EtherNet/IP port is used for
tag data links or CIP message communications with nodes on
other IP network segments via an IP router. Accordingly, set
these settings when you use a Communication Control Unit as
an IP router using the IP routing function for the built-in
EtherNet/IP port.
You can set up to 64 combinations of IP addresses and gateway
addresses.
Specify 0 for the host portions of the IP addresses.
