5 Sysmac Studio Settings for the Built-in EtherNet/IP Port
Description
Set whether to use the remote node keep alive function of
connected servers and clients (such as socket services,
FTP server, Sysmac Studio, and FINS/TCP) for each con-
nection number. If the Use option is specified in Keep Alive,
the transmission of Keep Alive packet starts after the speci-
fied Keep Alive monitoring time when no communication is
performed with the remote node.
If the remote node does not respond for longer than the
keep alive packet transmission + resending 5 seconds x 5
*1
times , the connection is disconnected.
The connection is left open if the power supply to the
remote node is turned OFF without warning. Use the keep-
alive function whenever possible.
• Use.
• Do not use.
This is the time until the transmission of Keep Alive packet
is started.
Setting range: 1 to 65,535 (seconds)
Set whether to specify the Linger Option for connections to
FINS/TCP or socket services. If the Linger Option is speci-
fied, the port number is immediately opened even before
the port number is released after the socket closes (approx.
1 minute).
• Specify.
• Do not specify.
Description
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. Also
set these settings to use an NX-series CPU Unit as an IP
router using the IP routing function of the built-in Ether-
Net/IP port.
The registration number of IP router table you can set are
up to 128 with an NX701 CPU Unit, up to 64 with an NX102
CPU Unit, and up to eight with an NJ-series CPU Unit and
an NX1P2 CPU Unit.
