Default
FINS/TCP Port
Specify the local TCP port number to be used for the
FINS communications service. The TCP port num-
ber is the number used for TCP identification of the
application layer (i.e., the FINS communications ser-
vice in this case).
• Default (9,600)
• User defined (Setting range: 1 to 65,535)
0
(9,600)
No.
Shows the connection number. This is a network API
used when TCP is used for the FINS communica-
tions service. It corresponds to a socket in the socket
services. Up to 3 can be used at a time, and they are
identified by connection numbers 1 to 3. The PLC
can thus simultaneously execute the FINS communi-
cations service by TCP with up to 3 remote nodes.
Protect by IP
address
When this option is selected, if the PLC is set for use
as a server, and if a connection number other than
0.0.0.0 is set for a destination IP address, any con-
nection request from other than the number set for
that IP address will be denied.
Select this option to prevent faulty operation (by
FINS commands) from specific nodes from affecting
the PLC.
