Procedure for Using FINS/TCP

Make the basic settings.
Refer to Section 2 Startup Procedure in the Operation Manual Construction of Net-
works.
Make the settings in the Unit Setup.
With the CX-Programmer connected online, select the Ethernet Unit in the CX-Program-
mer's I/O Table Window. Right-click, and select Unit Setup. Then make the following set-
tings in the Unit Setup Window.
Setup Tab
• FINS/TCP port (Default: 9600)
FINS/TCP Tab
• Remote IP addresses (when client)
Note: When functioning as a server, set the permitted client IP addresses only when
protection is in effect.
• Automatically allocated FINS node addresses
Note: The functions of these items are described in detail in the Operation Manual Con-
struction of Applications, SECTION 7 Using FINS Communications to Create Host
Applications. Normally the defaults should be used.
• Keep-alive setting
Note: Normally this should be selected to be used.
• IP addresses protection setting
Note: Check this only for protection as the server.
Make the routing table settings and transfer them to each PLC. (See note.)
Set the routing tables with CX-Integrator, and transfer it to each PLC.
Create a ladder program that includes the SEND(090), RECV(098), and CMND(490)
instructions.
Even if the connection is closed at the FINS/TCP client, requests continue to
be made to the FINS/TCP server every few seconds to open a connection.
After the Ethernet Unit is powered up or restarted, the IP address for the con-
nection used as the FINS/TCP client is the remote IP address set under the
FINS/TCP Tab in the Unit Setup.
To dynamically change the remote IP address (i.e., during CPU Unit opera-
tion), execute the CMND(490) instruction in the ladder program and send a
FINS command (FINS/TCP CONNECTION REMOTE NODE CHANGE
REQUEST; command code: 27 30 hexadecimal) to the Ethernet Unit.
Routing tables are required in the following situations:
It is not necessary to set routing tables if one Communications Unit is
mounted to the PLC and the nodes are connected as one network.
• When communicating with a PLC or computer on another network (e.g.,
• When multiple Communications Units are mounted to a single PLC (i.e.,
• When routing tables are used for one or more other nodes on the same
remote programming or monitoring using FINS messages or a CX-Pro-
grammer)
CPU Unit)
