FINS/UDP Method
Section 8-2
UDP Port Numbers for
FINS/UDP
The UDP port number is the number for UDP to identify the application layer
(i.e., the FINS communications service in this case). When communications
are executed by UDP/IP, this port number must be allocated to the communi-
cations service.
The default setting for the UDP port number (i.e., the UDP port number of the
EtherNet/IP Unit or built-in EtherNet/IP port) is 9600. To set another number,
set the number on the FINS/UDP Tab Page of the CX-Programmers Edit
Parameters Dialog Box.
At the EtherNet/IP Unit or built-in EtherNet/IP port, a UDP/IP frame received
with a FINS/UDP port number is recognized as a FINS frame.
Procedure for Using FINS/UDP
1,2,3...
1.
Make the basic settings.
Refer to Initial Settings in 3-1-1 Procedures.
2.
Keep the CX-Programmer connected online, right-click the EtherNet/IP
Unit or built-in EtherNet/IP port in the PLC IO Table Dialog Box, and select
Edit - Unit Setup. Set the following in the CPU Bus Unit Setup Area from
the FINS/UDP Tab Page of the Edit Parameters Dialog Box.
• IP Address Conversion
• FINS/UDP Port No. (Default: 9600)
• IP Address List (Set only when the conversion method is set to IP ad-
dress table.)
• Dynamic Change of remote IP addresses
3.
Select Transfer to PLC from the PLC Menu and click the Yes Button. The
setting data will be transferred to the CPU Bus Unit System Setup Area in
the CPU Unit.
4.
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.
5.
Create a ladder program that includes the SEND(090), RECV(098), and
CMND(490) instructions.
Note
Routing tables are required in the following situations:
• When communicating with a PLC or computer on another network (e.g.,
remote programming or monitoring using FINS messages or a CX-Pro-
grammer).
• When multiple Communications Units are mounted to a single PLC (i.e.,
CPU Unit).
• When routing tables are used for one or more other nodes on the same
network.
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.
