Procedure for Using FINS/UDP
Note
FINS commands can be sent to or received from other PLCs or computers on
the same Ethernet network by executing SEND(090), RECV(098), or
CMND(490) instructions in the ladder diagram program. This enables various
control operations such as the reading and writing of I/O memory between
PLCs, mode changes.

Executing, from the host computer, FINS commands with UDP/IP or TCP/IP
headers enables various control operations, such as the reading and writing
of I/O memory between PLCs, mode changes.
For example, it is possible to connect online via Ethernet from FINS communi-
cations applications such as the CX-Programmer, and to perform remote pro-
gramming and monitoring.
1. Make the basic settings.
Refer to 6-4-1 Overview of Startup Procedure .
2. Make the settings for FINS/UDP in the PLC Setup with CX-Programmer.
3. 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.
4. Create a ladder program that includes the SEND, RECV, and CMND
instructions.
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).
