9 TCP/UDP Message Service Function
9-1
Overview of the TCP/UDP Message
Service Function
The Communication Control Unit supports the TCP/UDP message service.
You can use the TCP/UDP message service from a PLC or general-purpose computer that does not
support the EtherNet/IP protocol to make settings in the Communication Control Unit, control I/O, and
perform troubleshooting.
You can send TCP/UDP commands from a device that supports the TCP/IP protocol or UDP/IP proto-
col (socket communications) to access CIP objects in the Communication Control Unit and thereby
control the Communication Control Unit. For details on request commands, refer to 8-4 CIP Object
Services on page 8 - 11.
Sysmac Studio also allows you to enable and disable the TCP/UDP message service function. Refer
to A-1-7 TCP/UDP Message Service Settings Display on page A - 13 for details.
