Socket Services
9-3-1

Overview

Socket services on the built-in EtherNet/IP port are used to exchange data between Controllers and
general-purpose applications that do not support CIP message communications. The Controller
requests the socket service from the user program.

NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual (W506)
At the host, system calls of sockets, e.g.,
from a C language interface library, can
be used to directly use TCP/IP or UDP/IP
to access Controller data.
Built-in EtherNet/IP port
Data
At the Controller, socket instructions can
be executed in the user program to
directly use UDP or TCP to exchange
data with the host computer.
