Overview

The CIP Messaging Communications Client function is available for an NJ/NX-series CPU Unit. This
function allows you to request a service by sending CIP messages to an external device and specifying
a self-contained object of a device supporting the CIP Communication Server functions.
The NJ/NX-series CPU Unit executes CIP communications instructions in the user program and send
CIP messages. In this way, you can use CIP messages to execute instructions such as reading and
writing variables (data) of the NJ/NX-series CPU Unit on the EtherNet/IP network.
