Overview and Features

This section describes an overview and features of the OPC UA Server function.
1-1-1

Overview

The OPC UA Server function enables the NJ-series CPU Unit to operate as an OPC UA server. With
this function, OPC UA clients can connect via Ethernet to the built-in EtherNet/IP port of the NJ-series
CPU Unit using the OPC UA communications, and then read and write variables in the CPU Unit.
The OPC UA communications can simultaneously achieve both addressing security risks and connect-
ing with general-purpose methods. Therefore, the OPC UA Server function enables secure data
exchanges between the NJ-series CPU Unit and host systems such as SCADA or MES compatible
OPC UA so that the host systems can collect manufacturing progress information or issue manufactur-
ing instructions.
