This chapter introduces some of the most important and commonly used functions of UA I/O and their
setting steps.
OPC UA I/O modules is a series of Ethernet I/O modules that built-in with the OPC UA Server and MQTT
Client services . The OPC UA I/O module, also called UA I/O or U-7500, supports the OPC UA server and
MQTT client function in industrial networking communication. Users can choose the networking mode
according to their needs and environment, to transmit the values of built-in I/O channels to the cloud IT
system or field control system for reading and writing. So, the main functions are the OPC UA connection
and the MQTT connection. This chapter will introduce them first. Each function can be divided into the
settings for the Server/Broker and Client, and how to enable secure encrypted communication, and how
to download/upload the secure certificates. In addition, the AI/AO, DI/DO function applications are also
very important for the UA I/O, which will be added to this chapter soon.
