For Industry 4.0 application, an OPC UA Server will be the virtual interface between the cloud and the sensors in the field.

Therefore, the OPC UA Server has to apply the following functions:

Find all IO-Link Masters

Find IO-Link Devices

Download IODD of connected devices

Build up information model

Record all replacement of connected devices and update information model

Capture the status of connected devices
