Open Platform Communications (OPC) is one of the important communication protocols for Industry 4.0 and the IIoT (Industrial Internet Of Things). OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol used for industrial automation. OPC UA provides a flexible and adaptable mechanism to move data between enterprise systems, monitoring devices, and sensors that interact with real-world data. You can use OPC UA to establish communication for simple downtime status or for massive amounts of highly complex plant-wide information.

The OPC UA source is a client that collects data from OPC servers. Data points in OPC are tags that represent data from devices and provide real-time access to data. In a

task, you can create an OPC UA source to read the incoming data based on the list of tags that you provide. You must mention the tags in a JSON array format.
