Based on machine to machine (M2M) communication processing, Opc Ua is used to define data transmission between two or even multiple devices, which can be wired transmission or wireless transmission. It belongs to the function of Internet of Things transmission, not limited to smart devices and data exchange. It also includes digital signal transmission of sensors and actuators, which is transmitted from on-premises to the cloud after edge computing for complex factory data transmission and analysis operations. Under the trend of Industry 4.0, the development from automation to intelligence achieves the so-called “Smart Factory”, which has the ability to optimize the production process of the factory by itself and expand without human intervention. Moreover, it is able to track in real-time, the entire production process, life cycle, utilization rate, cumulative production value and innovation, all of which can deploy IoT for learning through Opc Ua.
