The standard IIoT flow

In Chapter 2, we looked at how industrial data is generated, gathered, and transferred to the cloud by familiarizing ourselves with computer-integrated manufacturing (CIM). We also looked at industrial equipment, such as DCS, PLCs, and SCADA, and network protocols, such as Fieldbus, ControlBus, and OPC. This gave us a picture of the whole path of industrial signals, from when they are generated by sensors in a factory to when they are processed in the cloud. In Chapters 3 and 4, we talked in detail about data acquisition, data sources, related protocols, and the edge devices used to push data into the cloud. This has shown us how data acquisition is the foundation of the IIoT and how we need to be compliant with several security and safety standards. Data, therefore, must be analyzed and processed. In a typical new IIoT architecture, there are other parallel mechanisms, such as central data storage and data processing and execution.
