Hands-On Industrial Internet of Things

Summary

In this chapter, we learned how to implement the I-IoT data flow in a complex industrial plant. We started by looking at OPC, including what it is, how it has evolved, and how it works in both its implementations—OPC Classic and OPC UA. We explored how it connects to data sources to expose their data through common interfaces, following a common data model. We then went into detail about the edge, analyzing its features, internal components, architecture, interfaces, and current implementation.

After that, we started our journey on the I-IoT data flow. We looked at how to select a data source to connect to in order to gather data. We explored controllers, such as the PLC or the DCS, a SCADA system, and a Historian system. Each of ...
