Implementing the IIoT data flow
In this section, we will discuss the IIoT data flow. We will look at it first from the perspective of its architecture and network, and then move on to considering the strengths and weaknesses of each available data source option. So far in this book, we have not yet seen a situation in which industrial equipment is directly connected to the cloud. This is actually technically possible—there are several pieces of industrial equipment that have this ability—using internet protocols, such as MQTT, CoAP, and AMQP. Examples of this kind of equipment include complex packaging systems, automated guided vehicles (AGVs), robotized working cells, or the devices and equipment involved in a fully automated warehouse.
In this section, however, we are interested in industrial plants in which the factory floor is built and managed by thousands of sensors and actuators. In such a scenario, it is truly not possible to connect all these signals directly...
