With adoption of Internet of Things (IoT) and Industry 4.0 functions, devices are increasingly connected via industrial protocols. What’s more, today’s machine to machine (M2M) communications are rapidly standardizing on these protocols. Complicating matters is that IoT protocols don’t describe a single application-layer protocol, as several standards are in operation. So, while early IoT implementations used standard Internet protocols, there are also dedicated IoT protocols now available. Modelling communication structures and identifying the right protocol for a particular application
can be daunting. This article outlines what various protocols do as well as the options available for these protocols – so design engineers can more easily select the most suitable to integrate. Defining the application- layer protocol for industrial networks The structures of communication protocols for digital M2M and IoT systems are conceptually broken into abstract layers, with the most common models having three, four, five, or seven layers. These conceptual frameworks assume
Figure 1: IIoT functions in industrial automation rely on increasingly connected devices employing industrial protocols for networking. The abstracted layers of these networks require no knowledge of underlying layer functions … which is why so much design engineering focuses on machine networks’ top (application) layer.
