Although some SCADA professionals still find it hard to grasp. There is a fundamental difference between SCADA systems and IIoT. It is the use of the internet as the backhaul network of communication in IIoT, as opposed to proprietary point-to-point (p2p) protocols in SCADA and DCS systems. While internet communication has, for two decades, totally transformed other sectors. It remains difficult for legacy industrial machines, devices and PLCs to share the stream of information passing through them with web services, analytics apps e.t.c And at the forefront of this siloed industrial environment is the Modbus Protocol, which is arguably the most common p2p protocol today. In fact, Modbus creates silos to such an extent that even two devices from different suppliers that both talk Modbus cannot easily exchange data with each other. The most logical solution to unlock the value trapped behind the walls of p2p protocols is to use an IIoT gateway to bring the data to a level where inter-connectivity with the cloud platforms and other machines can be easily facilitated. In the video below I demonstrate how to read Modbus and data from add-on sensors into an internet ready platform such as the Raspberry Pi with Windows 10 IoT Core.
