For manufacturers, the promise of digital transformation lies in breaking down silos and gaining a holistic view across their entire operation, from asset data to insights across all manufacturing processes. An Industrial IoT (IIoT) solution relies on real-time and historical data from industrial devices and control systems located in manufacturing facilities. These include programmable logic controllers (PLCs), industrial equipment, supervisory control and data acquisition (SCADA) systems, manufacturing execution systems (MES), and process historians.
A modern IIoT solution goes beyond moving existing industrial processes and tools to the cloud. It involves transforming your operations and processes, embracing cloud-native services, and by using the power of machine learning and the intelligent edge to optimize industrial processes.
There are multiple stages in each of the three key phases shown in the preceding diagram. Each stage of an IIoT solution consists of multiple design patterns. You start your IIoT journey with connectivity as the first step. Computerization is the prerequisite step and it refers to enabling sensors and actuators to monitor production processes. Four key stages for a typical IIoT solution are highlighted in this guide.
