OT and Industrial Control Systems
OT stands for Operational Technology, used in industrial production. This chapter will focus on existing control systems prevalent in the industry, commonly attributed to the OT layer. These are part of layers 0, 1, and 2 of the Purdue model and ISA-95 architecture. This chapter will help you understand real-time manufacturing execution systems and how machines are orchestrated to maximize production.
In Chapter 2, Anatomy of an IoT Architecture, we outlined a layered approach to architecture. This chapter will focus on the lower layer and move toward an end-to-end integration. The device layer, or the lowermost layer, consists of machines that operate, PLCs that help the machines run, and the SCADA and control ...
