IOT Vs Purdue Model

The Internet of Things (IoT) and the Purdue model are both related to the field of industrial automation and control systems.

The IoT refers to the network of physical objects embedded with sensors, software, and connectivity capabilities that enable them to collect and exchange data over the internet. IoT devices can include sensors, actuators, and other devices that are used in industrial automation systems.

The Purdue model, on the other hand, is a hierarchical reference architecture that organizes the different levels of an industrial control system into five layers. It provides a framework for integrating the different components of an industrial control system, from the physical equipment to the enterprise-level business systems.

In the context of industrial automation and control systems, IoT devices can be integrated into the different layers of the Purdue model to provide real-time monitoring and control of physical processes. For example, sensors and other IoT devices can be used in Level 0 to collect data on the physical equipment and processes, while devices like PLCs and DCSs in Level 1 can be used to control the physical processes based on the data collected by the IoT devices.

At higher levels of the Purdue model, IoT devices can be used to provide real-time data to systems like MES and SCADA, allowing for improved process monitoring and control. Additionally, IoT data can be used in production planning and enterprise business planning systems to inform decision-making and improve overall efficiency.

Overall, the integration of IoT devices into the Purdue model can enable better real-time monitoring and control of industrial processes, leading to improved efficiency, productivity, and cost savings.
