The Purdue model, also known as the Purdue Enterprise Reference Architecture (PERA), is a reference architecture for industrial automation systems. It was developed in the late 1980s by researchers at Purdue University as a way to organize the different levels of an industrial control system into a hierarchical structure.
The Purdue model consists of five levels, each representing a different aspect of the industrial control system:
Level 0: Physical processes - This level represents the physical equipment and processes that are being controlled, such as sensors, actuators, and machinery.
Level 1: Basic control - This level includes the devices and systems that directly control the physical processes, such as programmable logic controllers (PLCs) and distributed control systems (DCSs).
Level 2: Supervisory control - This level includes the systems that monitor and control multiple processes, such as manufacturing execution systems (MES) and supervisory control and data acquisition (SCADA) systems.
Level 3: Production planning - This level includes the systems that plan and schedule production activities, such as enterprise resource planning (ERP) systems.
Level 4: Enterprise business planning - This level includes the business systems that support the overall goals and objectives of the organization, such as customer relationship management (CRM) and financial management systems.
The Purdue model provides a framework for organizing and integrating the various components of an industrial control system, from the physical processes to the enterprise-level business systems. It has been widely adopted as a reference architecture for industrial automation systems, and is used by many organizations and vendors in the industry.
SDN and NFV is the next phase of technology change which will help service provider to launch the services in single click. This is all about the programmability of the networks by using open source software defined network controller.
