In order to bring automation in industrial manufacturing system, SCADA has been used. Using SCADA is not a new thing, as this system has been there for a long time. However, on its voyage as an effective industrial automation system, it has undergone a lot of changes. With the advent of time, a lot of things have evolved. Today, SCADA stands more robust, elegant and accurate than earlier. But, that does not mean we should limit our knowledge in WEB SCADA on the latest generation of this system. We need to know its previous architectural models too as that will help us to understand a few basics of SCADA architectural models.
1. Monolithic – First Generation
The first generation architectural model of HMI SCADA was done by minicomputers. When SCADA was introduced, there was no common network service. As a result, SCADA system used to be independent systems, having no relationships with others. At the first generation system, there were ample of occasions, when redundancy was encountered. Well, that was quite common, as the system did not have robust hardware support that is available at today’s time.
2. Distributed – Second Generation
The second generation system has been termed as ‘Distributed’ system. This is the first time information can be distributed over LAN (Local Area Network). SCADA computers can be connected and information can be shared to achieve better results. This was one step up towards complete business process automation that we see today.
3. Networked – Third Generation
The third generation of WEB SCADA has been named as networked. From LAN connection, this architectural model evolved to a better and more reliable network connection.
4. Internet of Things – Fourth Generation
With the advent of technology and with the introduction of seamless hardware components, fourth generation of SCADA is shaping up, and it has been named as Internet of Things.
