All complex functions in modern industrial processes depend upon SCADA and DCS to fulfil their requirements. Typical domains include electric power grids, oil refineries, pharmaceuticals, water management systems etc.

As we move towards creating infrastructure that requires high performing monitoring and analytics, we face new challenges. Especially now with the arrival of IoT, where networked embedded devices are integrated in most industrial domains, the need of the hour might be to integrate large scale System of Systems (SoS). And this is where our next generation of SCADA / DCS system of systems will come into play.

With each generation, the architecture of SCADA systems has shifted. From monolithic systems, to distributed systems, to open system architecture and open protocols – the next generation will move from utilising single controlling authority, to components that are developed and evolve independently.

Modern enterprises need to be agile and dynamically support decision making processes at several levels. For this to work out, critical information needs to be available at the right

place in a timely manner at several levels. Hence we need to move from an information driven network to a communication impelled network. Information will need to be processed at local loops and explicitly propagated.

The next generation SCADA/DCS systems will have to cope with a much higher amount of diverse distributed data and information in real-time and make decisions based on cooperation with internal and external data and information acquired and exposed as “services”. The HMI will no longer be attached to a static location, but will have to offer “anywhere, anytime, and any device” type of functionality.
