Abstract—By improvement of industries, the demand of using of feasible industrial control system (ICS) and optimizing the current method is growing. Distributed control system is one of the best and usual methods for controlling an industrial system. Simplicity, flexibility, extensibility, scalability, fault tolerance and accommodation are some of its features that caused this method outshine from the other methods and by using new technologies, new facilities can be added easily. Nowadays Information Technology (IT) science gives us various tools for optimization and better execution of DCS. This paper will introduce these tools and their usage and at the end a practical example including all of these tools will be presented.
