The use of control system or computers to run and direct industrial process and industrial machinery is called industrial automation or numerical automation. In the system, human labor is replaced by sophisticated computers. Industrial automation is different from mechanization, for in mechanization human operators run the machinery as per the requirements of the work. But in industrial automation most of the works are facilitated by the highly improved computers. The whole system and the processes of the industry are automated under the automated system of Industrial Computing. Industrial automation has a wide variety of application in the today’s economic world. The industrial automation is playing a very important role in the maximizing the efficiency of industries. They create a complex system of human computer interface to facilitate a wide range of applications.
Today industrial automation is as well used in banks through Smart Cards and Bonus Cards, hospitals and other different industries. Industrial automation requires several automation tools that make this type of systems to be possible. These tools include Distributed control system like industrial computers and embedded computers as well as different programs for different functions, human machine interface, laboratory information management system, manufacturing executive system. In addition to it in manufacturing units some other tools applied are programmable logic controller, programmable automation controller, supervisory control and data acquisition, and simulation and field bus.
