The future of the programmable controllers relies not only on the continuation of the new product developments but also on the integration of the PLCs with other control and factory management equipment PLCs are incorporated through network into computer integration Manufacturing (CIM) system,Combining their power and resources with numerical controls, robots,CAD and CAM systems,personal computer based systems and hierarchical computer based system. There is no doubt that programmable controller will play a substantial role in the factory of the future.
Programmable controllers new advance technology includes features such as better operate interfaces,graphic user interface (GUIs) and more human oriented man and machine interfaces (such as voice modules) they also includes the development of interfaces that allow communication with the equipment, hardware, software that supports artificial intelligence,such as fuzzy logic i and o systems.
Software advances provide better connection between different equipment,using communication standards through widely used networks. New PLC instructions are developed out of the need to add intelligence to a controller, knowledge based on process learning type instruction may be introduced to enhance the capabilities of a system.The user;s concept of the Flexible Manufacturing System (FMS) would determine the control philosophy of the future.The future would almost certainly continue to cost programmable controllers as an important player in the oil industry and factory.
Control strategies will be distributed with intelligence instead of being centralized.Super PLC would be used in plant automation and other applications requiring complex,calculation, network communication,supervision of smaller PLCs and machines controllers..
