PLC Based sequential batch process control system

ABSTRACT

Programmable logic controllers are extensively used in industries for controlling sequence of actions of the process. The sequence of process flow is decided for controlling the parameters like level and temperature. The brain of the system is PLC .Appropriate hardware for interfacing the process to the controller is developed for controlling the level ant temperature of the process. For controlling sequence of actions ladder diagram is developed .
Programmable Logic Controller (PLC) is designed to operate in real time environment. It has been observed that in many industries distributed control system and PLCs are extensively used. PLC based sequential batch process control (PLCSBC) is a laboratory type setup. This setup will be useful for demonstrating the use of PLC in sequential control operations in industry and development of ladder diagram for particular application. The system under consideration is designed to carry out sequence of events. The process under consideration is Batch process, whish is controlled by PLC.
