Abstract
Programmable Logic Controller (PLG) is extensively used in industries for controlling sequence of actions of the process since last two decades. Hence we have decided to develop PLC based sequential batch process control system of our laboratory. 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 and temperature of the process. For controlling sequence of actions ladder diagram is developed. The program minimizes shut down by providing recycle under certain condition to establish normal operation before checking out. Timer provides precise timings. Finally this system is factory programmable.
