Design of Liquid Level Control System Based on PLC

A Programming Logic Controller is a digital computer used for automation of the electromechanical process. It is used to convert the previously used relay logic or wired logic for automation of an industrial process into ladder logic. It is used automate respective process but in this project RS-logicx1600 is used which is in the cheapest category or entry level of PLC. This paper deals with Design of Liquid Level Control System Using Programmable Logic Controller. Currently Textile Factory is used conventional relay control system to control level of fluid, however there are a lot of limitations , such as wastage , large no of labours, and difficult to maintained . In order to minimize those problems, we have tried to make Automatic using PLC. Electronic device used in my project are as sensor - switch, level sensor (limit switches), as controller:-PLC and pump motor, solenoid valve. Having the above device, I have also programmed using Ladder logic diagram In RS-logicx1600 Software and stimulate in order to load to PLC.
