This Paper Focused on the testing device i.e. conveyor system for the quality control department using automation (PLC & SCADA). The paper belongs to the different sections such as how the conveyor system works on PLC. Second thing how the system handles the section of motors i.e. D.C. motors, solenoid etc. Third thing is the most important how it will handles the faults detected in the conveyor system and gives us the fault free output. The main goal of the project is to reduce the errors in the product size. The conveyor system also deals with the monitoring structure i.e. SCADA part of the system. SCADA gives you the visualisation structure that's makes easy to handle the system and error free output. The solenoid connects in the project will ejects the faulty material and gives you the suitable material or product.
