Abstract:
Nowadays, the application of Programmable logic controller (PLC) is widely known and used in this digital world. PLC’s application is obviously applied at the industrial sector. Normally, the PLC’s that have been used at the industrial field is usually to control a mechanical movement either of the machine or heavy machine in order to create an efficient production and accurate signal processing. In this project, a discussion about PLC application will be explained in more details. Whereby, the aim of this project is to install a new Automated batching system using PLC [SIEMENS (step_7)], which acts as the heart of the system. The operations system sequence is designed by ladder diagram and the programmed by using (SIMATIC STEP 7 v5.4 + sp3) software, and for supervisory control and data Acquisition (SCADA) by using SIMATIC WinCC v5.1. Limit switches is widely used in daily activities such as position detection and other purposes. In this project, limit switches is used to detect the position of the automatic valves. There is four control valves in this project, which is used to control the fluids flow, three pumps to deliver the fluids inward and outward the mixer tank and Agitator to make the mixer tank blending for a given time. Besides that, the electronics and electric devices that usually been controlled by the PLC are like indicator light and the others devices.
