Nowadays, the use of automation systems is increasing and the basis of these automation systems is often appliances based on the Planned Logical Controller (PLC). PLC is used for automation purposes in the industry with many advanced machines and devices. Used in industrial automation systems together with PLC, the Supervisory Control and Data Acquisition SCADA (Supervisory Control and Data Acquisition SCADA), human-Machine Interface HMI (Human-Machine Interface HMI) systems ensure that human errors and interference are produced safely, with quality and fast. Through these systems used by industries, developed automation software allows high quality and low-cost serial production by working 24/7. Large enterprises prefer to use automation systems to minimize human power and errors, prevent work accidents, reduce costs, and make quality and fast production. PLCs are widely used especially in the food, chemical tyres, automotive sectors in packaging packaging systems, cement factories, ventilation and cooling facilities, textile factories. These systems are widely used in the industries, preferred because of their simple programming structure, installation, use and installation ease, sustainable working in difficult working environments, not causing too much failure, less maintenance demand, and low energy consumption. In the article study, the areas that are applied by studying PLC-based automation systems were addressed. Also a sample study is presented that makes the work of Mill machines located in the truck tyres manufacturing factory safe using PLC and HMI. These machines are added entrance and exit cards to ensure safety automatically. This work has resulted in the reduction of the risk of employment accidents by making the production fast and quality. In addition, thanks to the developed HMI interface, the control and tracking of the defects and safety conditions in the machines can be carried out without the need for additional maintenance staff.

In recent years, the use of automation systems has been increasing, and the basis of these automation systems is generally Programmable Logic Controller (PLC) based application. PLC is used for automation in the industry where there are many advanced machines and devices. In industrial automation systems, it is also used Supervisory Control and Data Acquisition (SCADA), Human - Machine Interface (HMI) systems to ensure safe, quality, and fast production by minimizing human errors and intervention. Because of these systems used in the industries, the automation software developed enables 24/7 production with high quality and low cost. Large-scale companies prefer to use automation systems in order to minimize worker labor and error, prevent work accidents, reduce costs, and make high quality and fast production. PLCs are widely used in packaging systems, especially in the food, chemical, tire, automotive industries, as well as in cement plants, ventilation and cooling facilities, and textile factories. These systems, which are widely used in industries, are preferred due to simple programming structure, ease of setup, use and assembly, durable operation in difficult working environments, low failure, low maintenance cost, and low energy consumption. This article presents the usage and application areas of PLC based automation systems. In addition, a case study is presented that Mill machines, commonly found in truck tire manufacturing factories, are secured using PLC and HMI. Input and output cards have been added to these machines to provide security automatically. As a result of the case study, the production is made faster and with higher quality, and employees are provided with a safer environment. In addition, thanks to the developed HMI interface, Mill machines are able to control and monitor malfunctions and safety situations without the need for additional maintenance personnel.
