APPLICATION OF PLC AND HMI TECHNOLOGIES IN DEVELOPING A PRACTICAL TRAINING DEVICE FOR INVESTIGATING INDUSTRIAL SENSOR PARAMETERS

In the context of increasing demands for the quality of engineer training in the field of automatic control, the development of modern-standard practical training devices is essential. This paper presents the design and fabrication process of a practical model that enables students to examine key technical parameters of industrial sensors, including sensing distance, sensing area, and response frequency. The system is built based on the integration of Mitsubishi PLC control technology, an HMI monitoring interface, and a servo motor to precisely control and collect survey data. Experimental results show that the system provides high accuracy and stability, making it well-suited for teaching and research purposes in the Department of Electrical and Electronic Engineering at Hung Yen University of Technology and Education.
