CREATE A PRACTICE FOR USING PROFINET COMMUNICATIONS NETWORK FOR EDUCATIONAL PURPOSES

Abstract

Profinet industrial communication network was used by most of the factories to manage and control production lines. Building a practice model of Profinet communication network for educational purposes is essential and important to meet the needs in the industry. The paper presents the problem of building research, designing, programming and manufacturing a practical model of Profinet communication network. Practice model with practice from basic to advanced: The first is programming the communication network between devices: PLC S7-1200 (PLC Server), PLC S7-1200 (PLC Client 1), S7-1200 (PLC Client 2), inverter G120C - HMI KTP700 PN; the second is to perform the problems of controlling the conveyor speed using PID controller. The results are evaluated by running the model experiment, directly observed on the HMI, showing that the system works well with data between PLCs transferred quickly and accurately, the actual speed of the conveyor belt adheres well compared to set speed.
