Performance Analysis of Profinet Network in PLC-Based Automation System

Industry 4.0 will be a new industrial revolution that will have a profound effect on the international industry. This industrial revolution is marked by the use of the Cyber Physical System (CPS) and the Internet of Things (IoT) where the equipment in the manufacturing process will change to become a Cyber Physical Production System (CPPS). The main key in the concept of CPPS and IoT is the speed in exchanging data between devices so that data can be obtained in real time. In this study, the authors experimented to find out the performance of traditional soft PLC and PLC (hard PLC). Build simulations by designing an HMI that will exchange data with a PLC. In this research, HMI is made different for each packet data capture, so there are 18 pages of HMI created to experiment with different types of controllers, variations in the number of tags and variations in the acquisition cycle settings. The data obtained from the measurement results are used to analyze the response time between the HMI and the controller used. These results indicate that the performance of exchanging data between devices using soft PLC as a controller 19 times faster than the hard PLC and more stable when adding the number of tags on the HMI system. So it is possible to use soft PLC as a controller instead of conventional PLC or hard PLC. Using a PC as a controller will make it easier to connect to a wider network so that it can help in the application of CPPS and the IoT.
