PROFINET 기반 I/O 통합 실시간 Edge Gateway 개발. (Korean)

Development of the PROFINET based I/O Integrated Real-Time Edge Gateway. (English)

As the importance of smart factories has recently been emphasized in industrial settings, the use of industrial networks is increasing. Accordingly, research was conducted on Edge Gateway, which collects data generated from equipment at industrial sites and transmits it to a cloud server. However, Edge Gateway studies require additional I/O to be installed in the industrial network to receive status information generated from manufacturing devices. This may result in increased network communication cycles and modification of PLC programs, which can result in budget and time consumption. Accordingly, in this paper, the solution is to add I/O to the Edge Gateway device to minimize PLC program modification without installing additional I/O in the industrial network. According to the experimental results, adding distributed I/O to the network resulted in an increase in cycle time of up to 0.24ms in the communication cycle, and showed an increase in cycle time of up to 8.41%.
