Evaluation of Data Transfer from PLC to Cloud Platforms-Based Real-Time Monitoring Using the Industrial Internet of Things

Abstract:

The industrial internet of things (IIoT) is progressing owing to intervention as technology of Industry 4.0, which requires devices to be connected to the Internet in industrial systems. These are based on the efficient management and monitoring of data using a network between PLC S7-1200 and Simatic IoT2040, through an IIoT, which stores, processes, and transfers data within the Freeboard web platform. However, an important aspect is to compare the response time of processed data between a real-time mechatronic task and interface IIoT. The system used is OPC-UA for the transmission and reception of data from the devices used in the production, the IoT tool Node-Red in the gateway-connected OPC-UA client and Freeboard web platform, permitting the analysis and visualization of data in real time, guaranteeing greater assertiveness in decision-making. The average communication delay time from the production line to the Cloud ranges from 2 ms to about 10 ms.
