Interoperabilidade entre controladores industriais, sistema de monitoramento web e armazenamento de dados

Abstract

This industrial automation project aims to develop a liquid level control system using Ladder programming in TIA Portal and process simulation in Factory I/O. Additionally, the project integrates communication via OPC UA, enabling real-time data supervision and information storage for further analysis. Ladder programming, one of the most widely used languages in industrial automation, serves as the foundation for implementing the control logic in TIA Portal. After programming the PLC, the next step is to simulate the system in Factory I/O, where tanks, sensors, and actuators are modeled to interact according to the defined logic. To ensure efficient communication between the simulated process and the supervisory system, the OPC UA (Open Platform Communications Unified Architecture) protocol was used. In this context, OPC UA acts as an intermediary, transmitting control data from TIA Portal to a monitoring environment developed in Node-RED. This communication allows the PLC to send accurate information regarding the liquid level and actuator status, enabling decision-making based on the acquired data. With integration and communication established, the final phase of the project involves developing a dashboard for data visualization and analysis. Node-RED is used for processing the acquired data, which is then stored in InfluxDB, ensuring record persistence for historical analysis. For data visualization and monitoring, Grafana is employed, allowing the creation of interactive dashboards and a detailed analysis of system behavior over time. In conclusion, this project demonstrates the feasibility and efficiency of an integrated approach to control, monitoring, and data storage. The combination of Ladder programming in TIA Portal, simulation in Factory I/O, communication via OPC UA, processing in Node-RED, storage in InfluxDB, and visualization in Grafana highlights the importance of interoperability between different technologies in industrial automation.
