Accessing TIA Portal’s PLC tags using Node-RED

The Industrial Internet of Things (IIoT) has revolutionized how industrial systems and devices are connected and controlled. In the Siemens industrial environment, where efficiency and seamless integration are paramount, Node-RED has emerged as a powerful tool for IIoT applications. Node-RED provides a visual programming interface that simplifies the development of IIoT solutions by allowing engineers to connect and automate devices and services through a flow-based approach. By leveraging Node-RED's capabilities, engineers can easily interface with Siemens PLCs and access tags to collect real-time data, perform analytics, and enable automation in the industrial ecosystem.
