Wincc Rest Api

To begin using the WinCC REST API, the "Web Runtime" or "Connectivity Pack" usually needs to be enabled and configured within the WinCC project. Once the endpoint is active, developers can use tools like Postman to test requests. A typical GET request to retrieve a tag value involves calling a specific URL endpoint and receiving a JSON payload in return. This JSON format is lightweight and easy to parse, making it ideal for high-performance applications. Future-Proofing Your SCADA System
