: Enables WinCC to actively send REST requests to external systems, triggered by tag changes or alarms. Technical Details
The WinCC REST API does use API keys or OAuth2 by default. It relies on Windows Integrated Authentication (Negotiate/NTLM) or Basic Auth (over HTTPS only for security).
Streaming SCADA data to analytical tools (e.g., Python scripts) to predict maintenance needs or optimize energy consumption. wincc rest api
Querying archive tags and process data for reporting or analysis.
A data scientist trains a model in Azure Machine Learning. : Enables WinCC to actively send REST requests

For WinCC Professional, enable the REST service option in Runtime general settings, set the hostname to appropriate value (e.g., "localhost" for testing), configure the port, and activate the REST Service in the Services tab. The Windows service "CCRestService" should appear as active when properly configured. Streaming SCADA data to analytical tools (e
The REST API typically communicates over port 80 (HTTP) or 443 (HTTPS). Ensure that your Windows Firewall on the WinCC server explicitly allows inbound traffic on the designated port for the IP addresses of your client applications. Programmatic Implementation: Python Example
