Wincc Rest Api May 2026

WinCC REST API

The (and the related REST Connector ) is a modern interface introduced primarily in WinCC V8.0 and WinCC Unified to bridge the gap between industrial OT (Operational Technology) and standard IT environments. It allows external applications to interact with SCADA data using standard web protocols like HTTP and JSON. Core Functionality WinCC handles REST in two distinct ways:

• Endpoint: PUT /api/v1/tags/tagName
• Note: Writing usually requires higher privileges (Operator vs. Observer role).

A Python script runs on an edge device. It queries historical vibration data from WinCC via GET /api/history . The script trains a simple statistical model. When the model predicts failure > 80%, the script writes an alert back to WinCC using POST /api/alerts/custom . wincc rest api
