SINAMICS S120 Web Server – User-Defined Monitoring Pages
This application example shows how to extend the integrated SINAMICS S120 web server with user-defined pages to visualize drive data, diagnostics, and communication information using a standard TCP/IP browser connection.
The approach enables customized monitoring dashboards without requiring additional SCADA software.
Application Overview
The solution allows key operational data of the drive to be displayed through customized web pages, including:
- Enable signals, speed, torque, and parameter values
- Digital input/output states of the control unit
- Control and status word information
- Network configuration and communication telegrams SINAMICS S120 web server-User d…
Displayed values are refreshed cyclically to visualize real-time status changes.
System Concept
The architecture connects a PC (engineering station or browser client) to the SINAMICS S120 control unit via TCP/IP, allowing direct access to diagnostics and visualization without additional software layers.
This provides a lightweight, web-based interface for commissioning and service tasks.
Example Web Pages Included
The sample project provides several ready-made monitoring pages:
📄 Documentation Page
Displays manuals and documents stored directly in the drive and allows downloading them locally.
🌐 Network Page
Shows configuration of PROFINET and Ethernet interfaces, including IP and connection data.
⚙️ Status CU Page
Visualizes control and status words of the control unit using color-coded indicators for quick diagnostics.
🔴 / 🔵 Axis Pages
Provide diagnostics for each axis, including enable signals, speed, torque visualization, and alarm states.
🔌 Status I/O Page
Displays digital inputs and outputs with live signal indication.
📡 Communication Page
Shows cyclic telegram data (PZD values) exchanged between controller and drive.
⚙️ Configuration Page
Allows functions such as synchronizing system time or restoring factory settings (administrator access required).
Engineering Workflow
Implementation involves:
1️⃣ Uploading prepared web files to the SINAMICS CF card or web server directory.
2️⃣ Creating a structured folder system (configuration, scripts, images, etc.).
3️⃣ Activating the pages through the web server “User’s Area” settings.
4️⃣ Accessing the customized interface through the drive’s IP address using a browser.
This enables commissioning and diagnostics directly from a web interface.
Key Benefits
✔ Web-based diagnostics without SCADA installation
✔ Faster service and troubleshooting access
✔ Customizable visualization tailored to machine needs
✔ Direct monitoring of communication and drive states
✔ Reduced engineering overhead for simple visualization tasks
Typical Use Cases
This solution is ideal for:
- Digital service concepts and condition monitoring
- Machine builders needing lightweight visualization
- Commissioning engineers performing quick diagnostics
- Maintenance teams requiring remote drive access
- Retrofit projects adding monitoring without redesign
