Viewer Variables
System Viewer Variables
Viewer Variables, also known as Dynamic Filtering, enable data-driven content management in PADS4. This feature allows you to create a single presentation that dynamically adjusts for multiple Viewers based on predefined values.
For a detailed example of how to use Viewer Variables, refer to the Viewer Variables Introduction Page.
System Viewer Variables
In addition to custom Viewer Variables, PADS4 provides System Viewer Variables at runtime. These built-in variables allow you to access essential system information dynamically.
Available System Viewer Variables
| Viewer Variable Name | Description |
|---|---|
| viewername | The identification name of the Viewer. |
| monitorname | Same as viewername. Used in older PADS versions for backward compatibility. |
| pads4serverurl | Displays the URL of the PADS4 Server, formatted as:HTTP(s)://server/hostpath |
How System Viewer Variables Work
- Automatic Updates – System Viewer Variables are generated by PADS4 at runtime and always reflect the current Viewer state.
- Use in Presentations – You can include them in text fields, data providers, or other dynamic content elements.
- Compatibility – These variables ensure seamless integration between different PADS4 versions.
Conclusion
System Viewer Variables provide essential information about the Viewer and PADS4 Server without requiring manual input. They simplify content customization and automation, making PADS4 a more efficient digital signage solution.
