About this Manual
This manual contains the following chapters:
• Introduction (this chapter)—Introduces the WebGPI and WebGPI-Log applications.
• WebGPI Application describes this application’s windows and their controls and
indicators.
• WebGPI-Log Application describes this application’s windows and their controls and
indicators.
• How to Use the WebGPI Application has step-by-step instructions for performing
common WebGPI application tasks.
• How to Use the WebGPI-Log Application has step-by-step instructions to log data at
higher rates than can be achieved using the WebGPI application’s logging function.
• PC and Cabling Requirements details PC and cabling requirements.
About the WebGPI and Web-GPI-Log Applications
The WebGPI application is a browser-based (Web), general-purpose interface (GPI)
software tool for servicing Sauer-Danfoss microcontrollers.
You can use the WebGPI application to:
• Download default tuning values, applications, and kernels (operating systems) to
microcontrollers.
• Upload tuning values from microcontroller applications and create default tuning
value files containing these values.
• View and change microcontroller application values.
• Log and plot microcontroller application values.
• Troubleshoot and debug microcontroller applications.
The WebGPI-Log application is a high-speed data-logging tool. The WebGPI-Log
application data acquisition rates are typically twice as fast as the WebGPI application
rates The WebGPI-Log application installs along with the WebGPI application.

Debug Mode Pane
This pane allows you to view microcontroller inputs and directly set microcontroller
outputs when the WebGPI application is in the debug mode.
Clicking IO Test puts the WebGPI application in a troubleshooting debug mode that
bypasses the microcontroller application. To enter the debug mode, you must connect to
the microcontroller without opening the microcontroller application interface.
The debug mode directly applies output values. It bypasses fault and limit protections.
Changing outputs can cause sudden and unexpected machinery movements that can
result in personal injury and equipment damage.
Understand the consequences of changing microcontroller outputs. Be prepared for sudden
