Motherbox 3

Measurement data concentrator for Web-IOs

Use the Motherbox to archive measuring data from Web-IOs and Web-Thermographs. Determine an individual logging interval for each measuring point available in the network at the frequency you want the current measuring data to be automatically polled and archived in the box-internal database of the Motherbox.



  • Network

Management and connectivity:

  • Configuration
    • Startup using WuTility (three clicks and you’re done)
    • DHCP
    • Web-based management
  • Store and visualize
    • Inventorying of Web-IOs using Web-based WuTility
    • Combine measuring values from different Web-IOs in measuring data profiles and create application-specific overviews
    • Database with measuring values from any number of Web-IOs directly in the box
    • Create Web-based visualization and control sites for Web-IOs via drag-and-drop using the Site Creator.

      You activate the video function using the following button, whereby you use the provider Google and (at your own risk in terms of data protection ;) share data with it.

Worth knowing

Processing the measurement values

By cyclically polling the Web-IOs a consolidated measurement database is created in the Motherbox. View recorded measurement data directly in the browser, access your application directly via the SQL interface for migrating the measurement data, or export them automatically via FTP.

Use the Motherbox as a visualization server. Use the integrated Site-Creator with drag-and-drop to create Web-based visualization and control pages for Web-IOs.

The internal web server also allows you to upload from your own web pages, which enables creation of web-based applications. For example you can prepare and display recorded measurement data for a specific application.
