IODD Viewer


The IODD Viewer is a tool to display IO Device Descriptions (IODDs) in a human-readable way. This
view can be saved into an HTML file or printed. The Viewer does not only consider the main XML file,
but the complete set of files that make up an IODD, i.e. also the external language files and the
graphics files. It opens an IODD that exists as individual files on disk, but in addition, it also directly
opens an IODD whose files are packed into a ZIP file, which is the recommended release format.


You will find the IODD Viewer on the IO-Link web site:
