IODD Checker
IO-Link
Description:
The IO Device Description (IODD) describes the functionality of a device from the IO-Link point of view.
The IODD Checker is able to check the content of IODD files for IO-Link. It checks the accuracy of the IODD according to the IODD schema and the test specification and stamps the IODD in case of no errors. This helps to build a valid description file and insures interoperability. IODDs are only accepted from IO-Link Engineering Tools when they are checked and stamped with a valid version of this IODD Checker.
