Hello,
In I/O Engineering 3.6 only a short list of IDN's appear when you try to add expert process data:
If you reinstall the Device Description xml's for ctrlX DRIVE it fixes the problem. (The Dictionary xml's contain the IDN list. They can't be installed directly, but the main xml for each drive type that pulls in the dictionary)
After doing this, any drives you add subsequently should show the entire list of IDN’s to select for Expert Process Data. For any drives you previously added you would have to right click and select Update Device to apply the change.
Best regards,
Brian
