Why can't I find the BMXDRC0805 module in my Unity M580 configuration?

Issue
Do not see the BMXDRC0805 IO module as a selection with M580.

Product line
Unity Pro, Control Expert, Modicon M580, Modicon X80 IO.

Resolution
This module was not added to Unity for M580 until v13.0 with the UnityPro_HF_ DRC0805 Hotfix. Previous versions of Unity do not support this combination.
