Hi Maverick,
PSS9000 is an I/O rack and card system that we develop, manufacture and use at SSAB Oxelösund. The rack and card objects with their IO methods are specifically designed for this system and can't be used for any other system. If you want to use any other cards, there is a description in Guide to IO System on how to create card and rack classes, and write IO methods.
