You effect I/O assignment for your HART instruments like with any other instruments that require I/O assignment. In the Domain Explorer, right-click the required I/O card and then select Actions > I/O Assignment. For details, see I/O Assignment.

-
When assigning "non-HART" analog instruments to HART-compatible I/O cards, the software assigns only the analog signals. (DI or DO are not allowed anyway).
-
You can assign HART instruments to conventional I/O cards (AI to HART AI, AO to HART AO), but the software assigns only the analog signals and not the virtual digital tags.
-
You can assign HART instruments to I/O cards with MIXED I/O type, but the software assigns only the analog signals and not the virtual digital tags.
