  • 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.
