If this is truly a stand-alone software application, there won't be IFUs for the hardware! Think of a software application that analyzes images. The images can come from a variety of sources as long as they meet basic criteria. The imaging equipment is not part of the system. The computer the application runs on is not part of the system (although, as I've stated, it's in the manufacturer's best interest to scope what's supported!). Software is not controlling anything. There are no sensor inputs.
