TEDS (aka Smart Sensors) have a digital interface for calibration and configuration information AND (maybe? I haven't read through the above link and don't use these at work) an analog output.
Smart Sensors gathered a lot of interest a few years back but don't seem to have caught on. I don't believe that the FRC cRIO can easily and fully support Smart Sensors. Specifically, the digital cal/config interface has not been developed and we don't use the standard connector.
