Basics of HART Communication Protocol Check out the full blog post over at https://realpars.com/hart-protocol/ With HART, we can send analog data, the measured value of the process variable, along with digitally-transmitted data, such as a tagname, or calibration settings, or sensor diagnostics. This would be a real productivity enhancement for the process plant! HART-enabled sensors require only a single pair of wires for communication; so, to upgrade an existing non-HART sensor loop to a HART-
