Linear

This Conversion type applies to a VoltageInputPoint, ResistiveInputPoint, and VoltageOutputWritable points used with a linear-acting device.

For these points, you typically want the point’s output value in some units other than Device Facets (voltage or resistance). The Linear selection provides two fields to make the transition:

  • Scale: Determines linear response slope.
  • Offset: Offset used in output calculation.

For related details, see “Scale and offset calculation (linear)”.

 
NOTE: For a VoltageInputPoint used for a 4-to-20mA sensor (shunt resistor on UI input), another primary conversion type should be used: 500 Ohm Shunt, with Linear selected as the “secondary” conversion.
