The output from the Level Transducer Block can be called the Primary Value (or
Secondary Value). When it becomes the input to the AIFB, it is called the
Process Variable.

Programming

SITRANS LR 460 carries out its level measurement function according to the set of built-in
parameter tables. You can make parameter changes via the Siemens Milltronics
handheld programmer, a PC running SIMATIC PDM or a HART handheld communicator.
