Function blocks
Transducer Block (TB)
The Transducer Block "
Analog Input (AI)
" takes the original measured value (Secondary Value 2),
carries out the min./max. adjustment (Secondary Value 1), carries out a linearization (Primary Value)
and makes the values on its output available for further function blocks.
