18. AR Function Block
The Arithmetic (AR) block switches two main inputs of different measurement ranges seamlessly and
combines the result with three auxiliary inputs through the selected compensation function (10 types) to
calculate the output.
18.1 AR Function Block Schematic
The diagram below shows the Arithmetic block schematic.

The Arithmetic block is divided into three sections:
• Input section: Makes a go/no-go decision on the use of an input value, switches the range, and determines
the PV status.
• Computation section: Makes calculations through ARITH_TYPE.
• Output section: Applies gain multiplication and bias addition to the calculated result to perform limitation
processing for output.
* The range extension function compensates the IN and IN_LO input values when two devices with different ranges are connected, to
make smooth input switching.
