Scale
This function block allows to scale a word (16 Bit) value or a double word (32 Bit) value provided as two words.
Calculation rule: Out = (In * X Scale) / Y Scale
If the calculated result is > 65535 the output will be limited to 65535. If the results is < 0 the output is limited to 0. If a word
should be scaled it has to be connected to "In Low Word". The "In High Word" input can be left open in this case (internally set
to 0).
For an example see section "DX1xx Output".
