11.6.2 Analogue Multiplexer [620]
The Analog Mux compares two configurable analogue input
signals (InA and InB) and generates a virtual analogue
output. Output behavior depends on the configured
operator. Output can be used as source for analogue output
or input value to analogue comparators.
Since both input and output is limited to range -100% to
100% some operations might overflow. Result is always
limited within the range. Consequently some operators have
a "divided by 2" variant to always produce overflow safe
variants (result is always within the range).
AnMux1 [621]
AnMux InA [6211]
First input to the AnMux1. Select one of AnIn1 - 4. Input
numbered as [6111], i.e. AnIn1 = 16 and default is AnIn1.
AnMux InB [6212]
Second input to AnMux1. Select one of AnIn1 - 4. Input
numbered as [6111], i.e. AnIn1 = 16 and default is AnIn2.
Operator [6213]
Operator of the Analogue Mux 1. The names shown on the
control panel will be changed according to the following.
AnMux2 [622]
The same function as in Analog Mux1[621].
AnMux InA [6221]
The function is the same as in Analogue Mux InA value
[6211].
AnMux InB [6222]
The function is the same as in Analogue Mux InB value
[6212].
Operator [6223]
The function is the same as in Operator [6213].
