The variable selector functions are always active even if the source and destination are not routed to valid parameters. If a source is not a valid parameter then the source value is taken as 0. The
update rate for each of the variable selector functions is always 4ms.
The following description is for variable selector 1, but variable selector 2 operates in the same way. The source parameters selected with VariableSelector1Source1 (12.008) and
VariableSelector1Source2 (12.009) are converted to a percentage value, scaled with VariableSelector1Source1Scaling (12.013) and VariableSelector1Source2Scaling (12.014) respectively
and then combined with a function defined by VariableSelector1Mode (12.010) to give VariableSelector1Output (12.012) as a percentage value. If VariableSelector1Enable (12.016) = 1 then
the function operates normally. If VariableSelector1Enable (12.016) = 0 then VariableSelector1Output (12.012) = 0.00% and any states within the function are reset (i.e. the time constant function
accumulator is held at zero). If the value of VariableSelector1Mode (12.010) is changed then all internal function state are also reset.
The table below shows the functions that can be selected with VariableSelector1Mode (12.010).
