7.4.5 Median Value
The Median value funtion supplies the arithmetical median value of
the input values over an adjustable time range.
The time range is set in seconds with the Time parameter.
The formation of the median value is accomplished by means of the
"Repeating Average" procedure. This means that, when the time
setting is "2 seconds", for example, the input values are compiled for
2 seconds, then averaged and output at the output. The next median
value interval begins afterwards. The median value remains stopped
at the last median value thereby
Inputs x: Input value (Numerical)
Outputs: y: Median value (Numerical)
Parameters: p
1
: Time (Numerical)
7.4.6 Note Value
The Note value function is used to hold on to certain values (to
freeze them). It has one numerical and one Boolean input.
If the Boolean input value is "1", then the numerical input value is
output at the output. If the Boolean input value is "0", then the last
output value remains in effect.
If the value is only to be applied for one flank of the Boolean input,
then you can put the function Pulse generation upstream from it (see
Chap. 7.8.6).
Inputs x
1
: Input value (Numerical)
x
2
: Switch value through (Boolean)
Outputs: y: (Numerical)
Parameters: -
7.4.7 Note Minimum
The Note minimum function supplies as the output value the
smallest value that the input value has yet reached.
If the input value is greater than the output value, then the output
value remains unchanged. If the input value is less, then the output
value will be reset.
The minimum can be reset with the Boolean input x
2
. The input
value wil be applied directly at the output for as long as this input is
"1".
Inputs x
1
: Input value (Numerical)
x
2
: Reset (Boolean)
Outputs: y: (Numerical)
Parameters: -
