Scaling as per parameter example:
0 °C  20 % Input variable Output variable
50 °C  100 %
Function description
The Scaling function allows conversion of analogue values from sources selected by the user
(sensors, functions, network inputs, etc.):
▪ Conversion of the function quantity
▪ Scaling of the input variables = matching the value to a new reference range
▪ Limitation of the output variables by means of minimum and/or maximum thresholds
Input variables
Enable
General enabling of the function (digital value ON/OFF)
Result (enable = off)
Analogue value for the output variable when Enable is OFF
Input variable
Analogue values to which scaling is to be applied
Result minimum
Minimum value of the output variables
Result maximum
Maximum value of the output variables
➢ The minimum and maximum output thresholds will limit the value of the output variables
even if the scaling would have produced a lower or higher value.
➢ If the Scaling function is blocked (Enable = Off), it issues a value which is either defined by
the user with Result (enable = off) or which comes from a specific source.
➢ The Result (enable = off) value will not be limited by the maximum and minimum
thresholds.
