5.5.8 Scaling
5.5.8.1 Scaled Input
To modify the values that the operator enters in the operating device in
line with the values used in the connected controller, inverse scaling
must be carried out.
The system uses the following formula to scale the input:
Fig. 5-19: Scaling of the input variables in the operating device
A rounding error may occur during scaling which is calculated using the
following formula.

5.5.8.2 Scaled Output
You can scale output to modify the range of values to suit user inter-
face requirements. The scaling data is used for both output and input in
the operating device. This does not restrict the range of values for the
variable. Scaling is only carried out in the operating device.
You use the following operands for scaling:
–Factor,
–Divisor and
– Addend.
