Standard Mode
The operating device uses the following formula to scale the output:
Fig. 5-23: Scaling of the output variables in the operating device
Use the following formula to determine the operands.
Fig. 5-24: Scaling of the output variables
The following example will help you determine the operands.
Example: Range of values for output values:
Lower limit for output value = 0
Upper limit for output value = 100
Current value in operating device = x
Range of values for controller values:
Lower limit for controller values = -4096
Upper limit for controller values = 4096
Current controller value = y
Operand Range of Values
Factor –32768 to –1, +1 to +32767
Divisor +1 to +32767
Addend –32768 to +32767
