DISTANCE
2.6.4. Input Scaling
2.6.4.1.
Defines the operational lower range value of the input value (Process Value
Scale) in PV (volume/level) Units. Process Value Scale normalizes the input
value to a customer-defined range.
Values
2.6.4.2.
Defines the operational upper range value of the input value (Process
Value Scale) in PV (volume/level) Units. Process Value Scale normalizes
the input value to a customer-defined range.
Values
