Specify scaling factors

A scaling factor is a number that indicates the extent of scaling that can be used. For example, the scaling factor value 0.8 specifies that you can use 80% scaling. The value 1 for a scaling factor indicates that scaling is not used. You cannot use the scaling factors for the string data type.

Scaling factors are required when different equipments use different inputs to produce the same result. For example, pumps A and B are used for transferring water. If pump A takes input values in liters per minute and pump B takes input values in gallons per minute, you must use the appropriate scaling factors for each pump.

You can configure the following scaling factors for a selected specification in the Scaling section.

Scaling Factor DB to IO

Used during download of specification properties. The working attributes are multiplied with this scaling factor before target attributes are updated.

Scaling Factor IO to DB

Used during upload of object values. The target attributes are multiplied with this scaling factor and are written to working attributes of a specification.

Specify the value for a scaling factor

• In the Value or Input Source box corresponding to a scaling factor, type the value or provide a reference.
