4.15.2 Application

The SCALER point allows the user to perform simple math functions such as conversion

of units. The SCALER point takes the value from user specified database references,

multiplies each by a constant and adds the three product terms. A constant K may also

be factored in. The SCALER point works in conjunction with parameters that are in

floating point format.

RefValue1

RefValue2

RefValue3

RefValue1 - 3 are the values of the PntRef1 - 3 parameter references.

The references can be to any point that produces a floating point value.

Value1 Value parameter converted to Integer format

PntStatus Byte value indicating status of point Values are:

0: No error

15: Invalid Type for PntRef

16 Invalid Number for PntRef

17 Invalid Param for PntRef

19: PntRef point does not exist

25: PntRef is not defined

Elapse Time the SCALER point last executed.
