Linearization, Vector Linearization

The Linearization functions, located on the Math menu, enable you to convert values. Use them, for example, to convert analog input values to a values in degrees Celsius.

This function linearizes a single source value, then stores it in the target register.

If, for example, X1 and Y1 are 0, and X2=1023 while Y2=1000, the output value will be linearized as graphed.

These values would cause:

An input of 5.0V to be converted to a digital value of 500.
A input of 10.0Vto be converted to a digital value of 1000.

This function linearizes a vector of source values, then stores the values in the target vector.

With the exception of Constant Value, any of these operands may be used to contain the output value.

Note ♦

Analog output values are contained in the register that you link to the output in Hardware Configuration.

Working within the 4-20mA range

Analog values can be converted to physical values, for example Engineering Units (EU) such as degrees Celsius, by using the Linearization FB.

Analog output values are contained in the register that you link to the output in Hardware Configuration.
