Linearization

Linearization can be used to convert analog values from I/Os into decimal or other integer

values. An analog value from a temperature probe, for example can be converted to

degrees Celsius and displayed on the controller's display screen.

Linearize values for Display

Note that the linearized value created in this way may be displayed-- but the value cannot

be used anywhere else within the project for further calculations or operations.

You can enter an Analog value, such as temperature, via the M90 keypad, then convert

that value into a Digital value for comparison with a digital value from a temperature probe

by selecting Enable Linearization in the linked Variable.

This conversion process is Reverse Linearization.

To enable Analog to Digital conversion:

1. Create a Display for entering the analog value.

2. Create an Integer Variable.

3. Select keypad entry and enable linearization.

4. Enter the linearization values for the x and y axes.
