Float

About​

Float variables, also known as floating-point variables, are a data type used to represent decimal numbers with a large range of values. They can be used to measure and control physical processes that require high precision. Float variables are stored in memory as a combination of a sign bit, an exponent, and a mantissa, which allows them to represent very small and very large numbers with high accuracy. They are commonly used in Programmable Logic Controllers (PLCs) to control and monitor industrial processes.

Define a Variable Using the Context Menu​

  2. Right-click the Data or any other folder in your HMI Data View.

  3. Choose Add Variable.

Augment a Variable With Additional Metadata​

Note:

Float variables do not support Enumerations.

If you want to define Numeric Data Variables that can be restricted to certain values, you have to use Integer.
