Concepts Tasks Settings Creating Calculation Variables Contents Creating a Calculation Type Variable Creating a Filter Type Variable Creating a Global Variable Type Variable Creating a Join Path Type Variable Defining a Factor Table for a Variable Assigning Calculation Variable Limits and Weighting Assigning a Calculation Variable Null Value Behavior Calculation variables are used in calculations and can be derived from four sources. These sources are: • Calculation • Filter • Global variable • Join path The steps involved in creating a calculation variable are: • Define the type of calculation variable(s) to be used within calculations • Define the factor table (numeric variables), if needed • Define limits and weighting (numeric variables), if needed • Define null value behavior, if needed The topics in this section provide an overview of triggered calculations and asset degradation calculations. Asset health calculations are defined via the Asset Health view in APM. For more information, see Creating Asset Health Calculations.
