Example of a Compound Condition with Derived Fields

A DRV function field can be used to encapsulate a compound condition. The result would be a true/false condition. This can be used in an action diagram or to condition a device field. Similarly, DRV function fields can be used to encapsulate a compute expression.

• Derived fields are equivalent to a function call that returns a single variable.
• Derived fields can be used in any function type and are not restricted to device functions.
