Receives an integer value from a *ProtectionOperate-type Measurement, as a shortcut to that Measurement's value. This property informs the current situation of a Protection's operation. Possible values for this property are -1: No configured operation (default), 0: Normal, or 1: Operated. This property makes it easy to create objects, whether Screen objects or data objects, that need information about a Protection's operation, by simply reading this property, instead of searching for a Protection's child object. This is a read-only property.
