BrowsePath Value Attribute Description Attribute
FaultAction   This property determines the action taken on variables in fault state. If the value is TRUE, the value of the property Fault value is used, if it is FALSE, the last valid value is used
FaultValue   This property specifies a user-defined value for use with Fault action property
FeedbackVariable   Variable quantity, which represents the controlled variable and is returned to the comparing element
   FeedbackVariable

Description: percent
 
ManipulatedValue   Output variable of the controlling system, which is also an input variable of the controlled system
OnOff   This property enables the operation.
