|
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 |
||
|
NamespaceUri: http://www.opcfoundation.org/UA/units/un/cefact UnitId: 20529 DisplayName: % 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. |
||
|
ReferenceVariable |
|
Input variable to a comparing element in a controlling system, which sets the desired value of the controlled variable and is deducted from the command variable |
||
|
