Detailed Description

Various information elements of a Condition are not considered to be states. However, a change in their value is considered important and supposed to trigger an Event Notification. These information elements are called ConditionVariables. ConditionVariables are represented by a ConditionVariableType. It defines the mandatory Property SourceTimestamp.

Constructor & Destructor Documentation

UnifiedAutomation.UaServer.ConditionVariableModel.ConditionVariableModel ( )

UnifiedAutomation.UaServer.ConditionVariableModel.ConditionVariableModel ( ConditionVariableModel  template,
DummyArgument  dummy = null 
)

Initializes a new instance of the ConditionVariableModel class.

Parameters
templateThe template.
dummyDummy argument to enable writing own constructors that are called by the generated code.
