Public Properties
 NameDescription
Public Propertystatic (Shared in Visual Basic)Default engine parameters.  
Public PropertyDefault event queue size. The maximum size of the queue each client object uses to temporarily hold generated events before they are consumed by the application. Events that do not fit into the queue will be lost. You should set the size to a number that is sufficient to cope with the difference between the rate events are generated and the rate your application is able to consume them. (Inherited from OpcLabs.EasyOpc.Engine.EasyEngineParameters)
Public PropertyGarbage collection period. Number of milliseconds. Specifies how often the engine reviews the connected OPC servers and items and disconnects from those that are no longer needed. (Inherited from OpcLabs.EasyOpc.Engine.EasyEngineParameters)
Public PropertyMaximum client age. Number of milliseconds. When the engine recognizes that there is a connection to some OPC server that is unused for this period of time or longer, it will disconnect from it.  
Public PropertyMaximum topic age. Number of milliseconds. When the engine recognizes that there is a connection to some OPC item that is unused for this period of time or longer, it will disconnect from it.  
Public PropertyA symbolic name of the current parameter combination if it has a standard name. Empty otherwise. (Inherited from OpcLabs.BaseLib.Parameters)
Public PropertyWorker sleep delay. Number of milliseconds. Specifies how often the engine checks the need to perform tasks such garbage collection, rate adjustment, and final cleanup. (Inherited from OpcLabs.EasyOpc.Engine.EasyEngineParameters)
