| Name | Description | |
|---|---|---|
 | BrowseNodesChunk | Number of nodes requested in one call when browsing for OPC branches or leaves. |
| ClientReconnectDelay | Client reconnect delay. Number of milliseconds. If operations on specific OPC server are found to be failing, the server is disconnected, and further connection is retried only after the client reconnect delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters) |
| ComInstantiationParameters | Contains parameters that influence instantiation of OPC servers. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters) |
 | Default | Default client parameters. |
| ElementNameCaseSensitive | Indicates whether the element names in the OPC server are case-sensitive. This value is used when the element name is matched with element name filter pattern for OPC-DA 1.0 and 2.0 servers that generally cannot do the element name filtering internally. |
| LinkCallbackQueueSize | Size of the internal queue that holds callback data from the OPC server. |
| RequestQueueSize | Size of the internal queue that holds requests related to operations on OPC items. |
| ResponseQueueSize | Size of the internal queue that holds responses related to operations on OPC items. |
| ServerFailedReconnectDelay | Server failed reconnect delay. Number of milliseconds. If the OPC server indicates that vendor specific fatal error has occurred within the server, the server is disconnected, and further connection is retried only after this delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters) |
| ServerShutdownReconnectDelay | Server shutdown reconnect delay. Number of milliseconds. If the OPC server indicates that it needs to shut down, the server is disconnected, and further connection is retried only after this delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters) |
| ServerStatusCheckPeriod | Server status check period. Number of milliseconds. Determines how often the system periodically checks the status of the OPC server (by calling IOPCServer::GetStatus method). (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters) |
| StandardName | A symbolic name of the current parameter combination if it has a standard name. Empty otherwise. (Inherited from OpcLabs.BaseLib.Parameters) |
| TopicProcessingIntervalTimeout | Topic processing interval timeout. Number of milliseconds. When the incoming requests related to OPC items pause for this interval, the requests collected so far are applied to the OPC server. |
| TopicProcessingTotalTimeout | Topic processing total timeout. Number of milliseconds. When the incoming requests related to OPC items are being collected for this period, the requests collected so far are applied to the OPC server. |
| TopicRetrialPeriod | Topic retrial period. Number of milliseconds. Determines how often will the component run the internal process to re-connect to OPC items that have failed (e.g. due to incorrect Item IDs). |
