TestConnection Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub.Extensions Namespace > IEasyUASubscriberExtension2 Class : TestConnection Method
Tests whether an OPC UA PubSub connection can be successfully established. Synchronous.

The method returns normally when the test passes. The method throws a OpcLabs.EasyOpc.UA.OperationModel.UAException when there is an error establishing the connection.

Due to asynchronous nature of some communication channels, successful test outcome does not always imply that a connection has been fully established.

The waitMilliseconds parameter is not a timeout in its traditional sense, i.e. a maximum time allowed for the operation. Here, this method actually waits for the time given by waitMilliseconds parameter unless a failure occurs.
