Exception | Description |
---|---|
System.ArgumentNullException |
A This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception. |
OpcLabs.EasyOpc.UA.OperationModel.UAException | The OPC UA operation has failed. This operation exception in uniformly used to allow common handling of various kinds of errors. The System.Exception.InnerException always contains information about the actual error cause. This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately. |
This method optionally uses a PubSubConfiguration
file node defined in OPC UA 1.05, or a vendor specific ConfigurationFile
file node, present in servers implemented with Unified Automation (C++) toolkit.
Loading the configuration from a file node is typically faster than accessing it through individual nodes in the information model, but it only provides a one-time snapshot of the configuration.
