OpcAutomatism Members

Gets or sets a value indicating whether a new instance of the OpcNodeId, which is created using a String as the Value, have to automatically parse the String passed to the constructor.

C#

public static bool AlwaysParseStringIdentifiers { get; set; }

Property Value

Boolean

The value true if the String passed as the Value is to be parsed automatically to determine any namespace information encoded in the String; otherwise the value false. The default value is false (since version 2.9.0.0).

Remarks

The logic behind this option is legacy and is obsolete. Beginning with version 2.9.0.0 the old automatism (parsing the node identifier value within the constructor) is only enabled if this property is set to the value true. It is recommended to port user code to take aware that the OpcNodeId uses any String passed as its Value and will not longer automatically inline parse the value for more flexibility. Is such a logic required then the node identifier is to be parsed by user code to have more transparency.

Gets or sets a value indicating whether the OpcNodeManager base shall ensure that instances created through CreateNodes(OpcNodeReferenceCollection) do not reference a namespace equals to the Default namespace. In cases there the default namespace is referenced by the Id and the Name property of an object implementing the IOpcNode interface they are automatically adjusted to use the DefaultNamespace of their OpcNodeManager instead.

C#

public static bool AssignDefaultNamespaceOfManager { get; set; }

Property Value

Boolean

The value true if the Namespace of the Id property and the Namespace of the Name property of all IOpcNode instances is to be verified and adjusted to use the DefaultNamespace of their OpcNodeManager; otherwise the value false. The default value is true.

Remarks

Changing this property to the value false may improve the startup performance, but also requires manual ensurance of valid OpcNamespace references in OpcName and OpcNodeId instances assigned to the properties of an object implementing the IOpcNode interface.

Gets or sets a value indicating whether the SDK shall use generic types to represent OPC UA server defined custom types. To do so OPC UA client applications will determine the necessary type information from the server directly after a connection to the server has been established.

C#

public static bool UseDynamic { get; set; }

Property Value

Boolean

The value true if the SDK shall use generic types constructed from the type information offered by the server; otherwise the value false. The default value is false.

Gets or sets a value indicating whether OpcTypes shall automatically registered by the SDK during the first startup of an OPC UA application start up. Such a startup means in case of a client application that a client will register application defined types on its own before connecting to a server. In case of a server application the server will register application defined types on its own during its startup.

C#

public static bool UseDynamicTypeRegistration { get; set; }

Property Value

Boolean

The value true if application defined types shall automatically registered by the SDK whenever a client application connects to a server or a server starts up for the first time. The default value is true.
