cvb.opcua.NodeID create	(	int	namespace_index,
		Union[int, str]	identifier
	)

Creates an OPCUA node ID based on the given namespace and identifier.

Parameters

namespace_index : int Index of the desired namespace.

identifier : Union[int, str] An identifier as a source.

Returns

cvb.opcua.NodeID The node ID object.

create_namespace0()

cvb.opcua.NodeID create_namespace0

(

int

namespace0_node_id

)

Creates an OPCUA node ID based on a pre-defined namespace 0 value.

In contrast to the NodeID.create method, this version creates a node ID in a pre-defined namespace.

Parameters

namespace0_node_id : int Namespace0 node ID (see cvb.opcua.Namespace0NodeID).

Returns

cvb.opcua.NodeID The node ID object.

Property Documentation

identifier

identifier = property

static

Union[str, int]: Gets the identifier.

For determining its type, read a value by calling cvb.opcua.NodeID.type.

namespace_index

namespace_index = property

static

int: Gets the namespace index.

A namespace index is an index which this node ID is associated with.
