Typedef Documentation

◆ CVOPCNODE

CVOPCNODE

Handle of an OPCUA Node object.

The following node attributes cannot be changed once a node has been created:

NodeClass
NodeId
Symmetric
ContainsNoLoop

The following attributes cannot be written from the server (but from the client), as they are specific to the different users:

UserWriteMask
UserAccessLevel
UserExecutable

Historizing is currently unsupported

Note: OPCUA nodes are available for different node classes (for details refer to:
https://opcfoundation.org/developer-tools/specifications-unified-architecture/part-3-address-space-model/
for details)

CVOPCNODE objects are reference counted. If one is not needed anymore call the ReleaseObject function of the CVCImg.dll. It is recommended to call the ShareObject function in a program unit (like a class or function) when a handle is set and call ReleaseObject when the handle is not needed anymore.

Function Documentation

◆ CreateCVOPCMethod()

CVOPCNODE CreateCVOPCMethod	(	cvbuint16_t	NameSpaceIndex,
		const char *	Name,
		CVOPCNODEID	Parent
	)

Creates an OPCUA Method Node with the specified parameter.

Note: The default method does not contain arguments. This need to be added by #OpcNAddMArgAsInteger, #OpcNAddMArgAsFloat or #OpcNAddMArgAsString. Callbacks could be registered once the node has been added with #OpcServerAddNode to a Server with #OpcServerRegisterMCallback.

Attention: Always use initialized OPCUA Method Nodes and initialize unused handles with nullptr. Use only initialized parameters to create OPCUA Method Nodes.

Parameters

[in]	NameSpaceIndex	Index of the namespace where the OPCUA Method should belong to.
[in]	Name	String literal for non-localized, human-readable name of an OPCUA Method.
[in]	Parent	OPCUA NodeId of the parent to which the OPCUA Method to be created belongs to.

Returns

#OPCNODE Handle of OPCUA Method Node.
nullptr on error (Use CVOPCGetLastErrorString function for a human readable error description).
