isObjectType (opcua)

True for object nodes of OPC UA server

Syntax

tf = isObjectType(NodeObj)

Description

tf = isObjectType(NodeObj) returns true (logical 1) for nodes that are object type nodes, or false (logical 0) otherwise. You cannot read current and historical values from object type nodes. Object nodes are used to organize the server name space.

Examples

Identify some nodes and determine if they are object type nodes.

s = opcuaserverinfo('localhost');
UaClient = opcua(s);
connect(UaClient);
nodes = browseNamespace
nodes = 
1x2 OPC UA Node array:
