isObjectType

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:
    index     Name      NsInd  Identifier  NodeType  Children

      2    Scalar       2      10159       Object    29

isObjectType(nodes(1))

ans =
     0
