Description

tf = isVariableType(NodeObj) returns true (logical 1) for nodes that are variable type nodes, or false (logical 0) otherwise. You can write values, and read current and historical values from variable type nodes.

Identify some node and determine if they are variable type nodes.

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