I'm trying to connect to a OPC UA server using the Industrial Comunication Toolbox's command opcua():

uaClient = opcua(serverUrl);

But while trying to connect it gives me the a "Error using opcua (line 46) Initialization error. InternalError."

I don't know what is the cause of the error. I'm using just the command opcua() and the error appears and the OPC UA server is working correctly.

Did you complete the <Initialization Steps> before trying? If not, be certain to have done and then try again.
