To connect a OPC UA client, running on the ctrlX CORE, to a remote master we need to call the 'connect' method in the 'opcuaclient' node in the datalayer. One way to do this is by connecting via a external OPC UA Test Client to the OPC UA Server (OPC UA Client and Server Apps need to be installed on the ctrlX CORE) and execute the call there (App Version 1.10.0).
How can this method call be realized in NodeRed?
Solved! Go to Solution.
the connect function is implemented as datlayer write service. So you can do a write on the address opcuaclient/MLC_/connect without arguments.
Thank you for the fast reply. Could you attach an example / screenshot, showing how to to this WRITE without arguments in the ctrlX NodeRed App?
Thank you in advance.
