Good time of day! I am beginner. Please help!!! What is the difference between node-red-contrib-opc-da and node-red-contrib-opcda-client? In my telemetry project, i use OPCDA-server. What node i need use for reading data from OPCDA-server?

Greetings node-red-contrib-opc-da is part of the OPC-DA packages maintained by ST-One. This other node you mentioned, node-red-contrib-opcda-client is a node mantained by @emrebekar that add the possibility of writing to the server. Currently if what you need is reading data from an OPC-DA server, using node-red-contrib-opc-da will be enough. As far as I know both use the same library node-opc-da created by ST-One.

Best regards

Great! Igor! I have some problem to connect node-red-contrib-opc-da to OPCDA-Server (LacroixTelemetryOPCServer). I assume that LacroixTelemetryOPCServer is not standart and only works correctly with the LacroixOPCDA-client. Can you take the time to test node-red-contrib-opc-da with LacroixTelemetryOPCServer? I can configure for you remote access to my test-LacroixTelemetryOPCServer. The data on the OPCDA-server is updated every 15 minutes. IP/log/psw - i am ready to send it to your personal e-mail. I only need your confirmation of correct operation node-red-contrib-opc-da with LacroixTelemetryOPCServer. Please help!!!!

Hi Pol-65! I have to do exactly the same. I also have a LacroixTelemetryOPCServer and I want to parse data into MQTT topics. Bumped into this thread by chance and I'm totally astonished as LacroixTelemtryOPCServer doesn't seem to be widely spread. Did you finally manage to connect node-red-contrib-opc-da to LacroixTelemetryOPCServer?
