Hi there,

you were right, i had added influxDB as a datasource to grafana on the machine thats running RapidSCADA and Grafana.
I changed the port of Server and Communicator to 10003 (10001 and 10002 wasnt working for me) and then it was fine again.

Thank you,

David

Once again, also that worked perfectly. You are really really great.
Thank you again, thanks for your work and constant and quick help and
response. Is there any way one can support you?

[OPCUser]

That was the problem, indeed. Its working now, thanks a million times.

Is there a way to restart the OPC UA server after adding new variables
to the subscription group? I always have to reboot the entire pc
to make it work.

Hi Mikhail,

stopping the service and starting the worker did the trick
and i do receive values now.

Here is the ScadaComm.log:

This seems to be working.

The OPC UA server is having troubles though. As you can see there are some problems regarding opening listener sockets.
I am able to connect to to UA Server with UA Expert but i dont have access to
the variables. I can browse the tree up to the device folder but thats it.

Thank you very much for your help so far.
Greetings.
