Hi
To my knowledge, we are not able to directly connect to SCADA gateway and import data from there.
In your scenario, try to use “Get Data->Web” option in Power BI Desktop, enter Web URL and check if you can get any data. In addition, if your system has OData feeds available or database behind it, it is possible to connect straight to the OData feeds or the database from Power BI Desktop.
Thanks,
Lydia Zhang
