Hi everyone,  
I am trying to find the schema tables which store the metadata configuration of OPC devices such as Modbus TCP, Modbus RTU that I created in Gateway before. The document says that information will be stored in a local database. Does that information exist in tables like the tables in a Database source that stored historical data, user info, etc?

Thank you for your time!

Yes, they’re stored in the internal database, which is a SQLite DB file located at `data/config.idb`.
