Set up a device.
Understand what it returns.
Use this manual when you need more than a tour of the interface. It covers the Modbus details Busloom exposes, the files it saves, and the checks worth making before you trust a value or write one back.
- FIRST TIME HERE
- Read chapters 01–03, then connect.
- REGISTER MAP READY
- Start with chapters 05–07.
- SOMETHING IS WRONG
- Check chapters 08, 09, 15 and 24.

The manual explains Busloom. These focused guides start from the frame, symptom, or device map you are trying to understand.
