It's highly recommended to connect GND/0V between LM and Modbus device. In some rare cases RS-485 A/B is marked incorrectly and should be swapped.
The settings should be correct, but everytime it says: Operation timed out.
We have tried to change the polarity and with different modbus components.
That's why I asked if we could test if the modbus is working somehow?
