| Problem | Possible Solution | |---------|-------------------| | | Check cabling, power, and termination resistors. Verify the slave’s Modbus address and that the baud rate/parity match exactly. | | Connected but no data appears | Ensure the correct COM port is selected (try the highest‑numbered port). Double‑check the function code and register address. | | Software freezes after disconnect | Some older versions may hang when disconnecting. Use Task Manager to force‑close the process. Update to the latest version if available. | | No response in certain register ranges | Confirm that the slave device actually supports the function code and register addresses you are requesting. Refer to the device’s Modbus map. | | Wine cannot see USB adapter on Linux | Ensure the symbolic link under ~/.wine/dosdevices correctly points to the real device node (e.g., ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com1 ). | | Polling works slowly or intermittently | Increase the response timeout value and reduce the polling frequency. Also check the bus for electrical noise or incorrect termination. |
