(Новая страница: «===Changing Modbus Device Addresses=== For devices that support Fast Modbus, you can set new addresses by accessing the device using its unique serial number. This is convenient when multiple devices with the same address are detected on the bus. Changing addresses is done using the ''wb-modbus-scanner'' utility and is currently not supported through the web interface.
