How to install a new Modbus address on our RS-485 device
- Connect the device to the controller, ONLY this device should be connected via the BUS.
- If you connect several devices on the bus, their performance will be disrupted!
- Run the console commands:
service wb-mqtt-serial stop # stop the standard RS-485 driver
# In the next line, replace "158" with the new address (1 to 247) and "/dev/ttyAPP1" with the controller port to which the device is connected
modbus_client --debug -m rtu -s2 -pnone /dev/ttyAPP1 -a0x00 -t0x06 -r0x80 158 # write new address to device
service wb-mqtt-serial start # start the standard RS-485 driver again
Device firmware update
Starting with the new firmware versions of the device, the firmware update functionality (firmware) via the Modbus Protocol is supported. This makes it possible to extend the functionality of the devices and eliminate errors in the firmware directly at the installation site. Read more about flashing devices described in the article Download firmware to Wiren Board devices. A list of firmware versions that support the update, as well as devices for which this feature is implemented, can be found in Firmware_Changelog.
