Auto Scan Settings:
Add or delete the ID,Function code and register of RTU.
Check:
Click on “Check”, LoraUtility will read the configuration from LC.
Apply:
Click on “Apply”,make the settings take effect.
“LC Timeout“ on LC144:

LC/LM - ModBus RTU Protocol (Register Control Table)
The WoMaster LoRa Node device is developed base on Modbus RTU protocol. Most of
control and communication parameters can be read or write by Modbus RTU protocol
through the RS485 interface. In the LoRa MAC Transparent architecture, the Modbus
RTU Host can easily attached the remote, far
-
end Modbus RTU slave devices through the
LM100 and LC100 series. Besides, the analog information of LC100 also can be polling by
traditional Modbus RTU protocol. The following table shows the Modbus Register
information.
