MODIFY MODBUS ADDRESS
By default the Modbus address of Clever PCB is 1.
If more than one PCB is connected in serial using Modbus protocol, you should give different Modbus
addresses to each PCB board (you can choose from 1 to 255). The Modbus addresses should be introduced
using a binary code to the switch SW1 as examples shown in this table:
PCB number (decimal)
Binary code
PCB switch position
1
00000001
10000000
2
00000010
01000000

After choose an address, you should open the board and turn ON and OFF the correct switches of SW1 for the
desired Modbus address. For example:
After modify the new Modbus address, you should:
•
Remove the power supply or click the reset button 2 seconds
•
Go to initial configuration (basic menu) and press “SCAN” to update all Modbus addresses.
