Arduino modbus rtu

Hi all,

i have a problem with the usb modbus rtu arduino,
I don’t know what data was sent by HA which resulted in Arduino always reset,
previously I used HA VM, and no problem happened,
at this time I changed it to the Raspberry Pi 3 B + which has not been used for a very long time, and installed HAOS,
today my entire home automation system is offline because the arduino modbus usb problem is always reset,
Can anyone tell me what needs to be done?
at this time I am lucky that the home electrical installation is still semi-automatic, and all household electricity is still normal, only automation is offline for a while.

spesifikasi :

  • arduino nano 3.0 clone CH340
  • outseal relay shield interface for arduino nano ( outseal plc v.2 ) http://www.outseal.com/
  • 12v omron relay

sorry for bad english, i used google translate for this question.
