and then the low-Byte. The transferred bytes are not in a rising

sequence, but the higher register follows after the lower register.

• Register 40 returns the status of device M620 and status

over/under voltage alarm.

• Register 41 returns the node address and baud rate.

• Registers 42 to 49 return diagnostic registers per the Modbus

specifications.

• Registers 80 and 81 are read/write registers for over/under

voltage parameter.
