Register
Changing the Modbus Device Address
The Modbus device can be changed using either the MBID command or directly through
Modbus. Refer to the Command Mode instructions to set the address using the command
mode.
Modbus register 40200 contains the unsigned 16-bit address. Writing to this register will
update the device's Modbus address. The write request will be acknowledged but will
change immediately after the response has been issued. The valid address range is 1
through 255. Write requests outside this range will not update the address. The address is
stored in flash memory and will remain in affect permanently or until it is changed again.
