    ODBUS ONFIGURATION 4.6 Register Allocation for Function 03 / 06 / 16 – Read / Write Holding Registers All registers use 16 bit data words. The Channel Type field identifies the channel as Input or Output. The decimal value 105 (= ASCII ‘i’) is used for Inputs. Function 16 can be used to write to the 40n01 to 40n04 and 41n01 to 41n05 (n = 0 to 9) ranges of registers only.
