Register Allocation For Function 03 / 06 / 16 - Read / Write Holding Registers; Query Poll Registers - Honeywell TPPL Modbus TCP Installation And Setup Manual

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.
Caution: When using Function 6 or Function 16, ensure that the registers related to the command are completely filled
before setting the Block Active flag, otherwise an unintended command may be performed.
