Reference

NOTE:

In true Modbus, 3X and 4X Registers are numbered starting at 1. This is known as ‘one based’ addressing.
However, when transmitted to a slave over the serial link, the actual address transmitted is one less.
Some Modbus masters will allow for the first register number to be 0. This is known as ‘zero based’
addressing. If this is the case, the Modbus register numbers listed in this manual must be offset by -1 to
properly program a master using ‘zero-based’ addressing.
