 Q: Why the NAPOPC DA Server show error value when I use Modbus Utility setting address number?

 Ans: 

The Modbus address of Modbus Utility is zero base, and NAPOPC DA Server is one base. For instance, you should assigen address four in NAPOPC DA Server when you want to read the internal register three.
