By "modbus dll" I am assuming you mean you want to create a Modbus protocol library that is compiled and linked into the format used for shared libraries in the Microsoft Windows operating system. 

If you are planning on writing your own Modbus source code, then you need the Modbus specifications. For Modbus specifications, goto "http://www.modbus.org/tech.php". The link to the specs is near the top of the page. You will also need to get a compiler for whatever programming language it is you decide to use. 

If you already have some Modbus source code and are trying to compile it, you will need to read the documentation for whatever compiler the source code requires. You will have to get that documentation from your compiler supplier.

As for how to make a "DLL" library, that will depend on the compiler and linker you are using. You will have to read the documentation provided by your compiler supplier (whoever that may happen to be).

That answers your specific question. If it doesn't solve your problem, then you will have to provide a few more details about what you are trying to do.
