Have a look at Modbusview software. It's not free but it's very low priced. see www.audon.co.uk/modview.html

 

Look at free Modbus software from Watlow. You can look at modbus registers or download programs.
Hope this is what your looking for.

 

Have a look at http://www.focus-sw.com/modpoll

Modpoll is a free command-line master simulator for Windows and
Linux.

I´ve been using a Modbus Software from Win-Tech Inc. (http://www.win-tech.com/) for many years for test purposes. It´s not free, but you can try an avaluation versión.
