There's Arduino modbus master/slave library at https://code.google.com/p/simple.... It should work on any microcontroller and compiler provided that you support the library with your own hardware serial library, as they say.
There is a good Modbus library at http://www.freemodbus.org/. Its advantage is that it may be used with many different processors.
