Modbus is a popular (and cheap/easy) protocol that all Schneider/Modicon PLCs speak. It is cheap because it is in the public domain and everyone has written drivers using that. Twidosoft and Twidosute (free downloads) botj contain Modbus drivers that can be configured, verified, and run with the Modicon PLCs.
