In this paper we describe how to integrate Internet Protocols (IP) into PROFIBUS, a typical master-slave fieldbus network. The integration of the TCP/IP protocols in the PROFIBUS protocol rises a number of issues that must be addressed properly. In this paper we particularly address the issues related to the conveyance of IP fragments in PROFIBUS frames (fragmentation/de-fragmentation) and on how to support the symmetry inherent to the TCP/IP protocols in PROFIBUS slaves, which, as in other fieldbus protocols, do not have communication initiative.
