Specification and verification of a real-time field bus with formal description languages

In this work the real-time field bus PROFIBUS for industrial communication networks, is specified with the formal specification language LOTOS and its associated tools. The paper introduces the general characteristics of LOTOS and its related tools, and the main features of PROFIBUS particularly the related with its data link layer. The methodology and data types implemented are explained, with an instance of developed performance tests for the specification. Results and new guidelines of this work are explained in last paragraph devoted to conclusions and future works. With LOTOS specification of PROFIBUS protocol comes up the possibility and benefit of using formal descriptions techniques for designs in the field of industrial communications.
