ISO/OSI Reference Model
In accordance with the international ISO/OSI model, a fieldbus protocol can be uniquely described by means of up to 7 transmission levels. Specific tasks are assigned to each level in this system. PROFIBUS DP and PROFIBUS PA use only the first two levels as well as the user interface, which resides in level 7 and where application functions that can be utilized by the user are determined along with system and device behavior. Level 1 defines the physical aspect of transmission (physical layer). This includes, for example, the method of transmission, the transmission medium, and lengths of lines, while level 2 specifies the bus access protocol (data link layer)
