Current PROFIBUS specifications include the following: PROFIBUS DP (DP = Decentralized Peripherals) for high-speed data exchange, e.g. with FUs, remote I/Os, analysis devices, etc. (V0, V1, and V2 specifications exist). PROFIBUS PA (PA = Process Automation) was developed for the demands of process automation (sensors, actuators) and covers EEx requirements. Fieldbus supply and communication is handled with 2-line technology. Various device profiles (Profile 3.0) exist for PA devices (e.g. pressure, temperature, etc.).
