ProfiBus (Process Field Bus) is a pivotal industrial communication protocol widely used in automation control systems. Developed in the late 1980s, it facilitates real-time data exchange between devices like PLCs, DCS, sensors, and actuators. With two main variants, ProfiBus DP and ProfiBus PA, it caters to diverse industrial needs.
Operating within a voltage range of -7V to +12V, ProfiBus utilizes the ProfiBus signal for efficient communication between devices. Its adaptability and reliability make it a cornerstone in industrial automation, enhancing efficiency and flexibility across various sectors.
