Profibus Insights

What is Profibus?

PROFIBUS (Process Field Bus) is a standard for fieldbus communication in automation technology. It is widely used for communication between programmable logic controllers (PLCs) and distributed I/O devices, sensors, and actuators in industrial applications. PROFIBUS is known for its reliability and deterministic communication, making it suitable for real-time control systems.
