It was developed by Siemens in the early 1980s and standardized in the 1990s. PROFIBUS enhances the level of automation in industrial production by enabling efficient and reliable communication between devices. 1.Development … Read more
Click the blue text to follow us When working in industrial control, we often encounter various types of buses. Today, we will learn about one of them, Profibus, which is a widely used fieldbus communication protocol in the industrial automation sector, primarily for real-time data exchange between industrial devices (such as PLCs, sensors, and actuators). … Read more
Today, let’s discuss an important communication method in the field of industrial automation – Profibus FMS. Although this technology sounds very professional, it is not difficult to understand; it is like a “WeChat group” in a factory, allowing various devices to freely exchange information. What is Profibus FMS? Profibus FMS (Fieldbus Message Specification) is an … Read more
Industrial 4.0 Bus – Profibus What is Profibus? [PROFIBUS] PROFIBUS is a fieldbus standard used in automation technology, promoted in 1987 by Siemens and fourteen other companies along with five research institutes. PROFIBUS stands for PROcess FIeld BUS. PROFIBUS and PROFINET, which is used in industrial Ethernet, are two different communication protocols. PROFIBUS is an … Read more
