PROFIBUS is defined by the German national standard DIN19245 and the European standard EN50170. In the industrial field, PROFIBUS has become a universal, open, and distinctly communicative fieldbus standard.
PROFIBUS is a fieldbus technology used for data communication and control at the workshop level for factory automation, enabling a communication network from the field device level to the workshop level. With its unique technical advantages and wide range of applications, PROFIBUS is at the forefront of fieldbus technology.
PROFIBUS fieldbus is an open fieldbus for communication between devices from different manufacturers. Its transmission speed ranges from 9.6 kbit/s to 12 Mbit/s, varying according to the version.
PROFIBUS consists of three compatible parts: PROFIBUS-DP, PROFIBUS-FMS, and PROFIBUS-PA. Among these, PROFIBUS-DP is a high-speed, general communication protocol mainly used for communication between device-level control systems and distributed I/O, replacing traditional hardwired connections and eliminating wiring maintenance costs, providing high flexibility and reliability for devices.
PROFIBUS-FMS is a fieldbus technology for workshop-level monitoring and data communication and control at the field device layer, with a broad range of applications to meet various automation needs.
PROFIBUS-PA is a communication protocol for process automation, which has a slower transmission speed but offers higher safety and reliability.
The widespread application of PROFIBUS has made it a fieldbus standard with distinct communication capabilities. Its application range covers all industrial fields requiring communication, including petroleum, chemical, electric power, steel, machinery manufacturing, traffic control, food processing, and more.
The main features of PROFIBUS include:
Open Standard: PROFIBUS is an open standard that supports communication between devices from different manufacturers, allowing users to select devices from various manufacturers for configuration, thereby reducing costs and maintenance complexity.
High-Speed Communication: The transmission speed of the PROFIBUS-DP part ranges from 9.6 kbit/s to 12 Mbit/s, meeting various communication needs.
High Reliability: PROFIBUS employs global clock, periodic communication, and handshake protocols to ensure communication reliability and accuracy.
High Safety: The PROFIBUS-PA part utilizes intrinsic safety technology to guarantee safety and reliability in process automation.
High Flexibility: PROFIBUS adopts a distributed structure, adaptable to various application scenarios and supporting multiple communication protocols.
Easy Maintenance: PROFIBUS uses simple wiring methods and universal configuration software, making device maintenance and system integration easier.
In the industrial field, PROFIBUS has become a universal, open fieldbus standard with distinct communication capabilities. Its wide application has made it a fieldbus technology with distinctive features, providing users with significant value and convenience.
