Profinet IO is a leading global industrial fieldbus standard based on industrial Ethernet technology. It provides a complete network solution for automation communication, encompassing current hot topics in the automation field such as real-time Ethernet, motion control, distributed automation, fail-safety, and information security. Profinet IO's openness ensures high flexibility in factory architecture and production processes, its quick and easy configuration accelerates system commissioning, and its comprehensive diagnostic and maintenance mechanisms minimize maintenance costs. Simultaneously, Profinet IO's high transmission rate and stable, reliable data communication ensure steady improvement in equipment performance.
Today, Profinet IO has nearly 10 million node devices installed worldwide, making it the industrial automation bus standard with the highest market share based on industrial Ethernet technology.
On September 16, 2014, the National Technical Committee on Standardization of Industrial Process Measurement and Control (SAC/TC124) held a press conference and report meeting at the Diaoyutai State Guesthouse in Beijing to release the recommended national standard GB/T 25105.1~3-2014 "Industrial Communication Networks - Fieldbus Specifications - Type 10: Profinet IO Specification" (3 parts). Dr. Sun Wei, Deputy Director of the Information Technology and Automation Division of the Industrial Standards Department II of the Standardization Administration of China, attended the meeting and announced that the Profinet IO technical specification had officially become a recommended national standard. This means that the Profinet IO industrial fieldbus technical specification based on industrial Ethernet will be more widely used in the Chinese market in the future, helping Chinese customers achieve flexibility, efficiency, and high performance.
The Profinet IO technical specification, which has been approved by the Standardization Administration of China as a recommended national standard, consists of three parts: "Fieldbus Specification Type 10: Profinet IO Specification Part 1: Application Layer Service Definition" (GB/T 25105.1-2014), "Fieldbus Specification Type 10: Profinet IO Specification Part 2: Application Layer Protocol Specification" (GB/T 25105.2-2014), and "Fieldbus Specification Type 10: Profinet IO Specification Part 3: Profinet IO Communication Standards" (GB/T 25105.3-2014).
The Profinet IO technical specification defines the communication standards between controllers and distributed I/O. In 2010, Profinet IO was approved as a national standardization guidance technical document in China. In the following four years, the application of Profinet IO in China grew rapidly, and many domestic companies began to independently develop I/O devices, switches, instruments, and other products compliant with the Profinet IO technical specification. A Profinet testing laboratory authorized by Profibus & Profinet International was also established in China. With its high speed, security, stability, and flexibility, Profinet IO has been widely applied in the Chinese market, covering industrial automation and motion control fields such as power, metallurgy, petrochemicals, transportation, papermaking, printing machinery, and packaging machinery.

Now that it has become a recommended national standard, the Profinet IO technical specification will be more widely used in the Chinese market. Under a unified technical standard, Chinese customers will find it easier to expand their systems, improve production efficiency, and reduce costs.
