Profisafe becomes national standard in China
Following the successful standardization of Profibus and Profinet in China, Profisafe has now also been elevated to the status of a national Chinese standard as a communication-based safety standard.
Functional safety is playing an increasingly important role in production facilities in industrialized nations - including China. Accordingly, following the successful completion of all standardization work and coordination in the National Standardization Committee, the establishment of a certification laboratory for Profisafe devices and the successful implementation and certification of a first product from an original Chinese company in China, Profisafe has now fulfilled all the requirements for the status of a national standard. Profisafe is now listed in China under the designation 'GB/T 20830-2015'. This was preceded by close cooperation between experts from Profibus & Profinet International (PI) and the PI Competence Center and Test Laboratory ITEI (Instrumentation Technology & Economy Institute, P.R. China) based in Beijing and the Chinese national standards committee SAC/TC124 Industry Process Measurement and Control.
On the one hand, the use of fieldbus-based functional safety enables the establishment of simple safety functions that initiate a safe stop of units at dangerous moments in order to protect people and machines from damage. On the other hand, it also offers intelligent methods for preventing hazards without having to stop production by means of a shutdown process. This could be, for example, reducing the speed of robot movements or self-driving vehicles to a level that allows people moving in the vicinity to easily avoid them. Profisafe provides a technological basis for this and supports these functions within the framework of profiles.
