General information about PROFIBUS for SINAMICS

PROFIBUS is an open international fieldbus standard for a wide range of production and
process automation applications.
The following standards ensure open, multi-vendor systems:
● International standard EN 50170
● International standard IEC 61158
PROFIBUS is tuned for high-speed, time-critical data communication at field level.
