PROFIBUS is completely open. It was originally standardized in Germany in 1989 as DIN 19245 and in July 1996 as EN 50 170. The EN 50 170 specification is available through any of the national standards bodies of CENELEC / IEC and the PROFIBUS Specification can be supplied by any of the Regional PROFIBUS Associations. It’s now globally standardized under IEC 61158.
