Yokogawa Electric Corporation has joined the PROFIBUS, an interest group for the PROFIBUS and PROFINET standard communication protocols that are widely used in industrial automation applications.

Originally developed to meet the needs of the discrete manufacturing industry, PROFIBUS has evolved into a fieldbus standard for both discrete manufacturing and process automation.

PROFIBUS and PROFINET are standardized under a range of international standards, the most important being IEC 61158 and 61784. www.yokogawa.com/us.
