Fieldbus systems have a proven track record that goes back to the early 1990’s, and PROFIBUS has been at the forefront. These systems are deployed throughout the industrial automation landscape in the automotive, machinery manufacturing, food & beverage, pharmaceutical and chemical industries. Somewhere in the region of 50 million PROFIBUS nodes are currently installed in the field. They ensure reliable process data transport, simplify engineering design and installation, and play a key role during ongoing operation.
PROFIBUS PA has been used in process automation for more than 10 years. Over 8 million field devices already communicate using PROFIBUS DP/PA in this arena, generating significant value-add for users. Device power and process data, as well as device status signals and diagnostic data, are delivered via the bus cables.
