Fieldbus lubricates refurbishment

Shell has used Norgren’s fieldbus technology in refurbishing its lubricant plant in Hamburg, Germany. The lubricant plant, thought to be the largest in the world, has over 7500 inputs and outputs in the system. Fieldbus (Profibus-PA and Profibus-DP for main plant operation, AS-Interface for control of the valves and sensors) saves a significant amount of money on cabling design and installation time.
