Yokogawa to Join FDT JIG Steering Committee –EDD and FDT/DTM Technologies to Benefit both Customers and Engineers

Yokogawa Electric Corporation announces that it will join the steering committee of the Field Device Tool Joint Interest Group (FDT JIG) to provide customers with more convenient, standards-compliant methods for configuring a wide range of process instruments.

Together with other member companies, Yokogawa will facilitate the expansion of device connectivity and configuration capabilities using standard technologies such as FOUNDATION Fieldbus and HART Profibus. In so doing it will utilize the full capabilities of a wide range of process instruments connected to Yokogawa control systems such as the CENTUM CS3000 and Stardom as well as asset management packages such as Plant Resource Manager (PRM). In addition, through the use of the electronic device description (EDD) and FDT/ DTM (device type manager) technologies, Yokogawa will be able to offer best in class tools for the configuration, diagnosis, and maintenance of its own and other vendors’ field devices and analytical instruments. This solution will allow Yokogawa to offer open technology solutions that integrate process devices into a total plant operation.

Yokogawa appreciates the differences between these two technologies and believes both will bring benefits to customers and engineers. EDD provides system manufacturers with a consistent and unified access path to instruments, while FDT/DTM offers instrument manufacturers the freedom to offer the best configuration tool without interfacing to control systems.

"This participation complements our leadership in the efforts to realize true openness in digital network technology, by driving standards that provide customers with the freedom to use best in class intelligent process devices up to their full capabilities," said Teruyoshi Minaki, Executive Vice President of Yokogawa’s International Business Division and the company’s representative on the Fieldbus Foundation Board. "We see this as a component technology of our VigilantPlant solution to support our customers as they strive for operational excellence."
