Emerson Process Management is collaborating with members of leading global standards groups to enhance Device Description Language (DDL) technology. ARC recently published an Insight on EDD Extensions and Standardization. Emerson believes that enhanced DDL offers a better solution than a proposed alternative called Field Device Tool/Device Type Manager (FDT/DTM). In Emerson’s judgment, DDL technology surpasses the FDT/DTM technology in meeting the following needs of end users: freedom of choice of instruments, equipment and systems; clarity and ease of use of HMI design and displays; streamlined integration of field devices; and efficient system upgrades. The company is focusing its resources on enhancement and standardization of DDL, and is collaborating with standards organization members to speed enhancement of the established technology toward the goal of an ever-strengthening HMI interface.
