This Technical Report (TR) provides an evaluation and assessment of electronic device description language (EDDL) technology. It provides guidance to device and system manufacturers for how EDDL technology can help them meet user requirements. It provides guidance to system integrators, as well as instrumentation and maintenance practitioners at end-user companies, on how EDDL technology can help them integrate systems and incorporate device management in their work processes. This TR gives examples of requirements from the NAMUR NE 105 recommendation. It is the intent of this TR to illustrate how EDDL technology and products based on EDDL technology meet these requirements. This TR provides a current assessment of the capability of the EDDL technology and the features and capabilities it enables in devices and tools such as handheld field communicators, distributed control system (DCS) engineering software, DCS operator software, device management software as part of plant asset management solutions, as well as stand-alone software for use in laptop or tablet computers.
