EDDL and FDI (Field Device Integration) are the building blocks of today's and tomorrow's modern process control systems.
Electronic Device Description Language (EDDL) is a programming language used to create Device Descriptions (DDs) to describe the attributes of field devices in an Operating System (OS). It is a universal, proven and state-of-the-art method of accessing diagnostic, real-time and asset management information contained in more than 30 million compliant field instruments from a host of manufacturers, and to provide optimum data and device interoperability. DDs provide device functions such as generic digital and analog input/output modules, HMI displays and transmitters, on-off and regulating valves, and closed-loop controller diagnostics.
With EDDL technology, a user can calibrate instruments, diagnose problems, provide data for user interface displays, identify process alarms and obtain information needed for high-level software, such as MES, UI/SCADA, plant historians, asset management and ERP.

FDI, put simply, is the rationalization of benefits of EDDL and FDT/DTM technologies. Users requested a uniform device integration solution for process industries that combines the broad benefits of EDDL with the enhanced feature sets of FDI. This solution must also span across all host systems and devices regardless of manufacturer. Thus, FDI was born. FDI device packages make it easier for automation suppliers to develop and integrate intelligent devices, because suppliers only need to create a single, unified package for each intelligent device that can work with all host systems and tools. This reduces overall development costs, while preserving and expanding existing functionality. Users will also find it easier to manage information from intelligent devices with a single device package, instead of juggling different technologies and investing significant capital in custom integration efforts to connect multiple technology platforms.
