Devices get better and better. The challenge for a new project and over the life cycle of an operational plant is managing different versions of devices using digital communication. More than one version of the device may arrive on site, from the manufacturer's different locations, reseller's stock, as part of package units, or as ongoing replacements.

EDDL (IEC 61804-3) is a device integration technology created as a solution to the device revision problem. EDDL makes managing devices of different types and versions easier.

EDDL works the same way for HART, WirelessHART, FOUNDATION fieldbus, and PROFIBUS. EDDL is required to configure and calibrate 4-20 mA (with HART) devices before they can be commissioned.

The Electronic Device Description Language (EDDL), formerly known as just Device Description (DD), has been supporting device revision management since circa 1992. EDDL is a device integration technology. EDDL is an integral part of HART, FOUNDATION fieldbus, PROFIBUS, and WirelessHART protocols.

That is, thanks to EDDL the system is kept evergreen and up to date with new devices. Keep systems up to date and compatible with new devices by loading the EDDL file for the device onto system. All versions of all device types from all manufacturers can thanks to EDDL be managed from the same software
