Device Description Language, the standard of Hart Communication Foundation, has been approved by the International Electrotechnical Commission as IEC61804-2.
Device Description Language, the standard of Hart Communication Foundation, has been approved by the International Electrotechnical Commission (IEC) as an International Standard (IEC61804-2) by unanimous vote.
Hart was the first communication technology to implement Device Description Language (DDL) as its standard.
DDL is the only technology endorsed by the Hart Communication Foundation (HCF) for configuration of Hart devices.
"For more than a decade DDL has proven its value to both users and manufacturers as a standard environment for accessing unique features of Hart-enabled devices," says HCF Executive Director Ron Helson.
"The HCF is committed to DDL and is actively working to enhance the technology with new tools and capabilities to further strengthen the platform and facilitate new product applications." DDL has been a key element of the Hart technology since 1990.
It has proven to be an efficient and stable platform to describe the capabilities of Hart-enabled products in a single, open and consistent format.
Device descriptions, created in DDL, provide information for handheld configurators, host control systems and asset management applications to access, display and modify device unique parameters in Hart smart field devices.
