Software for EDD engineering tools

31 March 2009

PI (Profibus & Profinet International) is providing its members with two powerful software components for distributing device descriptions based on EDDL. These include an EDD import library, which supports the development of IEC-compatible EDDs for Profibus PA devices and an interpreter software for these EDDs for use in engineering tools.

Device descriptions based on the EDDL technology are widely used in process automation. The EDD import library is an IEC-compatible library of basic elements which can be used for very efficient development of EDDs for PROFIBUS PA devices. The scope of delivery of the EDD import library also includes the source text files and corresponding documentation with implementation instructions. PI member companies can download the EDD import library free of charge from the PI website: www.profibus.com.

An interpreter software is available immediately for processing EDDs in PC-based tools. The interfaces are disclosed and documented where necessary so as to allow easy integration into tools from different suppliers. The scope of delivery includes the object code of the core interpreter software, a sample client in source code and the required documentation.

The EDD interpreter is also integrated in the testing system for certification of Profibus products, which handles testing of the EDDs.

Electronic Device Description Language (EDDL) technology is used by major manufacturers to describe the information that is accessible in digital devices. Electronic device descriptions are available for over 15 million devices that are currently installed in the process industry. The technology is used by the major process control systems and maintenance tool suppliers to support device diagnostics and calibration.

For an update on Profibus, Profinet, PROFIsafe and wireless industrial communications, readers are recommended to attend the Profibus & Profinet User Conference at Stratford Manor Hotel, Stratford on Avon, June 16/17 2009 where industry experts will present the latest on the technologies and their application in a packed programme of technical presentations and hands-on workshops. Full details and the Conference Programme and reservation form can be found on the conference website at www.profi-bus.co.uk.
