Device Integration

The integration of field devices in process facility networks is highly important to modern industrialization. This is supported by integration approaches using an interpreted or an executable software technology.

We intend to contribute and fill the gap of semantic information exchange. This gap is especially apparent at interfaces between automation technologies (AT) and internet technologies (IT). We bring our competence and experience in device integration and device description approaches to setup new automation architectures e.g. as discussed in Cyber Physical Systems or Industrie 4.0 concepts.         

There is a long experience in device descriptions. ifak was involved in development and standardization of the Electronic Device Description Language EDDL (series of IEC 61804). Based on this knowledge an assisted by several formal compiler tools, ifak has developed an integrated development environment for device descriptions called isEDDworkbench. A demonstration version is available and a commercial version may be purchased by our distribution partner ifak system GmbH (http://www.ifak-system.com/). To get the demo please send an email to matthias.riedl@ifak.eu. A download link will be provided.

Development of EDDL Test Requirements

The device description language EDDL is spcified in IEC 61804. Hence all EDD applications operating such device description shall behave consistently conformance and interoperability tests will be established. These tests are based on precise test cases derived from Test Requirements. The Test Requirements will be developed in this project and are the fundament of the EDD application tests.

Tool integration of field devices using device descriptions

Despite standardised fieldbuses and existing profiles, the manufacturer-specific functions and features are essential parts of field devices. Manufacturer independent tools have to interact with manufacturer-specific functions and features.

EDD Library for PROFIBUS PA V3.02

The profile for field devices used in the process industry has been in some cases enhanced and improved. Hereby practical experiences were regarded allowing the improvement of the efficiency at the commissioning of field devices and to accelerate the data exchange between the field device and the commissioning tool. 

Field Device Integration by means of FDT-DTM

In addition to the usage of device descriptions for the integration of field devices, the application of FDT interfaces (as DTM) is also possible. By ifak, integration based on a DTM toolkit (device descriptions) is carried out.

Investigations of improvements of the information flow during the commissioning of devices

The information flow between field device and Distributed Control System (DCS) is sometimes incomplete when handling difficult failures such as a device breakdown and a subsequent re-commissioning of the plant. Therefore very often manual configurations on the substituted device are necessary. These inter­actions require well educated staff. The project investigated solutions to improve the re-commissioning automatically in relation to the required data and information flow inside the DCS. In addition, ifak investigates how the engineering process can be improved, such as phases from P&I diagrams up to device parameterisation.

isEDD Workbench

Electronic Device Descriptions (EDD) compliant to IEC 61804-3 are being developed inside the isEDD workbench based on various projects. Such a project combines all files belonging to a device description, e.g. dictionaries, include-files, import-files and EDD files. The profile for the EDD can be selected within a project. Therefore the integrated checker can check in detail whether all elements of the EDD are used correctly.

Collaboration for ‘isEDDview DTM’

The generic Device Type Manager (DTM) ‘isEDDview DTM’ is able to handle Electronic Device Descriptions (EDD) according to IEC 61804-3. It supports the communication systems PROFIBUS and HART. Institute ifak has developed the core component, the so called EDD-Interpreter. This component is integrated into the DTM and is being continuously improved.

Tool integration of field devices using device descriptions

Despite standardised fieldbuses and existing profiles, the manufacturer-specific functions and features are essential parts of field devices. Manufacturer independent tools have to interact with manufacturer-specific functions and features. That is why so called device descriptions have to be developed and integrated into the commissioning tools. The Department of Integrated Communication supports field device manufacturers in developing the device descriptions and their integration into the Simatic PDM tool.
