Enhanced Interoperability with EDDL and OPC at ISA EXPO 2009
OPC unleashes information in devices using the international standard IEC 61804-3, Electronic Device Description Language (EDDL)
Scottsdale, AZ, October 6, 2009 – The OPC Foundation is participating in the ISA104 committee’s EDDL booth at the ISA Expo 2009, 6-8 October 2009 in Houston, Texas, USA, together with the Fieldbus Foundation (FF), Hart Communication Foundation (HCF), the Profibus Nutzerorganisation (PNO) demonstrating support for the Electronic Device Description Language (EDDL) technology and reflecting the collaborative partnership between these organizations in defining state-of-the-art for system integration.
One of the key issues facing end-users today is how to take equipment—devices, controllers, networks—and integrate them into their businesses’ enterprise and asset management systems. EDDL (www.eddl.org) and OPC address end-user concerns on how to achieve transparent backward compatibility, providing a solid base for interoperable device configuration, diagnostics and monitoring for tens of millions of actual devices installed in the field, comprising of literally thousands of different device types. OPC provides system integration, operation, and asset management for all devices, independent of the fieldbus technology employed. The versatile EDDL is integrating information into hand-held field communicators and thanks to OPC, up to the Manufacturing Execution System (MES) and beyond.
EDDL is used by control systems to automatically configure their OPC servers to make all data in underlying intelligent devices using a mix of HART, FOUNDATION fieldbus, PROFIBUS, or WirelessHART from different manufacturers available from the same server to any OPC client. This includes not just bringing process variables to plant historians and statistical process control, but also the ability to bring device diagnostics to Safety Instrumented Systems (SIS) or messaging software that send email to service personnel anywhere or text to mobile phones. Auto tuning software use OPC to analyze and optimize control in field devices. For small engineering trials this information can be brought into Excel or a desktop historian.
System integration based on OPC is about multi-vendor interoperability and easy access to data. EDDL makes the vast amount of setup information and diagnostic data in intelligent devices accessible to software, enabling automatic configuration of the OPC server, without manual data mapping, which in turn makes system integration using OPC even faster and easier. This solution for OPC servers owes much of its ease-of-use to the open standard configuration power of EDDL. EDDL saves numerous man-hours of OPC server configuration and speeds up project completion.
EDDL is platform independent much like OPC-UA and text-based suitable for a web services oriented architecture. Devices are described with text-based files for functions such as diagnostics, configuration and calibration. OPC together with EDDL allows the data in the devices to be accessed. And it does this without affecting the reliability and integrity of the control system—a key user requirement—because no device drivers need to be added to the system to make it work. EDDL is the only device integration solution that is declarative. Therefore there are no other means to achieve a comparable result.
All ISA EXPO 2009 attendees are encouraged to stop by booth #1117 to learn about this open, interoperable device integration standard.
The ISA104 standards committee, Electronic Device Description Language (EDDL), continues its efforts to provide education and information on the international standard IEC 61804-3. This standard has been adopted by ISA / ANSI for use with HART, PROFIBUS, and FOUNDATION fieldbus. Learn more about ISA104 and EDDL at www.isa.org/isa104 and www.eddl.org.
