Kit speeds fieldbus products to registration
The Fieldbus Foundation has released its new ITK interoperability testing kit automation tool.
An underlying technology in millions of field instruments installed worldwide, EDDL is a text-based language for describing the digital communication characteristics of intelligent devices and equipment parameters in an operating system (OS) and human-machine interface (HMI) neutral environment.
The technology forms the engineering and operating Foundation on which all major digital bus protocols construct parametric and device descriptions.
The Device Description Workshop examines sophisticated Device Description Language (DDL) constructs and techniques that make device descriptions (DDs) feature-rich for end users.

Kit gets started on Foundation fieldbus
The AT-446 Foundation fieldbus H1 starter kit is a complete, cost-effective solution for automation equipment suppliers seeking a "fast track to fieldbus".
Students will write DDs organising parameters into rich dialogs with images and displaying complex data in graphical format, and learn how to preserve device data and retrieve it for later processing.
According to Fieldbus Foundation President and CEO Rich Timoney, the new workshop shows automation suppliers how to deploy robust extensions to the industry's most widely accepted device description technology.
"EDDL is the process industry de facto standard for ensuring that information about intelligent field devices is consistently available for use by operators, engineers, and maintenance technicians", said Timoney.
"By attending our workshop, device developers can learn advanced techniques for extending the concept of interoperability to the HMI and diagnostic data level with improved visualisation and graphical capabilities".
The Device Description Workshop is intended for instrumentation developers implementing DD files for registered Foundation fieldbus devices.
New and experienced developers will benefit from hands-on instruction in writing and testing actual DDs using the Fieldbus Foundation's DD Tokeniser and new DD Super Viewer tools.
The DD Tokeniser converts DD source files into the DD binary file format, checks for syntax or logical errors in DD source files, and issues error messages that help trace and correct errors.
It also restricts redefinitions of information imported from standard DDs to ensure interoperability.
The DD Super Viewer simplifies the device development process by providing access to the generated DD binary for testing and verification.
The tool also supports rendering the new extensions, including enhanced dialogs, images, graphs and charts.
