ISA104, Electronic Device Description Language (EDDL)

Visit EDDL.org

Scope

To create a standard that specifies a generic language to describe the properties of automation system components. The specified language shall be capable of describing:

• device parameters and their dependencies;
• device functions;
• graphical representations, for example charts;
• interactions with control devices.

The language is called the “Electronic Device Description Language (EDDL)” and is used to create an “Electronic Device Descriptions (EDD)” file. These files may be used with appropriate tools to generate interpretative code to support parameter handling, operation, and monitoring of automation system components. Tool implementation is outside the scope of this specification.

This Standard shall specify the semantical and lexical structure in a syntax independent manner. A specific syntax shall be defined, but it is possible to use the semantical model with a different syntax.

NOTE: The Electronic Device Description Language may also be used for the description of product properties in domains other than automation systems, but these other domains will not be specifically addressed.

Purpose

To standardize a Descriptive Language intended for use in industrial automation applications. These applications may include devices such as generic digital and analogue input/output modules, motion controllers, human machine interfaces, sensors, valves, closed-loop controllers, encoders, hydraulic valves, and programmable controllers.
