1 The EDDL Technology
The Electronic Device Description Language (EDDL) is a text-based language that may be used to describe
the characteristics of field devices.
It is very similar to HTML web pages concept. There’s an EDDL text file that tells which commands to send
to request data, how to decode answers from the filed device and how to display data on the user interface.
The text file is managed by an “EDDL interpreter” in the same way as a “web browser”.
The EDDL is used to create Electronic Device Description (EDD) files that are used by host systems (e.g.
AMS) to communicate with field devices independently by communication protocol and operating system of
the field device.
With EDD files is provided a standardized access to filed devices data: online data are displayed in a
graphical way that makes devices easy to use.
