Device Description Language (EDDL) technology.
Device data can be presented as images, charts, and
graphs. These options are displayed as items in the
Online menu and its submenus. The placement of the
Graphics options in the menus varies from device to
device because it is determined by the device
manufacturer.
To view the graphical representations, you need a
device with enhanced EDDL, a 375 Field Communicator
with a Graphics license, and 375 system software
version 2.0 or higher. Only devices with enhanced EDDL
offer graphical representations of data. If the 375 Field
Communicator does not have a Graphics license,
enhanced DDs can still be used. However, the graphical
representations will not be displayed.
The Graphics license can be purchased through your
375 sales representative. The Graphics license can then
be enabled in a 375 by using the Online Licensing
feature in the Easy Upgrade Programming Utility. See
Appendix C for more information about the Graphics
functionality.
