Graphics
The HART Application offers graphical views of device
data by using the enhanced Electronic 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 are not 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.
