Displaying Graphics The Fieldbus 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 appear 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 using an
enhanced device description. Only devices using an enhanced EDDL
device description offer graphical representations of data. See
Appendix C for more information about the Graphics functionality.

polling addresses
Polling is a method of determining which devices are present on a
network. The V(FUN) is the first unpolled node address. V(NUN) is the
number of unpolled node addresses. The addresses between V(FUN)
and V(FUN)+V(NUN)-1 are not polled. The default value for V(FUN) is
200 and the default value for V(NUN) is zero. Narrowing the range of
devices being polled provides a quicker Live Device List refresh.
The DeltaV System Polling checkbox instructs the 475 Field
Communicator to use the same polling scheme as DeltaV. The V(FUN)
and V(NUN) options are read-only when the checkbox is selected.
To change the polling addresses:
1.From the Fieldbus Application main menu, double-tap Utility.
2.Double-tap Polling.
3.Enter values in the V(FUN) and V(NUN) fields and tap OK.
