Displaying The Connected Hart Devices - Emerson 475 User Manual

HART Functionality
Displaying the Connected
HART Devices
After the device is connected, double-tap HART Application from the Field
Communicator Main Menu. The HART Application automatically polls for connected
devices using the selected polling options. See "Changing the HART Polling Options"
on page 3-15 for information on modifying these options.
NOTE
Communication errors, such as a device appearing at multiple addresses, can occur
when polling addresses greater than 15 on a loop with both HART revision 5 or earlier
and HART revision 6 or higher devices.
For many devices, an Online menu similar to Figure 3-7 is the first menu to appear
when connected to a HART device and is the root menu for the device. This menu
displays critical, up-to-date process information that is continuously updated, including
device setup, primary variable (PV), analog output (AO), PV lower range value (LRV),
and PV upper range value (URV). If a different Online menu appears, see your device
documentation for details on the available menu options. The menus and configuration
parameters for devices vary because they are defined in the device description. See
your device documentation for more information.
NOTE
Dynamic variables shown while online represent the digital data being sent from the
device.
Figure 3-7. HART Online Menu Example
Because the Online menu displays important information, some submenus display the
HOME button to return you to the HART Online menu.
