HART® Communicator - Emerson Process Management

When the DD for a specific device is not available, your HART
Communicator provides a generic interface. This generic interface enables
you to perform functions common to all HART-compatible devices.
Figure 1-22 shows the Generic Online menu tree.
The Online (Generic) menu is the first menu in the generic interface. This
menu displays critical, up-to-date device information such as the process
variable (PV), analog output (AO), lower range value (LRV), and upper range
value (URV). Configuration parameters for the connected device are
accessed using the Device setup option.
The following functions are available from the Generic Online menu:
The SAVE
function key allows you to save a configuration from a
transmitted device. See Changing a Saved Configuration on page 1-29 for
more details.
Device Setup accesses the Device Setup menu, containing configurable
device parameters common to all HART-compatible devices.
PV (Primary Variable) displays the dynamic PV and the related engineering
units. When the PV contains too many characters to display on the Online
menu, press 1 to access the PV menu and view the PV and related
engineering units.
AO (Analog Output) and related engineering units are displayed on the
Online menu. The AO is the signal on the 4–20 mA scale that corresponds to
the PV. When the analog output contains too many characters to display on
the Online menu, press 3 to access the PV AO menu and view the AO output
and related engineering units.
Current LRV (Lower Range Value) and related engineering units are
displayed on the Online menu. When the LRV contains too many characters
to display on the Online menu, press 4 to access the PV LRV menu and view
the LRV and related engineering units.
Current URV (Upper Range Value) and the related engineering units are
displayed on the Online menu. When the URV contains too many characters
to display on the Online menu, press 5 to access the PV URV menu and
view the URV and related engineering units.
