Handheld communicator Model DHH805-A |
OI/DHH805-EN Rev. D 21
7 HART
®
Communication
7.7.4 Configuration management - Clone
Configuration cloning allows users to double a configuration
stored on DHH805-A. After selecting the configuration to be
cloned, the handheld terminal shows the same screen as per
figure 26. Configuration is loaded, and DHH805-A redirects
user automatically to the device type menu entry.
7.8 Online menu mode
Online Setup is the normal HART
®
communication mode. This
mode enables communication with HART
®
field devices at the
Universal, Common Practice, and Device Specific Command
levels for full device setup and functionality.
Menus displayed for the connected device follow the HART
®
device manufacturer’s menu structure.
If user does not have the dedicated DD file, DHH805-A will ask
if the user wants to use a generic DD (see figure 28)
Figure 30: Device status message
DHH805-A can display four different status:
— LCF (Loop Current Fixed): the generated current is
different from the reading of the instrument. This mismatch
can occur when user is performing current output
simulation or a polling address has been set.
— MAL (Device Malfunctioning): the connected instrument is
not working properly. User can find further details under DD
diagnostics.
— MSA (More Status Available): DD diagnostics is to be
checked.
— PRO (Process): handheld terminal shows this status
message when device variables (process and non-process)
are out of limits as well as when the loop current is
saturated. More details can be found under DD diagnostics.
7.10 Save / send configuration functions
HART
®
device configurations may be saved to DHH805-A SD
Card memory (8 Gb) or sent from the handheld terminal
memory to a HART
®
device. These functions are useful for
cloning a device configuration for use in another transmitter of
the same configuration, for recording as-found and as-left
configurations for later review, for returning HART
®
devices to
previously used configurations, etc…
The Save / Send function may be accessed in one of two
ways:
— Press the right navigation key (OK) when the device has
been found (see figure 26). DHH805-A loads the DD file
and user accesses the Online main menu. Save / Send
commands are located within Configuration Handling.
— From the main screen appearing after activating the
device (see figure 29 here below), select Settings > Device
List. DHH805-A polls the address(es) and will return the
same screen as per figure 28. Then proceed as mentioned
above.
7.9 Device status warning
Device status warning can be shown on the top-left-hand
corner of the DHH805-A display (see figure 29).
