Manual Launch of Device 0 Poll
When the message
Device 0: *On-line*
is displayed on the YHC Main
navigation screen, selecting
Online Setup
will launch HART
communication with the device. The message indicates that a HART
device with address 0 has been detected at the HART connection and the
YHC is standing by to initiate communications. The
Device 0: *On-line*
message is shown 1) if a physical connection is made to a HART device
after the YHC power is turned on or 2) if the user exits from a HART
communication session without disconnecting the lead wire by using the
soft key controls provided.
Offline Menu Mode
The
Offline Menu
gives the user access to lists and functions that can be
viewed or performed in Offline Mode at the user’s convenience for the
purposes of reviewing the YHC’s DOF list, reviewing stored device
configurations or creating HART configurations. Stored configurations
can also be edited and then applied later to a connected HART device.
When the
Offline Menu
is selected from the
YHC Main
navigation
screen, the display at right is shown.
1 List / Show DOFs:
Provides a list of installed DOFs (Device Object Files) used by the YHC to
communicate with HART devices. Lists can be viewed by Manufacturer,
by Device Name or by stepping through all Devices one at a time. Use the
soft key controls to move through the list. Pressing the key changes soft key definitions
Down
and
Up
to
PgUp
and
PgDn.
To quickly advance to the next page of a list, press the
PgDn
soft key. To retreat to the
prior page, press the
PgUp
soft key. Once engaged the
PgUp
and
PgDn
soft keys remain active until the
Up
or
Down
soft keys or is pressed again.
2 List / Edit Configs:
This screen lists all stored HART configurations by Tag Number. The
configurations stored enable fast commissioning of replacement devices,
cloning of existing systems, or re-configuring for changes in process
conditions or batch runs. Any configuration in the list can be sent to
another HART device of the same manufacture and model. The display
can show 20 character tag numbers. Truncated tags are listed if more than
20 characters are used. Moving the cursor down to the tag of interest and
pressing the
Select
soft key will provide a detailed information screen,
including full tag number up to 28 characters, for the tag of interest (see
example below, right).
