Documenting HART Configurations with Yokogawa DMS Software
The documentation functions of the YHC 4150X provide additional
functionality for use with the Yokogawa Device Management System
(DMS) software. DMS is a database product for complete device
management services including calibration documentation with the
Yokogawa YPC 4000 Series of multifunction calibrators and HART
configuration documentation with the YHC 4150X. Complete device
histories are maintained in the database. For HART devices these histories
can include as-found and as-left HART configuration data to complete this
important part of a
device’s history.
YHC 4150X Device Specific & Generic HART
®
Communications
Yokogawa supports a large and growing number of Device Specific DOFs (Device Object Files). For a current
listing of HART
®
devices with full Device Specific communication support, go to
http://dpcupdates.1911mptdofs.com/past.aspx
Information found there can be sorted by clicking on the column
headers (manufacturer name, model number, etc…).
To facilitate communication with HART devices that are not yet supported with Device Specific DOF files or
that do not require DOF files, the YHC includes Generic HART Communication capability. This allows the
user to communicate with any HART device using Universal and Common Practice commands to poll,
configure, and maintain HART devices. Specific functions supported include most polling, tagging, device
configuration and trim operations for analog outputs. Generic communications do not support Device Specific
commands for higher order HART functions (see the
HART
®
Commands
section of this manual or the User’s
Manual for the HART device of interest for more information on the three command levels).
Using Generic HART Communication
The YHC 4150X’s Generic HART Communication mode starts automatically when HART communication is
initiated with a device for which no Device Specific DOF (device object file) is stored in the handhelds flash
memory. When this occurs, line two of the display will indicate “Generic” and the device tag number.
The Document key on the YHC 4150X models will
save configurations in as-found or as-left categories as
selected by the user. These configuration files can be
uploaded later to DMS. When the
Save/Send Configs
menu
option is selected the YHC automatically polls for an online
device for subsequent user selections.
DMS can also be used as a configuration repository ready to
download stored device configurations for batch runs or
changes in operating requirements. New configurations can
be downloaded to YHC memory for later recall and use in the
field.
