List / Edit Configs:

   

Lists all stored HART configurations by Tag Number. Once a 
desired tag is located with the cursor, pressing the 

Select 

soft key 

displays header information to help the user confirm the identity 
and origin of the configuration. Pressing 

Select 

again opens the 

configuration for review and editing as needed. Any configuration 
in the list can be sent to another HART device of the same 
manufacture and model number.  This feature enables fast 
commissioning of replacement devices, cloning of existing 
systems, or re-configuring for changes in process conditions or 
batch runs.  New entries to this list are loaded to the bottom of the 
list.  If multiple entries for one device are shown, the most recently 
saved configuration is always listed last. 
 
Entries in this list may have been saved directly from a connected HART device, created in the MFT using 
the 

Create Configs

 function, copied from another configuration and renamed, or created by editing an 

existing file. MFT will also list configurations downloaded from the separately available Meriam Device 
Management System software (see www.meriam.com for more information).    

 

 

Create Configs:   

The 

Create Configs

 function allows the user to configure a HART device file in Offline Mode for sending to 

the intended device later when connected in the Online Mode.  Use the soft key controls to move through 
the list and select the device model number required.  The menus prompt the user to make the necessary 
configuration selections, tag the file for later retrieval and use, and edit configuration lines as required.  This 
function can be locked out.  See the Lockout Section of this manual for more information. 

 

Delete Individual Configs / Clearing Configuration Memory: 

Individual stored Configurations may be deleted with MFT 

Del

 soft 

key functions (see example at right).  A delete confirmation screen is 
provided to prevent unintended deletions. The 

Del

 key only hides the 

record from the MFT screen; it does not clear memory space.   
 
To clear 

all

 configurations from memory (including active and hidden  

configs), enter the 

HART Offline Menu Screen

 and select the 

Delete All Configs 

option.  The MFT will ask “Delete ALL Configs…  

ARE YOU SURE???”  Select 

Yes

 to clear 

all

 stored configurations 

from memory. 

 
 
 

HART ONLINE MODE 

Once a HART device is located, the MFT enters the 

Hart Device Online Screen 

as shown below. The word 

“Hart” appears in the top left of LCD. The     symbol will “flash” when HART communications have been 
established. 

 

Note:  The screen at right illustrates a Rosemount 1151 rev. 
5 HART display. Screen configuration may vary depending 
on the HART device connected.  For more information, 
please refer to the owner’s manual for the HART device 
under test.
