Select 

Online Setup

 from the MFC Main navigation screen to initiate the multi-drop poll.  If the “No 

Devices Found” message is received, then the loop connections to the MFC should be carefully checked. 
 
If an operating HART device with address zero (0) is connected to the MFC but the  “Device  0  Not Found” 
notification is received, the loop connections to the MFC should be carefully checked. 
 
Make sure all connections are correct and secure.  Check for shorts, open circuits and multiple grounds.   
 
Determine if the loop resistance is greater than 250

 and less than 1100

s.  If less than 250 

 then use the 

supplied 250 

 load resistor in series with the loop (see diagram HART Connections section).   

 
If communication is still not established, check the 

List / Show DOFs

 menu under 

Offline Menu

.  Check 

the list for the presence of the “Generic” DOF under the manufacturer name “Meriam.”  If “Generic” is 
found, then HART communication is possible when the device is properly wired and connected to the MFC 
(see connection troubleshooting details above). 
 
When the message “Generic” is displayed after connecting to a HART device there are two possible causes: 

1)  No device specific DOF for that device is currently installed in MFC memory.  Check the Meriam 

Download Site for availability of the DOF needed by clicking on the Download Site button at 

www.meriam.com

 and entering the User Name and Password provided with MFC shipment.  For 

download instructions, see the DOF Download Site Information section of this manual. 

2)  The Meriam DOF “Device Library” is missing or has become corrupted.  Without this DOF, the 

MFC may not recognize a connected device.  Check the 

List / Show DOFs

 menu option of 

Offline 

Menu

 

 
 

More Status Message 

HART device events (diagnostic flags) cause the MFC to display a “More Status Message” at the bottom 
of the display.  This message is a notice to the user that one or more diagnostic warnings are available in 
the Review Status menu option of the connected device.  Upon receipt of this message, enter the 

HART

 

mode and select Detailed Setup / Diagnostics – Service / Test – Status / View Status to retrieve the 
diagnostic information. 

 

Save / Send Configuration Functions 

HART device configurations may be saved to MFC memory or sent from MFC memory to a HART 
device in all MFC model numbers.  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: 
 

1.  Press the Document key          on the MFC for the  

screen shown at right.  Then select the “Save/Send  
Configs” menu option to launch a HART communi- 
cation poll and use the Save / Send options. 
 

2. 

Use the Save / Send menu option within the HART  
device’s standard menu.   The MFC would be in  
Online mode in this case.  Save / Send is normally

  

found under the “Device Setup” menu option on the 
initial HART display for the device.
