Burst Mode Select: Burst mode is a communications option that allows a HART device to continuously
broadcast pre-selected information to a host device. The MFT does not use burst mode for its interface
with HART devices. Burst information is often used within a plant’s information technology framework. The
MFT can be used to set a device’s burst mode information and to initiate or terminate the Burst Mode
Select function. It does not display the burst mode variable.
To enter the Burst Mode Select option, use the Up or Down soft key to move the selection arrow to Burst
Mode Select, then press the Select soft key.
Press the Edit soft key, and use the Increase and Decrease soft keys to toggle the burst mode on or off.
Press Done when the desired option is displayed. The MFT will query if the new data should be saved.
Pressing Yes puts the MFT into the selected burst mode, and returns the MFT to the Hart Output main
menu screen. Selecting No leaves the device in the original “As found” burst mode and returns the MFT to
the Hart Output main menu screen.
Burst Mode communications are differentiated from normal HART communications with the filled heart
symbol displayed when communicating.
Burst Com Number: This register is used to select the information that will be continuously broadcast.
The selection will differ from device to device.
To enter the Burst Com Number option, use the Up or Down soft key to move the selection arrow to Burst
Com Number, then press the Select soft key.
The screen will display the currently selected output setting for the device. Press Back to return to the Hart
Output main menu screen if you do not wish to edit the settings.
To edit the current settings, press the Edit soft key. Use the Increase and Decrease soft keys to scroll
through the selections for that specific device.
Press Done when the desired selection is displayed. A prompt will appear: Save new data? Press the Yes
soft key to accept the new Burst Com Number changes. Pressing No returns the MFT to the Hart Output
main menu screen without saving changes to the device.
