Configuration and Diagnostics
This document will guide you through burst configuration and diagnostics using AMS Device Manager. Burst can be
configured the same way using the 475 Field Communicator. Refer to the appropriate instruction manual
[D103391X012 (4310) or D103392X012 (4320)], available from your Emerson Process Management sales office, or
www.Fisher.com, for the Field Communicator menu trees.
Access burst configuration by selecting the Broadcast Information tab from Configure, Manual Setup.
For each Burst Message that represents a HART
the following menu items are available: Enabled/Disabled, Message Content, Content Details, Trigger Details, Update
Details.
In each burst message configuration menu, the following items appear:
Enabled / Disabled—select On (WirelessHART
Off to disable this burst message and release bandwidth allocation back to the network.
Message Content—choose between:
Primary Variable (HART command 1)
PV %Range, Loop Current (command 2 - not recommended but available if a control system requires it)
Dynamic Variables, Current (command 3)
Selected Device Variables (command 9)
Additional Device Status (command 48)
Emerson Specific (command 178), (Press the HELP key for explanation)
Content Details—appears only if selected Message Content is user-configurable (commands 3, 9, and 178).
You may assign the desired device variables to individual slots in the message. In the 'Selected Device Variables'
choice, the first slot assignment becomes the trigger variable when a trigger mode other than Continuous or
On-Change is used.
Trigger Details—select the trigger mode (Continuous, Windowed, Rising, Falling, or On-Change).
Trigger class and units must also be selected when trigger mode is not Continuous. (Press the HELP key while at the
Trigger Details menu item in the Burst Message menu for guidance).
Update Details—this menu structure varies based on the Message Content and Trigger Details selections.
The HELP key provides guidance for each parameter. For Continuous trigger mode, only the Update Rate is presented.
For On-Change, a Default Update Rate is added. For Windowed, Rising, and Falling, there is also a Trigger Level to
configure. When the mode is other than Continuous, there is an option to enable and configure Delayed Triggering,
which allows the device to sample the trigger variable faster than the Default Update Rate so that transitions are less
likely to be missed.
