D Burst Command—This defines which HART command is configured for burst reporting. There are three options to
choose from. When using a TriLoop, select the third option.
- Analog Input (Command 1)
- Loop Current / Travel (Command 2)
- Loop Current / PV / SV / TV / QV (Command 3)
Note
Access to information in the instrument is normally obtained through the poll/response of HART communication. The Field
Communicator or the control system may request any of the information that is normally available, even while the instrument is in
burst mode. Between each burst mode transmission sent by the instrument, a short pause allows the Field Communicator or
control system to initiate a request. The instrument receives the request, processes the response message, and then continues
“bursting” the burst mode data.
Burst mode will be automatically disabled during diagnostics tests such as Valve Signature.
Alert Setup
Field Communicator Configure > Alert Setup (2‐3)
An alert is a notification that the instrument has detected a problem. A shutdown is an action that the instrument
takes to drive the air output to the Zero Power Condition as per figure 3‐2. Some alerts can be configured to shutdown
the instrument. Refer to table 3‐9 for default alert and shutdown settings.
Alerts may be enabled or disabled with the instrument In Service, Out of Service, Protected, or Not Protected.
However, the instrument must be Not Protected to enable or disable a shutdown. Alerts are not processed when a
diagnostic is in progress.
If shutdown is enabled, and the alert is active, the instrument will latch in the shutdown state until power to the
instrument is cycled and the alert has cleared. While in the shutdown condition, HART communication will continue if
the instrument remains powered.
