Burst mode go!

Q&A System Integration

Can you explain burst mode to me? I have a field panel device, and I want to convert the HART signal to three-wire analog output. But for that, I need to configure the burst mode on the field device. Why do I need to do that?

Expert’s answer: Burst mode on field panel device

Why wouldn’t you want to do that? I’d activate it just because it sounds cool! I wish I could operate in burst mode!

Seriously though, you want it on because the converter needs to read the HART values from your field device. If you enable the burst mode, it’ll allow your device to send that data.

First, you have to set the burst mode on the device. You can use the display or handheld, whichever floats your boat. Then pick a card, any card (and by card I mean variable). Thus and so, the converter will catch the HART data, wave its wand, and convert it to analog outputs for the variable(s) you selected.

Because we love you, a quick tip before we dash: You can also use the burst mode when you want to send process data by wirelessHART using a wireless adapter. Nifty, huh?

These companies have a broad range of HART converters:

HART – The best PAM application
We have HART field devices, but we only get the analog signal from the field! How should we upgrade the system to read the diagnostics? With PLC cards or a multiplexer or maybe a wireless adapter?
HART communication: Viator Bluetooth interface

I have an AMS suite device manager, and I would like to know if can I use the Viator Bluetooth with my software? Do you know about that?

HART theory
Could you explain how it’s possible to send a digital communication through an analog signal?

HART Communicator: When to Use
I have a question about HART communicators. Can you help? When we have a local configuration, when do we use the HART communicator?
