Benefits of multidrop communication

Field Network Q&A

I heard that I can have a multidrop installation of the wirelessHART adapter. Could you explain multidrop communication and the benefits?

Expert’s answer: Benefits of multidrop communication

Thinking of using multidrop communication for your wirelessHART adapter? You’re in the right place.

With a 4-20mA setup, the HART protocol connects with a handheld or laptop to configure, diagnose, or calibrate devices. Although the HART doesn’t need communication with the control system, you can have a digital connection through a HART input/output (IO).

Now, a multidrop installation connects devices to a control system, allowing field communication with an IO. In fact, a multidrop can connect up to 15 devices on the same pair of cables. You also don’t have to deal with 4-20mA variation anymore, only the HART communication.
