Usually, you have many ways to set up field devices. These methods often depend on the model and vendor. Sometimes it can be difficult to figure out how to use a HART communicator but don’t worry, we will help.
You can also find devices where you can navigate the setup menu using these buttons. Still, other devices offer a local display with push buttons or a touchscreen.

How to use a HART communicator
You can use a HART communicator, or handheld, to connect with HART field devices. If the device doesn’t have HART communication protocol, some communicators can also use FOUNDATION Fieldbus or PROFIBUS PA.
If you use a HART communicator, then you definitely need device description (DD) files. These files tell the handheld how to correctly interpret the data from the field device.
Usually, when you buy a new HART communicator, it has a bunch of DDs installed in the database. However, if you don’t have the right version of the file, you’ll need to update the database, an often unpleasant procedure. You may also need a license for your update.
Fortunately, vendors have begun pitching new handhelds that don’t need licenses or complex procedures for updating. So keep an eye out for those.
Anyway, if you have the DD for your device, you can connect to it using your HART communicator. Also, you need a 250-ohm resistor on hand. You can read more about that here.
