Let’s see if you should choose HART over FOUNDATION Fieldbus. It’s rare to find a HART device in an FF network because most HART devices have FOUNDATION Fieldbus versions to provide easier integration than a converter or gateway.

Connecting a HART device to a Fieldbus network using a gateway

There are a few products on the market that convert HART to Fieldbus. The converter or gateway will work as a master for the HART signal from the field devices and as a slave to the Fieldbus network, sending process values and diagnostics to your control system.

In my opinion, if the device has a FOUNDATION Fieldbus version, you should use it. It’s easier than installing a converter or gateway.

This list gives you a few options for HART to FF converters:
