Expert’s answer: HART over FOUNDATION Fieldbus
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 FF versions to provide easier integration than a converter or gateway to FF.
Nonetheless, there are a few products on the market that convert HART to FF. The converter or gateway will work as a master for the HART signal from the field devices and as a slave to the FF network, sending process values and diagnostics to your control system.
In my opinion, if the device has an FF 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:
