It’s rare to find a HART device in a FOUNDATION Fieldbus network because most HART devices have FF versions to provide easier integration than a converter or gateway. But if you end up needing this kind of setup, a HART gateway will get you there.
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. But if you already have the device, get the gateway.
This list gives you a few options for HART to FF converters:
