HART on PROFIBUS

The PROFIBUS specification provides an open solution for incorporating HART

in PROFIBUS systems specifically. Here, the HART protocol is taken into

account in the specification as a PROFIBUS profile, which is also referred to as

"HART on PROFIBUS" for short.

This solution includes the use of the PROFIBUS communications mechanisms

without change to the PROFIBUS protocol and services, the PDUs or the state

machines and functional characteristics.

The HART client application is integrated within a PROFIBUS master and the

HART master within a PROFIBUS slave, the latter serving as a multiplexer and

handling the communication with the HART devices.
