11.1 Introduction
The 56 can communicate with a HART host using HART Revision 5 or HART Revision 7. The
revision of HART used by the 56 can be selected using the keypad/display or a HART master
such as AMS or the 475 Handheld Communicator. The default version of HART is Revision 5.
Since some HART hosts cannot accommodate HART 7, the choice of HART Revision should
be based on the capabilities of the host, and should be chosen as a first step in configuration.
When HART 5 is chosen, the Device Revision of the 56 is Device Revision 1; when HART 7 is
chosen the Device Revision is Revision 2, or higher, for later revisions of the 56. The Device
Revision of the DD (Device Description) and install files for AMS and DeltaV used should be
the same as the Device Revision of the 56.
