Introduction

The 1066 transmitter can communicate with a HART host using HART Revision 5 or HART Revision
7. The revision of HART used by the 1066 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. If HART Revision
7 can be used with the host, it does offer a number of advantages over Revision 5, including long tag
name, time stamped data, and measurement status, and enhanced burst mode.
When haRT 5 is chosen, the Device Revision of the 1066 is Device Revision 1; when haRT 7 is chosen
the Device Revision is Revision 2 (or greater). 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 1066.
A single HART 5 (Device Revision 1) or HART 7 (Device Revision 2 or greater) DD (Device
Description) is used for all model codes of the 1066, which include the pH/ORP, conductivity,
oxygen, chlorine, and ozone transmitters. All 1066 transmitters have the same HART device
identification, as outlined below:
