Dynamic and Device Variables
Before setting up the HES, or incorporating the unit in your application, Moore Industries
suggests that all users take a few moments to become familiar with the different HART revisions
and variables available in their HART field devices.
Understanding How the HES Retrieves and Stores HART Field Device Data
HART Revisions
HART field devices are compliant to a certain HART revision. Most field devices released within
the last twenty years support HART revisions 5, 6 or 7. Each new revision of HART offers
different features and capabilities but all field devices, regardless of revision, still support
backwards compatibility with HART masters and handheld communicators. The HES, acting as
a HART master, communicates with all HART field devices that contain HART revision 5, 6 or 7.
It is important to verify what revision of HART the field device contains to ensure that the HES is
configured correctly.
HART Dynamic and Device Variables
HART devices can provide a significant amount of data in addition to the primary variable, which
is embedded onto the 4-20mA loop. In addition to diagnostic and status bits and bytes, there are
