HES HART Device Status
HART device status messages are produced on the data being processed through the system
(i.e. data quality stamps, channel and field device status registers).
Field Device Status
The HES and field devices all produce a Field Device Status byte as defined by the HART
standard.
The field device status bytes are available on the ‘Field Device HART Status’ web page (see
figure 5.10) and can also be found in the MODBUS registers (see MODBUS registers section
for locations).
The HES Field Device Status byte is on the ‘HES HART Status and Variables’ Webpage and in
the MODBUS registers.

Malfunction
The device detected a serious error or failure that
compromises HES device operation.
Additional Status
The HES and field devices all produce Additional Status bytes (25 maximum) as defined by the
HART standard.
If configured and available, the field device additional status bytes are on the ‘Field Device
HART Status’ webpage web page (see figure 5.10) and can also be found in the MODBUS
registers (see MODBUS registers section for locations).
