Dynamic HART® variables
16 Dynamic HART
®
variables
The HART
®
specication denes four dynam-
ic variables consisting of a value and an en-
gineering unit. These variables can be as-
signed to device parameters as required. The
universal HART
®
command 3 reads the dy-
namic variables out of the device. This al-
lows manufacturer-specic parameters to al-
so be transferred using a universal com-
mand.
In the TROVIS SAFE3730-6 Positioner, the
dynamic variables can be assigned in the
Device settings folder (> Positioner > HART
communication) as listed in uTable 5:
Device settings > Positioner > HART
communication

Ambient pressure, Signal pressure p out, Supply
pressure, Flow rate, Differential pressure, All
active errors
− Secondary variable assignment: Set point,
Direction of action set point, Set point after
transit time specication, [Valve position], Set
