variables are derived from the associated HART 7
specification names.
Dynamic
variable Description
lc/val Loop current as a floating point value in mA.
pv/val Primary variable value as a floating point
number. The units in the data point are
derived from information returned by the
HART device.
sv/val Secondary variable value as a floating point
number. The units in the data point are
derived from information returned by the
HART device.
tv/val Tertiary variable value as a floating point
number. The units in the data point are
derived from information returned by the
HART device.
qv/val Quaternary variable value as a floating point
number. The units in the data point are
derived from information returned by the
HART device.
Description
Identifies the device.
Identifies the device-specific function or sensor for the data
stream. For example, hart1 corresponds to the sensor for a
device with HART protocol on Analog 4-20mA Current Loop 1.
