8.1 Overview of the Device Description files (DTM)
To integrate the device via HART into FieldCare, a Device Description file (DTM) according
to the following specification is required:
Manufacturer ID 0x11
Device type (NMT81) 0xC3
HART specification 7.0
DD files For information and files see:

8.2 Measured variables via HART protocol
The following measured values are assigned to the device variables at the factory:
Device variable Measured value
Primary variable (PV)
1)
Liquid temperature
Product temperature
Water temperature
Secondary variable (SV) Vapor temperature
Tertiary variable (TV) Water level
Quaternary variable (QV) Liquid temperature
Product temperature
Vapor temperature
Water temperature
Water level
Tank level
Element temperature
Element resistance
Electronics temperature
Test resistance
Terminal voltage
Percent of range
Loop current
1) The PV is always applied to the current output.
The assignment of the measured values to the device variables can be changed in the
following submenu:
Application → HART output → HART output
