Protocol-specific data

HART
• Manufacturer ID: 17 (0x11)
• Device type code: 0x11C4
• Device revision: 1
• HART specification: 7
• DD revision: 1
• Device description files (DTM, DD) information and files at:
• www.endress.com
• www.fieldcommgroup.org
• HART load: min. 250 Ω
HART device variables (preset at the factory)
The following measured values are assigned to the device variables at the factory:
Primary variable (PV) parameter (Primary variable)
Secondary variable (SV) parameter (Secondary variable)
Tertiary variable (TV) parameter (Third variable)
Quaternary variable (QV) parameter (Quaternary variable)
1) The PV is always applied to the current output.
2) Point level detection is the initial state depending on the fork state (uncovered/covered) and the safety
function (MIN/MAX)
3) Sensor frequency is the oscillation frequency of the fork
4) Fork state is the fork state (Fork covered option/Fork uncovered option)
Choice of HART device variables
• Level limit detection
• Sensor frequency
• Fork state
• Sensor temperature
• Terminal current
The terminal current is the read-back current on terminal block. Visibility depends on
order options or device settings
• Terminal voltage
Visibility depends on order options or device settings
Supported functions
• Burst mode
• Additional transmitter status
• Device locking
