HART device variables The measured values can be freely assigned to the device variables.
Measured values for PV, SV, TV and QV (first, second, third and fourth device variable)
• Sensor 1 (measured value)
• Sensor 2 (measured value)
• Device temperature
• Average of the two measured values: 0.5 x (SV1+SV2)
• Difference between sensor 1 and sensor 2: SV1-SV2
• Sensor 1 (backup sensor 2): If sensor 1 fails, the value of sensor 2 automatically
becomes the primary HART
• Sensor switching: If the value exceeds the configured threshold value T for sensor 1,
the measured value of sensor 2 becomes the primary HART
switches back to sensor 1 if the measured value of sensor 1 is at least 2 K below T:
sensor 1 (sensor 2, if sensor 1 > T)
• Average: 0.5 x (SV1+SV2) with backup (measured value of sensor 1 or sensor 2 in
the event of a sensor error in the other sensor)
Supported functions • Burst mode
• Squawk
• Condensed status
1) Not possible in the SIL mode, see Functional Safety Manual SD01632T/09
