ACTIVE (indexes 47, 48, 49, 50)
PRTB NormalMode = AUTO and PRTB
Bit 0
TargetMode != AUTO
The transducer is not able to generate a
valid signal due to one of the following
Bit 1
conditions (see RB_EXTENDED_ACTIVE)
The data in the sensor memory are
corrupted precluding the correct
Bit 2
functionality of the device
The device data loaded at the start up are
corrupted precluding the correct
Bit 3
functionality of the device
The sensor signal value is incorrect due to a
mechanical failure i.e. Loss of fill fluid from
Bit 4
the cell; ruptured diaphragm, broken
sensor...
The sensor signal value is incorrect due to a
mechanical failure i.e. The circuitry for the
sampling of the static pressure has failed...
Bit 5
Valid for Differential pressure models
The circuitry for the sampling of the
temperature has failed. The measurement
accuracy is decreased more than the
Bit 6
acceptable error
The Pressure is outside the overpressure
Bit 7
limit and risk to damage the sensor
The measured Process Pressure is outside
the sensor limits and no longer representing
Bit 8
the true applied process value
The measured Static pressure is above its
Bit 9
operational limit
The Input Simulation function is Active At
Bit 10
least one of these variables is simulated
The measured sensor temperature is
Bit 11
outside of its operational limits
The measured Static Pressure is higher than
the acceptable mechanical limit of the
Bit 12
process connection elements.
Process value is outside its High or Low
working range
RB_EXTENDED_ACTIVE (index 69)
The primary signal of the sensor is no longer
Bit 0
available
The sensor and the connected electronics are
Bit 1
incompatible
The Pressure Value produced in output is
Bit 2
calculated starting from a simulated input
The Static Pressure Value produced in output is
Bit 3
calculated starting from a simulated input
The Sensor Temp Value produced in output is
Bit 4
calculated starting from a simulated input
