Device Diagnostic Mapping
This table shows the bit mapping of RB_x_ACTIVE and RB_EXTENDED_ACTIVE parameters with the relating error name and
NAMUR NE107 category.
– Bit x° = Error conditions that can be Masked from RB_DIAGNOSIS_MASK
– Bit x* = Error conditions that can be simulated from RB_DIAGNOSIS_SIMULATION
Cat. Error
RB_fail / maintenance / offspec / check_ACTIVE
(indexes 42, 43, 44, 45)
RB_EXTENDED_ACTIVE (index 47)
Bit 0*
Sensor Invalid Bit 1
The transducer is not able to generate a valid
signal due to one of the following
conditions (see RB_EXTENDED_ACTIVE)
Bit 0*
The primary signal of the sensor is no longer
available
Sensor Memory Fail Bit 2*
The data in the sensor memory are corrupted
precluding the correct functionality of the
device
Bit 1*
The sensor and the connected electronics are
incompatible
Memory Failure Bit 3*
The device data loaded at the start up are cor-
rupted precluding the correct functionality of
the device
P-dP Sensor Fail Bit 4*
The sensor signal value is incorrect due to a
mechanical failure i.e. Loss of fill fluid from the
cell; ruptured diaphragm, broken sensor…
Static Pressure Sensor Fail Bit 5*
The sensor signal value is incorrect due to a
mechanical failure i.e. The circuitry for the sam-
pling of the static pressure has failed... Valid for
Differential pressure models
Sensor Temperature Fail Bit 6*
The circuitry for the sampling of the
temperature has failed. The measurement
accuracy is decreased more than the accept-
able error
Pressure Overrange Bit 7*°
The Pressure is outside the overpressure limit
and risk to damage the sensor
P-dP Out Of Limit Bit 8*°
The measured Process Pressure is outside the
sensor limits and no longer representing the
true applied process value
Static Pressure Out Of Limit Bit 9*°
The measured Static pressure is above its
operational limit
Input Simulation Active Bit 10°
The Input Simulation function is Active At
least one of these variables is simulated
Bit 2*
The Pressure Value produced in output is cal-
culated starting from a simulated input
Bit 3*
The Static Pressure Value produced in output
is calculated starting from a simulated input
Bit 4*
The Sensor Temp Value produced in output is
calculated starting from a simulated input
Sensor Temperature Out Of
Limit
Bit 11*°
The measured sensor temperature is out-
side of its operational limits
Max. Working Pressure
Exceeded
Bit 12*°
The measured Static Pressure is higher than
the acceptable mechanical limit of the pro-
cess connection elements.
Primary Variable Out of Range Bit 13*°
Process value is outside its High or Low
working range
