SENSOR TRANSDUCER
BLOCK
NOTE
When the engineering units of the XD_SCALE in the associated AI Block are
selected, the engineering units in the Transducer Block change to the same
units. THIS IS THE ONLY WAY TO CHANGE THE ENGINEERING UNITS IN
THE SENSOR TRANSDUCER BLOCK.
Damping The damping parameter in the Transducer Block may be used to filter
measurement noise. By increasing the damping time, the transmitter will have
a slower response time, but will decrease the amount of process noise that is
translated to the Transducer Block Primary Value. Because both the LCD and
AI Block get input from the Transducer Block, adjusting the damping
parameter will effect the values passed to both blocks.
NOTE
The AI Block has it's own filtering parameter called PV_FTIME. For simplicity,
it is better to do filtering in the Transducer Block as damping will be applied to
primary value on every sensor update. If filtering is done in AI block, damping
will be applied to output every macrocycle. The LCD will display value from
Transducer block.

RB.DETAILED_STATUS Description
Sensor Transducer block error. Active when any SENSOR_DETAILED_STAUS bit is on
Manufacturing Block integrity error The manufacturing block size, revision, or checksum is
wrong
Hardware/software incompatible Verify the manufacturing block revision and the
hardware revision are correct/compatible with the
software revision.
Non-volatile memory integrity error Invalid checksum on a block of NV data
ROM integrity error Invalid application code checksum
Lost deferred NV data Device has been power-cycled while non-volatile writes
were being deferred to prevent premature memory
failure, the write operations have been deferred.
NV Writes Deferred A high number of writes has been detected to
non-volatile memory. To prevent premature failure, the
write operations have been deferred.
