XD ERROR Description
0 No Error
17 General Error
An error has occurred that could not be classified as one of the
errors listed below.
18 Calibration Error
An error occurred during calibration of the device or a calibration
error has been detected during operation of the device.
19 Configuration Error
An error occurred during configuration of the device or a
configuration error has been detected during operation of the
device.
20 Electronics Failure An electronic component has failed.
22 I/O Failure An I/O failure has occurred.
23 Data Integrity Error
Indicates that data stored within the system may no longer be valid
due to non-volatile memory checksum failure, data verify after
write failure, etc.
24 Software Error
The software has detected an error. This could be caused by an
improper interrupt service routine, an arithmetic overflow, a
watchdog timer, etc.
25 Algorithm Error
The algorithm used in the transducer block produced an error. This
could be due to an overflow, data reasonableness.
Parameter Description
SENSOR_MODE Disables or enables a sensor for configuration.
SENSOR_TAG Sensor description.
SERIAL_NUMBER Serial number for the attached sensor.
SENSOR
Sensor Type and Connection. MSB is the sensor type and LSB is the
connection.
DAMPING
Sampling Interval used to smooth output using a first order linear filter.
A value entered between 0 and the Update_Rate, will result in a
damping value equal to the Update_Rate.
INPUT_TRANSIENT_FILTER
Enables or Disables the option for reporting fast changing sensor inputs
without temporary holdoff. 0 = Disable, 1 = Enabled.
RTD_2_WIRE_OFFSET
User entered value for constant lead-wire resistance correction in a
2-wire RTD and ohm sensor types.
ENG_UNITS The engineering units used for reporting measured sensor values.
UPPER_RANGE
The upper sensor limit for the selected sensor is displayed using
Units_Index sub parameter.
LOWER_RANGE
The lower sensor limit for the selected sensor is displayed using
Units_Index sub parameter.
