XD ERROR Description
0No 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.
SENSOR CONFIG
STRUCTURE
Parameter Description
SENSOR_MODE Disables or enables a sensor for configuration.
SENSOR_TAG Sensor description.
SERIAL_NUMBER Serial number for the attached sensor.
SENSOR Se nsor 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.
