Transducer Block Parameter Description
Parameter Description
SENSOR_VALUE
This parameter contains the raw sensor value. The uncalibrated measurement value from the
sensor. Unit derives from SENSOR_UNIT.
SENSOR_HI_LIM This parameter contains the sensor upper limit value. Unit derives from SENSOR_UNIT.
SENSOR_LO_LIM This parameter contains the sensor lower limit value. Unit derives from SENSOR_UNIT.
CAL_POINT_HI
This parameter contains the highest calibrated value. For calibration of the high limit point you give
the high measurement value to the sensor and transfer this point as HIGH to the transmitter. Unit
derives from SENSOR_UNIT.
CAL_POINT_LO
This parameter contains the lowest calibrated value. For calibration of the low limit point you give
the low measurement value to the sensor and transfer this point as LOW to the transmitter. Unit
derives from SENSOR_UNIT.
CAL_MIN_SPAN
This parameter contains the minimum calibration span value allowed. This minimum span
information is necessary to ensure that when calibration is done, the two calibrated points (high and
low) are not too close together. Unit derives from SENSOR_UNIT.
MAINT_DATE The date of last maintenance .
SENSOR_UNIT
This parameter contains the engineering units index code for the calibration values. In this case the
unit code is %.
SENSOR_SN The serial number of sensor.
TRIMMED_VALUE This parameter contains the sensor value after trim processing. Unit derives from SENSOR_UNIT.
PRIMARY_VALUE
This parameter contains the measured value and status available to the function block. The unit of
PRIMARY_VALUE is the PRIMARY_VALUE_UNIT.
PRIMARY_VALUE_TYPE This parameter contains the application of the device. (> 128: manufacture specific)
PRIMARY_VALUE_UNIT
This parameter contains the engineering units index code for the primary value. In this case the unit
code is % or mass or flow units (m

SECONDARY_VALUE_1 This parameter contains the value and status available to the function block.
SECONDARY_VALUE_1_UNIT This parameter contains the units of the SECONDARY_VALUE_1.
SECONDARY_VALUE_2
This parameter contains the measured value after input scaling and status available to the function
block. The related unit is the SECONDARY_VALUE_UNIT_2.
SECONDARY_VALUE_2_UNIT This parameter contains the units of the SECONDARY_VALUE_2 defined by the manufacturer
SCALE_IN
This is the input conversion of the current into PRIMARY_VALUE using the high and low scale. The
related unit is the PRIMARY_VALUE_UNIT.
SCALE_OUT
This is the output conversion value using the high and low scale. The related unit is the
PRIMARY_VALUE_UNIT.
MAX_SENSOR_VALUE
Holds the maximum process SENSOR_VALUE. A write access to this parameter resets to the
momentous value. The unit is defined in SENSOR_UNIT.
MIN_SENSOR_VALUE
Holds the minimum process SENSOR_VALUE. A write access to this parameter resets to the
momentous value. The unit is defined in SENSOR_UNIT.
SECONDARY_VALUE Indicates the temperature value and status.
SECONDARY_VALUE_UNIT The secondary value unit. In this case is always Celsius.
CAL_TEMPERATURE The calibration point for temperature sensor.
DIGITAL_HALL Digital value and status for Hall sensor.
DIAGNOSTIC_STATUS
Indicates the status for transducer block: 0x0001, “None”
0xfffe, “Ok”
0x0002, “Saturated Hall”
0xfffd, “Hall is Ok”
0x0004, “No mov. or no magnetic part”
0xfffb, “Magnet part is ok”
0x0008, “Burn out”
0xfff7, “No burn out”
0x0010, “Temperature out of work range”
0xffef, “Temp is Ok”
