Parameter
Description
BACKUP_RESTORE
This parameter allows to save and to restore data according to factory and user calibration
procedures. It has the following options:
1,
"Factory Cal Restore",
2,
"Last Cal Restore",
3,
"Default Data Restore",
4,
"Shut-Down Data Restore",
11,
"Factory Cal Backup",
12,
"Last Cal Backup",
14,
"Shut-Down Data Backup",
0,
"None".
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.
CAL_POINT_HI
This parameter contains the highest calibrated value. For calibration of the high limit point you
give the high measurement value (pressure) 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 (pressure) to the sensor and transfer this point as LOW to the
transmitter. Unit derives from SENSOR_UNIT.
LIN_TYPE
Linearization Type:
0
– No Linearization
10
– Square Root
LOW_FLOW_CUT_OFF
This is the point in percent of flow till that the output of the flow function is set to zero. It
is used for suppressing low flow values.
FLOW_LIN_SQRT_POINT
This is the point of the flow function where the curve changes from linear to square root
function.
The input has to be done in percent of flow.
MAINT_DATE
The date of last maintenance.
EEPROM_FLAG
This parameter is used to indicate EEPROM saving process.
FACTORY_GAIN_REFERENCE
Factory calibration reference value.
MAIN_BOARD_SN
This is the main board serial number.
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.
ORDERING_CODE
Indicates information about the sensor and control from production factory.
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
: manufacturer specific
PRIMARY_VALUE_UNIT
This parameter contains the engineering units index code for the primary value. In this case the
unit code is mA (1211).
SECONDARY_VALUE_1
This parameter contains the current value and status available to the Function Block.
SECONDARY_VALUE_1_UNIT
This parameter contains the current units of the SECONDARY_VALUE_1. In this case the unit
code is mA (1211).
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. In this case the unit code
is % (1342).
SECONDARY_VALUE_2_UNIT
This parameter contains the units of the SECONDARY_VALUE_2 defined by the manufacturer. In
the this case the unit code mA (1211).
