Parameter Description
DEAD BAND_BYPASS
This parameter is used to enable the zero cutoff.
{ 1, “True” }
{ 0, “False” }
EEPROM_FLAG
This parameter is used to indicate EEPROM saving process.
{ 0, “False” }
{ 1, “True” }
FACTORY_CURVE_BYPASS
This parameter is used to enable factory characterization curve.
{ 85, “Disable” }
{ 170, “Enable and Backup Cal” }
{ 4010, “Disable and Restore Cal” }
{ 61440, “Disable or Allows to enter the points” }
FACTORY_CURVE_X This parameter contains input points of factory characterization curve.
FACTORY_CURVE_Y This parameter contains input points of factory characterization curve.
FACTORY_CURVE_LENGTH This parameter contains the number of points of factory characterization curve
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.
LIN_TYPE
Linearization – Type:
0 – No Linearization
1 – User Defined Table
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.
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.
MAX_TEMPERATURE Holds the maximum temperature. A write access to this parameter resets to the momentous value.
MIN_TEMPERATURE Holds the minimum temperature. A write access to this parameter resets to the momentous value.
ORDERING_CODE Indicates information about the sensor and control from production factory.
POLYNOMIAL_VERSION Indicates the polynomial version.
PRESS_LIN_NORMAL Indicates the Linear Normalized Pressure.
PRESS_NORMAL Indicates Normalized Pressure.
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 pressure device.
0: Pressure
1: Flow
2: Level
3: Volume
4-127: reserved
> 128: manufacture specific
PRIMARY_VALUE_UNIT
This parameter contains the engineering units index code for the primary value.
See explanation about Primary_Value_Unit.
PROCESS_CONNECTION_MATERIAL Not used.
PROCESS_CONNECTION_TYPE
Not used.
SCALE_IN
This is the input conversion of the Pressure into SECONDARY_VALUE_2 using the high and low
scale. The related unit is the SECONDARY_VALUE_1_UNIT.
SCALE_OUT
This is the output conversion of the linearized value using the high and low scale. The related unit
is the PRIMARY_VALUE_UNIT.
SECONDARY_VALUE_1 This parameter contains the Pressure value and status available to the Function Block.
SECONDARY_VALUE_1_UNIT This parameter contains the pressure 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.
