Description
MODE_BLK Mix
Display of the current (
actual
), desired (
target
), possible (
permitted
) and
normal
modes of the Transducer Block. By writing a permitted value to the
target field, you can control the execution modes of the block. The following
block modes are allowed for the IFC090-FF Transducer Block:
Automatic Mode (AUTO)
In this mode, the transducer performs an automatic measurement update
and delivers it via its channels to connected input blocks (normally, the
integrated Analog Input Block)
Manual
(MAN)
Different from the AUTO mode, the block doesn’t perform an automatic
delivery of valid measurement values, but freezes its primary value to the
last one obtained in Auto mode. The
PRIMARY_VALUE
status switches
to
Uncertain:NonSpecific:Constant
.
Out of Service (OOS)
In this mode, the transducer stops measurement update and sets the
status of the measured value (
PRIMARY_VALUE
) to
BadOutOfService:NotLimited.
NOTE:
If the Resource Block is in mode Out of Service, also the block will remain in
this mode.
PRIMARY_VALUE R
The measured value and status available to the Function Blocks.
PRIMARY_VALUE_RANGE R
The high and low range limit values, the engineering units code and the
number of digits to the right of the decimal point to be used to display the
PRIMARY_VALUE.
PRIMARY_VALUE_TYPE R/W
Type of sensor. The IFC090-FF is of type ‘volumetric flow’ (101).
NOTE:
Even though this parameter is writable, it does not accept a value different
from ‘volumetric flow’ (101).
SECONDARY_VALUE R
Normally, the secondary value, is related to the sensor. Since the IFC090-FF
has no secondary value, this is fixed to status Bad:NonSpecific:NotLimited
with value 0.0.
SECONDARY_VALUE_UNIT R/W
Normally the units to be used for the
SECONDARY_VALUE
. Since the
IFC090-FF has no secondary value, this is fixed to the unit of the primary
value.
SENSOR_CAL_DATE R/W
Date of last sensor calibration. If this is set ‘01/01/84 00:00:00’ it means that
the last calibration was that after production of device.
SENSOR_CAL_LOC R/W
Location of last sensor calibration.
SENSOR_CAL_METHOD R/W
Method of last sensor calibration. In the context of the ISO defined standard
method of calibrations, KROHNE performed a ‘factory trim standard
calibration’.
SENSOR_CAL_WHO R/W
Name of the person responsible for the last calibration.
SENSOR_RANGE R
The high and low range limit values, the engineering units code, and the
number of digits to the right of the decimal point for the sensor. These values
are equal to the one given for PRIMARY_VALUE_RANGE.
SENSOR_SN R
Sensor serial number. Must be the same as on the nameplate of the device’s
housing.
SENSOR_TYPE R/W
Type of sensor. For IFC090-FF this is fixed: ‘Electromagnetic’ (102)
NOTE:
Even though this parameter is writable, it does not accept a value different
from ‘Electromagnetic’ (102).
