TAG: “FTB”
0
Information, such as Block Tag, DD Revision and Execution
Time, relating to this block
2301
ST_REV
–
–
1
This parameter expresses the revision level of the transducer
block setting parameters. This revision is updated when the
setting value is changed. This parameter is used, for
example, to investigate if parameters have been changed.
2302
TAG_DESC
AUTO
2
Universal parameter for storing comments to describe the
content of tags
2307
UPDATE_EVT
–
–
7
Indicates the content of an event when an update event has
occurred.
2308
BLOCK_ALM
–
–
8
Indicates the content of an error that has occurred in the
block.
2309
TRANSDUCER
_DIRECTORY
–
–
9
This parameter is for storing the index of the transducer to be
included in the transmitter.
2310
TRANSDUCER
_TYPE
–
104 (Standard
Flow with Calibration)
10
Indicates the type of transmitter.
2312
COLLECTION
_DIRECTORY
–
–
12
Stores the index of important parameters in the transducer
block and the item ID of the corresponding DD.
2316
FLOW_VALUE
_DECIMAL
–
0
16
Indicates the number of digits past the decimal point of the
flow value.
2317
FLOW_VALUE
_FTIME
O/S
0
17
Indicates the primary filter time constant (unit: seconds) of the
flow value.
2318
DIFF_
PRESSURE
–
–
18
Indicates the differential pressure value used in the flow
calculation and its status.
2320
STATIC_
PRESSURE
–
–
20
Indicates the static pressure value used in the flow
calculation and its status.
2321
STATIC_
PRESSURE_UNIT
O/S
1545(MPaa)
21
Sets the unit of the static pressure value.
2322
EXT_
TEMPERATURE
–
–
22
Indicates the external temperature value used in the flow
calculation and its status.
2323
EXT_
TEMPERAURE_UNIT
O/S
1001(
°
C)
23
Sets the unit of the external temperature value.
2324
FLOW_
CALCULATION_
MODE
O/S
0
24
Switches the flow calculation mode.
0: Auto Compensation Mode
1: Basic Mode
2314
FLOW_VALUE
–
–
14
Indicates the flow value and its status.
2319
DIFF_PRESSURE_UNIT
O/S
1133(kPa)
19
Sets the unit of the differential pressure value.
2315
FLOW_VALUE_UNIT
–
1324: kg/h
15
Indicates the unit of the flow value.
2303
STRATEGY
AUTO
1
3
Universal parameter intended for use when the host system
separates the function blocks
2305
MODE_BLK
AUTO
AUTO
5
This universal parameter expresses the operation mode of
the block, and comprises the Actual mode, Target mode,
Permit mode, and Normal mode.
2311
XD_ERROR
–
–
11
Stores the most important error among the errors currently
occurring in the transducer block.
When “0” is stored, this means that no errors are occurring.
2306
BLOCK_ERR
–
0x0000
6
Indicates the error state relating to the self block.
2304
ALERT_KEY
AUTO
1
4
This is one of the universal parameters and is key information
for identifying where an alert has occurred. Normally, the host
system identifies specific area in a plant covered by a specific
operator, and this information is used for selecting only the
required alert.
2313
FLOW_VALUE
_TYPE
–
1
13
Indicates the type of flow.
1: Mass flow
2: Volume flow
3: Standard volume flow
