TP302 – Operation, Maintenance and Instructions Manual
3.2
Supported Modes
OOS and AUTO.
BLOCK_ERR
The BLOCK_ERR of the transducer block will reflect the following causes:
Input Failure – When mechanic module is disconnected from main electronic board.
Out of Service – When the block is in OOS mode.
Primary_Value Status
The PRIMARY_VALUE status of the transducer block will reflect the following causes:
Bad::SensorFailure:NotLimited – When mechanic module is disconnected from main electronic
board.

Units Store Description
1 ST_REV Unsigned16 0 None S Indicates the level of static data.
2 TAG_DESC VisibleString Null Na S Description of Transducer Block.
3 STRATEGY Unsigned16 0 None S
This parameter is not checked and
processed by Transducer Block.
4 ALERT_KEY Unsigned8 1-255 0 None S Number of identification in the plant.
5 MODE_BLK DS-69 See Table O/S Na Mix
Indicates the operation mode of
Transducer Block.
6 BLOCK_ERR Bit String D
Indicates the status associated
with hardware or software in the
Transducer.
7 UPDATE_EVT DS-73 Na D It is the alert for any static data.
8 BLOCK_ALM DS-72 Na D
It is used for configuration, hardware
and others failures.
9 TRANSDUCER_DIRECTORY
Array of
Unsigned16
None N
It is used to select several Transduce
Blocks.
10 TRANSDUCER_TYPE Unsigned16 See Table 65535 E N
Indicates the type of Transducer
according to its class.
11 XD_ERROR Unsigned8 See Table 0 None D
It is used to indicate calibration
status.
12 COLLECTION_DIRECTORY
Array of
Unsigned 32
None S
Specifies the number of transducer
index into Transducer Block.
13 PRIMARY_VALUE_TYPE Unsigned16 See Table 65535 None S
Defines the calculation type for
Transducer Block.
14 PRIMARY_VALUE DS-65

INF
0 PVR D
It is the value and status used by
channel 1, 2 and 3.
15 PRIMARY_VALUE_RANGE DS-68 0-100% 100 PVR S
The High and Low range limit
values, the engineering unit code
and the number of digits to the
right of the decimal point to be
used for Primary Value.
16 CAL_POINT_HI Float +INF 100 CU S The highest calibrated value.
17 CAL_POINT_LO Float -INF 0 CU S The lowest calibrated value.
18 CAL_MIN_SPAN Float 5.0 % CU S
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.
19 CAL_UNIT Unsigned16 See Table % E S
The Device Description engineering
units code index for the calibration
values.
20 SENSOR_SN Unsigned32 0 to 2
32
0 S The sensor serial number.
21 SENSOR_CAL_METHOD Unsigned8 See Table Factory None S
The method of last sensor calibration
ISO defines several standard
methods of calibration. This
parameter is intended to record that
method, or if some other method was
used.
