C.6 Average temperature transducer block
The Average Temperature Transducer block contains temperature measurement data and configuration
parameters.
Table C-14. Average Temperature Transducer Block Parameters
Index
Number
Parameter Description
1 ST_REV The revision level of the static data associated with the function
block. The revision value increments each time a static parameter
value in the block is changed.
2 TAG_DESC The user description of the intended application of the block.
3 STRATEGY The strategy field can be used to identify grouping of blocks. This
data is not checked or processed by the block.
4 ALERT_KEY The identification number of the plant unit. This information may
be used in the host for sorting alarms, etc.
5 MODE_BLK The actual, target, permitted, and normal modes of the block.
Target: The mode to “go to”
Actual: The mode the “block is currently in”
Permitted: Allowed modes that target may take on
Normal: Most common mode for target
6 BLOCK_ERR This parameter reflects the error status associated with the
hardware or software components associated with a block. It is a
bit string, so that multiple errors may be shown.
7 UPDATE_EVT This alert is generated by any change to the static data.
8 BLOCK_ALM The block alarm is used for all configuration, hardware, connection
failure or system problems in the block. The cause of the alert is
entered in the subcode field. The first alert to become active will
set the Active status in the Status parameter. As soon as the
Unreported status is cleared by the alert reporting task, another
block alert may be reported without clearing the Active status, if
the subcode has changed.
9 TRANSDUCER_DIRECTORY Directory that specifies the number and starting indices of the
transducers in the transducer block.
10 TRANSDUCER_TYPE Identifies the transducer.
11 TRANSDUCER_TYPE_VER
12 XD_ERROR A transducer block alarm sub code. Provides additional error codes
related to transducer blocks.
13 COLLECTION_DIRECTORY A directory that specifies the number, starting indices, and DD
Item ID’s of the data collections in each transducer within a
transducer block.
14 TEMPERATURE_UNIT Measurement Unit for all temperature parameters
15 LENGTH_UNIT Measurement Unit for all length parameters
16 TEMP_AVERAGE_LIQUID Average Liquid Temperature
17 STATUS_AVG_LIQUID Average Liquid Temperature Status
18 TEMP_AVERAGE_VAPOR Average Vapor Temperature
19 STATUS_AVG_VAPOR Average Vapor Temperature Status
20 TANK_TEMPERATURE Average Tank Temperature
