266 Models - FOUNDATION Fieldbus
Idx Parameter Data Type Size Storage Description / Range / Selections / Notes
0 BLOCK_OBJ mix R Mix 62 In the Block Object data structure, there are different items describing the block characteristics. Execution period, Number of
parameters in the block, the DD Revision, Profile Revision, View Objects characteristics and so on
1 ST_REV R S U16 2 N
The revision level of the Static data associated with the Function Block. The revision level is incremented each time a static parame-
ter value (S – under Storage) in the block is changed.
2 TAG_DESC RW S O_STR 32 S The user description of the intended application of the block
3 STRATEGY RW S U16 2 S The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
4 ALERT_KEY RW S U8 1 S The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
5 MODE_BLK
TARGET RW
R DS-69 4
S AUTO / OOS The selectable modes by the operator.
ACTUAL R D The mode the block is currently in.
PERMITTED RW S AUTO / OOS The allowed modes the operator can select as Target
NORMAL RW S AUTO The common mode for the Actual.
6 BLOCK_ERR R S B_STR 2 D
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.
Bit 0 = Other
Bit 4 =Local Override
Bit 7 = Sensor Failure detected by this block/process variable has a status of BAD, Sensor Failure
Bit 15 = Out of Service
7 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
8 BLOCK_ALM RW R DS-72 13 D
The block alarm is used for all configuration, hardware, and connection failure or system problems in the block. The cause of the
alert is entered in the sub-code 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 sub-code has changed
9 TRANSDUCER_DIRECTORY R A U16 2 S Directory that specifies the number and starting indices of the transducers in the transducer block
10 TRANSDUCER_TYPE R S U16 2 S Identifies the transducer type. TN-016 – 100 = Standard Pressure with calibration
11 XD_ERROR R S U8 1 D Transducer block error sub-code
12 COLLECTION_
DIRECTORY
R A U32 4 S
Directory that specifies the number, starting indices, and the DD items IDs of the data collections in each transducer within a
transducer block
13 PRIMARY_VALUE_TYPE RW S U16 2 S Selects the type of measurement represented in PRIMARY_VALUE TN-016 - Changing has no calculation effect
14 PRIMARY_VALUE R R DS-65 5 D Pressure Process (PdP) in output from PRTB and input to the AI with Channel = 1
15 PRIMARY_VALUE_
RANGE
RW R DS-68 11 S
The High and Low range limit values, the engineering units code and the number of digits to the right of the decimal point Used as
input scaling for the production of the Scaled PV
16 CAL_POINT_HI RW S FLT 4 S
PdP Sensor Calibration point High value expressed in CAL_UNIT
17 CAL_POINT_LO RW S FLT 4 S PdP Sensor Calibration point Low value expressed in CAL_UNIT
18 CAL_MIN_SPAN R S FLT 4 D
PdP Sensor Calibration minimum Span value expressed in CAL_UNIT. When calibration is done, the two calibrated
points (high and low) must not be too close together.
19 CAL_UNIT RW S U16 2 S Calibration Unit.
Only Pressure Units are allowed
20 SENSOR_TYPE R S U16 2 S Type of Sensor
TN-016 – 121 = Pressure sensor unknown
21 SENSOR_RANGE R R DS-68 11 S The High and Low PdP physical sensor limits with the engineering units code (Press Only)
22 SENSOR_SERIAL_NUMBER R S V_STR 32 S Serial Number of the sensor
Block mapping
