5.3.2 Parameters of AI Function Block
Relative
index
Parameter name R/W Data format Description
0 Block Header Information about this block
1 ST_REV R TYPE_U16/2
The revision level of the static data associated with the function
block. The revision value will be incremented each time a static
parameter value in the block is changed.
2 TAG_DESC W TYPE_OCT_STRING/32 A parameter to describe a comment about the content of the tag
3 STRATEGY W TYPE_U16/2
A parameter available for high-level system to group or identify
the function block. This data is not checked or processed by the
block.
4 ALERT_KEY W TYPE_U8/1
Identification number of the plant unit. This information may be
used for sorting alarms, etc.
5 MODE_BLK.TARGET W TYPE_ENUM/1
A parameter to set the mode of function block. Only one of the
supported modes can be selected.
6 MODE_BLK.ACTUAL R TYPE_ENUM/1
The current mode of the block. (May differ from TARGET based
on operating conditions.)
7 MODE_BLK.PERMITTED W TYPE_ENUM/1 This is the mode supported by the function block.
8 MODE_BLK.NORMAL W TYPE_ENUM/1 This is the mode set at normal operation condition.
9 BLOCK_ERR R TYPE_ENUM/2
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.
10 PV.STATUS R TYPE_ENUM/1
Filtered measurement value and status that are assigned to this
block
11 PV.VALUE R TYPE_FLOAT/4
12 OUT.STATUS R TYPE_ENUM/1
Final output of measurement value and status that are assigned
to this block
13 OUT.VALUE W TYPE_FLOAT/4
14 SIMULATE.SIMULATE_STATUS W TYPE_ENUM/1
This parameter is associated with SIMULATE function.
Procedure to execute SIMULATE function:
Set SW2-2 on the FB-B board to "ON"
Set desired simulated alarm to SIMULATE_VALUE
Set ENABLE_DISABLE to Active
15 SIMULATE.SIMULATE_VALUE W TYPE_FLOAT/4
16 SIMULATE.TRANSDUCER_STATUS R TYPE_ENUM/1
17 SIMULATE.TRANSDUCER_VALUE R TYPE_FLOAT/4
18 SIMULATE.ENABLE_DISABLE W TYPE_ENUM/1
19 XD_SCALE.EU_100 W TYPE_FLOAT/4 Value equivalent to 100% of input scale from transducer block
20 XD_SCALE.EU_0 W TYPE_FLOAT/4 Value equivalent to 0% of input scale from transducer block
21 XD_SCALE.UNITS_INDEX W TYPE_ENUM/2 Unit of input scale from transducer block
22 XD_SCALE.DECIMAL W TYPE_I8/1 Placement of decimal point for input scale from transducer block
23 OUT_SCALE.EU_100 W TYPE_FLOAT/4
Relative output scale of XD_SCALE.EU_100 of this block. This
parameter must be configured if calculation (L_TYPE) setting of
the block is "Indirect".
24 OUT_SCALE.EU_0 W TYPE_FLOAT/4
Relative output scale of XD_SCALE.EU_0 of this block. This
parameter must be configured if calculation (L_TYPE) setting of
the block is "Indirect".
25 OUT_SCALE.UNITS_INDEX W TYPE_ENUM/2
Unit of output scale of this block. This parameter must be
configured if calculation (L_TYPE) setting of the block is
"Indirect".
26 OUT_SCALE.DECIMAL W TYPE_I8/1 Placement of decimal point for output scale of this block
27 GRANT_DENY.GRANT W TYPE_ENUM/1
Selection of an item (program, tuning, alarm, or local) which the
operator, a higher level device (HLD), or a local operator's panel
(LOP) is permitted to operate.
28 GRANT_DENY.DENY W TYPE_ENUM/1
The denied attribute is reserved for a monitoring application of
an interface device. This parameter cannot be changed by an
operator.
29 IO_OPTS W TYPE_ENUM/2
Optional functions for I/O of AI block. Only Low cutoff is available
for this device.
30 STATUS_OPTS W TYPE_ENUM/2
Optional functions for block processing of status.
This block supports: Propagate Fault Fwd, Uncertain if Limited,
Bad if Limited, and Uncertain if Man.
31 CHANNEL W TYPE_ENUM/2
This parameter sets the channel number of measurement data
input by transducer block. Standard assignments on this device
are: AI1; volume flow, AI2; mass flow, AI3; density, and AI4;
temperature (assignment can be reconfigured arbitrarily) .
32 L_TYPE W TYPE_ENUM/1
This parameter defines how the values sent to AI block from
transducer block is used for calculation. Direct: directly output
the input values, Indirect: values in different units are linearly
converted before output, Indirect Sq Root: not supported by this
device.
33 LOW_CUT W TYPE_FLOAT/4
This parameter sets low cut value of output. It is activated when
low cutoff is configured at IO_OPTS.
34 PV_FTIME W TYPE_FLOAT/4 This parameter configures filter (time constant) of output value
35 FIELD_VAL.STATUS R TYPE_ENUM/1
% value obtained by scaling input value from transducer block
with XD_SCALE
36 FIELD_VAL.VALUE R TYPE_FLOAT/4
