1 2 3 4
0 BLOCK_
HEADER
Block
Tag=O/S
TAG: "SC" Information relating to this function block, such as
block tag, DD revision, and execution time
1 ST_REV - - - - - 2 2 2 2 The revision level of the set parameters associated
with the Signal Characterizer block
2 TAG_DESC Null Stores comments describing tag information.
3 STRATEGY 1 2 The strategy eld can be used by the high-level
system to identify function blocks.
4 ALERT_KEY 1-255 1 1 Key information used to identify the location at which
an alert has occurred
5 MODE_BLK 4 4 Mode of the Signal Characterizer block. O/S, Man,
and Auto are supported.
6 BLOCK_ERR 2 2 Indicates the error status of the Signal Characterizer
block in bit strings.
7 OUT_1 MAN 5 5 Outputs the result of the value of IN_1 corrected
using a line-segment function.
8 OUT_2 MAN 5 5 Outputs the result of the value of IN_2 corrected
using a line-segment function. It is also possible to
approximate the result using the inverse function of
the specied line-segment function. (This is used for
backward control.)
9 X_RANGE 100
0
1342
1
11 The engineering unit of variables corresponding to
the X-axis for display
10 Y_RANGE 100
0
1342
1
11 The engineering unit of variables corresponding to
the Y-axis for display
11 GRANT_DENY 2 The parameter used to check if various operations
have been executed.
The bits in the GRANT parameter corresponding to
various operations are set before being executed.
After the operations are complete, the DENY
parameter is checked for the setting of any bit
relating to the corresponding operation. If no bit
is set, it is evident that the operations have been
executed successfully.
12 IN_1 5 5 Input a signal to be corrected using a line-segment
function.
13 IN_2 5 5 Input a signal to be corrected using a line-segment
function.
14 SWAP_2 0:Initialized
1:No swap
2:Swap
1 Selector switch used to apply the inverse function to
line-segment approximation of IN_2 to OUT_2
15 CURVE_X Curve input points that determine inputs and
outputs.
The "x" points of the curve are dened by an array of
1 to 21 points with a monotone increase.
16 CURVE_Y Curve input points that determine inputs and
outputs.
The "y" points of the curve are dened by an array of
1 to 21 points.
If SWAP_2 is on, the elements of the curve must be
dened with a monotone increase or decrease.
17 UPDATE_EVT Indicates event information if an update event
occurs.
18 BLOCK_ALM Indicates alarm information if a block alarm occurs.
