10 Signal Characterizer (SGCR)
Function Block
The Signal Characterizer (SGCR) function block characterizes or
approximates any function that defines an input/output relationship.
The function is defined by configuring as many as twenty X,Y
coordinates. The block interpolates an output value for a given input
value using the curve defined by the configured coordinates. Two
separate analog input signals can be processed simultaneously to give
two corresponding separate output values using the same defined
curve.
The SGCR block supports signal status propagation. There are no
standard alarms in this function block. Custom alarms are supported.
Figure 10-1 illustrates the internal components of the SGCR function
block, and Table 10-1 lists the system parameters. The block correlates
the input IN_1 to the output OUT_1 and the input IN_2 to the output
OUT_2 according to the configured curve. You can configure the curve
by defining as many as twenty pairs of X,Y values in the CURVE_X and
CURVE_Y parameters. The CURVE_X array defines the input values
(X1 to X20) and the CURVE_Y array defines the output values (Y1 to
Y20).

IN_1 and IN_2 = The input values to the block.
OUT_1 = The output associated with IN_1.
OUT_2 = The output associated with IN_2.
