The OUTPUT is generated from the INPUTs according to the operation type selected. The output is always
limited to be within the range -300.00% to +300.00%.

IF(C) -A If INPUT C is not zero the OUTPUT is minus INPUT A, otherwise the
OUTPUT is the same as INPUT A.
ABS(A+B+C) The OUTPUT is set to the absolute value of INPUT A + INPUT B + INPUT C.
SWITCH(A,B)
OUTPUT
INPUT A
INPUT B
INPUT C
If INPUT C is zero the OUTPUT is
set to INPUT A, otherwise the
output is set to INPUT B
(A*B)/C The OUTPUT is set to (INPUT A * INPUT B) / (INPUT C). The algorithm
compensates for the remainder term.
A+B+C The OUTPUT is set to (INPUT A + INPUT B + INPUT C).
A-B-C The OUTPUT is set to (INPUT A - INPUT B - INPUT C).
B <= A <= C
OUTPUT INPUT A
INPUT B
INPUT C
The OUTPUT is set to the value of
INPUT A, limited to between a
maximum value of INPUT C and a
minimum value of INPUT B. If
INPUT B is greater than INPUT C
the output is undefined.
A>B+/-C
OUTPUT
INPUT A
INPUT B
INPUT C
The OUTPUT is TRUE if INPUT
A is greater than INPUT B +
INPUT C. The OUTPUT is FALSE
if INPUT A is less than INPUT B -
INPUT C.
Otherwise the OUTPUT is unchanged. In this way the block acts as a simple
comparator with a comparison level of INPUT B and a hysteresis band equal to
+/- INPUT C.
A>=B
OUTPUT
INPUT A
INPUT B
The OUTPUT is TRUE if INPUT
A is greater than or equal to INPUT
B, otherwise the OUTPUT is
FALSE.
ABS(A)>
ABS(B)+/-C
OUTPUT
INPUT A|
|INPUT B|
INPUT C
The OUTPUT is TRUE if the
magnitude of INPUT A is greater
than or equal to the magnitude of
INPUT B - INPUT C.
The OUTPUT is FALSE if the magnitude of INPUT A is less than the
magnitude of INPUT B - INPUT C. Otherwise the OUTPUT is unchanged. In
this way the block acts as a magnitude comparator with a comparison level of
INPUT B and a hysteresis band equal to +/- INPUT C.
ABS(A)>
=ABS(B)
OUTPUT
|INPUT A|
|INPUT B|
The OUTPUT is TRUE if the
magnitude of INPUT A is greater
than or equal to the magnitude of
INPUT B, otherwise the OUTPUT
is FALSE.
