Functional Description
OUTPUT is generated from the inputs according to the operation type selected. The output is always limited to be within the range -32768.00 to
+32767.00.
Operation Description
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.
