Operation
Description
NOT(A)
OUTPUT
INPUT A
INPUT B
INPUT C
NOT(A)
If INPUT A is TRUE the
OUTPUT is FALSE,
otherwise the OUTPUT is
TRUE.
AND(A,B,C)
OUTPUT
INPUT A
INPUT B
INPUT C
AND(A,B,C)
If A and B and C are all
TRUE then the OUTPUT is
TRUE, otherwise the
OUTPUT is FALSE.
NAND(A,B,C)
OUTPUT
INPUT A
INPUT B
INPUT C
NAND(A,B,C)
If A and B and C are all
TRUE then the OUTPUT is
FALSE, otherwise the
OUTPUT is TRUE.
OR(A,B,C)
OUTPUT
INPUT A
INPUT B
INPUT C
OR(A,B,C)
If at least one of A or B or C
is TRUE then the OUTPUT
is TRUE, otherwise the
OUTPUT is FALSE.
NOR(A,B,C)
OUTPUT
INPUT A
INPUT B
INPUT C
NOR(A,B,C)
If at least one of A or B or C
is TRUE then the OUTPUT
is FALSE, otherwise the
OUTPUT is TRUE.
XOR(A,B)
OUTPUT
INPUT A
INPUT B
INPUT C
XOR(A,B)
If A and B are the same,
(both TRUE or both FALSE),
then the output is FALSE,
otherwise the output is
TRUE.
0-1 EDGE(A)
input A
output
input C FALSE
input C TRUE
Duration: 1 block diagram cycle
t
Rising Edge Trigger
Input B is not used.
This function outputs a pulse of 5ms duration when INPUT A to the block
becomes TRUE. When INPUT C is TRUE, the output is inverted.
The output is held TRUE for one execution of the function block diagram.
