7.3.8.4 OR
Brief description
BOOL-type OR function block with four inputs
Mode of operation
This function block links the binary variables at inputs I to a logic OR (disjunction) and
outputs the result to its digital output Q.
Q = I
0
v I
1
v I
2
v I
3
Output Q = 0 when the value 0 is present at every input from I
0
to I
3
. In all other cases,
output Q = 1.
7.3.8.5 XOR (exclusive OR)
Brief description
BOOL-type XOR function block with four inputs
Mode of operation
This function block links the binary variables at the inputs I according to the exclusive OR
logic function and outputs the result to its digital output Q.
Output Q = 0 when the value 0 is present at every input from I0 to I3 or when the value 1 is
present at an even number of inputs from I0 to I3.
Output Q = 1 when the value 1 is present at an odd number of inputs from I0 to I3.
7.3.8.6 NOT (inverter)
Brief description
BOOL-type inverter
Mode of operation
This function block inverts the binary variables at input I and outputs the result to output Q.
Output Q = 1 when the value 0 is present at input I.
Output Q = 0 when the value 1 is present at input I.
