Functional Description
MODE Description
SWITCH - switches the signal source
between auxiliary and source analog or
logic tags
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = INPUT 2
INVERTER - inverts the source logic signal If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = Logic Inversion of INPUT 1
AND - gives AND-ed result of source logic
signal and an auxiliary source logic signal
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = INPUT 1 AND INPUT 2
OR - gives OR-ed result of source logic
signal and an auxiliary source logic signal
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = INPUT 1 OR INPUT 2
SIGN CHANGER - reverses the sign of the
source logic signal
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = Value sign change of INPUT 1
MODULUS - produces the modulus of the
source logic signal
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON OUTPUT = Modulus of INPUT 1
COMPARATOR - changes destination
logic signal to TRUE when source analog
signal is greater than auxiliary analog
signal
If ADVANCED = OFF OUTPUT = INPUT 1
If ADVANCED = ON If INPUT 1 ≤ INPUT 2 OUTPUT = 0
If INPUT 1 > INPUT 2 OUTPUT = 1
