CMP_W

CMP_W

cmp_w

The CMP_W component compares the magnitude of the values applied to the input pins IN1 and IN2.

The result of comparing is function of the value applied to the qualifier input QLF.

Using this function block you have the possibility to change, during run-time, the logic of comparing simply changing the value applied to the QLF pin.

The function block returns TRUE, on its OUT output pin, if the condition is verified else it returns FALSE

QLF Pin	Equation	Related function
0	IN1 == IN2	TRUE when IN1 is equal to IN2
1	IN <> IN2	TRUE when IN1 is different by IN2
2	IN1 >= IN2	TRUE when IN1 is greater or equal to IN2
3	IN1 <= IN2	TRUE when IN1 is less or equal to IN2
4	IN1 > IN2	TRUE when IN1 is greater than IN2
5	IN1 < IN2	TRUE when IN1 is less than IN2

If the value applied to the QLF pin is greater than 5 then the function block returns always FALSE.

For supply a constant value to the QLF pin you can use the CONST or the IDENT function blocks.

Net plugs

Plug	Description

IN1	The first value to be compared should be applied to this pin

IN2	The second value to be compared should be applied to this pin

QLF	A value, from 0 to 5, applied to this pin selects the appropriate logic equations for the comparing

OUT	The result of the comparing will be available on this pin
