Description
The block supplies the value Y (output Out ) belonging to a value X (input In ). The curve is
specified by the points P1(x
1
,y
1
) and P2(x
2
,y
2
) (see inputs).
When the input value is outside x
1
..x
2
, a limit value violation is also indicated. The
exceeded y value is written to Out and either P1 limit or P2 limit is set to 1:active.
NOTE
The 32-bit range of the inputs cannot be fully utilized since this would cause overflows. All
x or y values may only be located a maximum of 2
30
away from each other. For correct
function, x
1
must be less than x
2
.
Inputs
No. Name Datatype Scaling Description
1
In
I32 – x-value whose y-value is to be output on Out
2 P1 x I32 – Value x
1
(must be less than x
2
)
3 P1 y I32 – Value y
1
4
P2 x
I32 – Value x
2
5 P2 y I32 – Value y
2
Outputs
No. Name Datatype Scaling Description
6 Out I32 –
Linear y value interpolated between P1 and P2 (belonging to In ).
When the value is outside the area marked by P1 and P2, y
1
or y
2
is
output.
7 P1 limit B –
Status limit P
1
:
0 = the x value on In is equal to or greater than x
1;
1 = the x value on In is less than x
1
( Out = y
1
).
8 P2 limit B –
Status limit P
2
:
0 = the x value on In is less than or equal to x
2
;
1 = the x value on In is greater than x
2
( Out = y
2
).
