Hello, I've an issue that I'm trying to solve out, and don't know where I'm wrong.
On codesys 2.3 , I'm trying to use ENUMRATIONS.

TYPE DisplayVisuPage :
(STRUCT
END_STRUCT)
(
PAGE1 := 0,
PAGE2 := 1,
PAGE3 := 2,
PAGE4 := 3,
PAGE5 := 4,
PAGE6 := 5,
PAGE7 := 6,
PAGE8 := 7,
PAGE9 := 8
);
END_TYPE

Then my issue is in a FB
as variable I have
DisplayPage: DisplayVisuPage;
Vara: BOOL;

My problem is that I've a fault message saying " No number or needs constants"

when I write similar as below:

IF DisplayPage. PAGE3 THEN
Vara:=True;
END_IF

I know that if I write , it's gone a be OK , but it's not what I want to do

IF DisplayPage =2 then
Vara:=True;
END_IF

I believe I have an issue on how Ihave right my ENUM but don't know why. What I've seen is that I can't change the datatype of my ENUM exept to get fault message.

Thanks for the help.

Hi
The ENUM definition is wrong.

Try this:

TYPE DisplayVisuPage :
(
PAGE1 := 0,
PAGE2 := 1,
PAGE3 := 2,
PAGE4 := 3,
PAGE5 := 4,
PAGE6 := 5,
PAGE7 := 6,
PAGE8 := 7,
PAGE9 := 8
);
END_TYPE
