ARRAY with and ENUM

2022-06-16T07:17:58.867000Z

Hi Fless, hi i-campbell,
I added the warning disable as Fless suggest, but if I use the enum in the project the warning come:

[WARNING] INDEX C0125: The constant 2 is assigned to more than one enumeration
Compile complete -- 0 errors, 1 warnings

I think that the only workaround (without using global constant) is to remove the 'strict' attribute.

It seems that CODESYS does not support this way to use array and enums. I was only curious to understand if there were some other way conform with standard programming rules.

Thanks!
Francesco

Welcome Francesco,

this works for me:

{attribute 'qualified_only'}
{attribute 'strict'}
TYPE INDEX :
(
    ID1,    //0
    ID2,    //1
    ID3,    //2
    {warning disable C0125}
    LASTELEM := ID3
    {warning restore C0125}
);
END_TYPE

PROGRAM POU
VAR
    values : ARRAY [0..INDEX.LASTELEM] OF INT;
END_VAR

values[INDEX.ID1] := 1;
values[INDEX.ID2] := 10;
values[INDEX.ID3] := 100;

did you remove the 'strict' attribute from your enum definition already?
