    see its so simple

    no need to use any conversion

    codesys is best for this

    you just define dint variable at some physical address

    define string array on the same address thats it

    e.x Dintarray: array[0..30] of DINT AT %MDW100;
    Dintarray_STRING: array[0..30] of STRING AT %MDW100;

    Instead you can use a more modern approach via a UNION for this kind of operations as it is meant for this.
    I'd suggest something like the following example;

    TYPE myUnion:
UNION
    ardiMyArr : ARRAY [0..4] OF DINT; // 16 byte
    sMyString : STRING[16]; // 16 byte
END_UNION
END_TYPE

    See CODESYS help on UNION datatypes;

      Hello!

      The size of ardiMyArr is not 5x4 = 20 bytes?

      Thanks in advance!

    Inside a FOR loop...
    StringArray[i] := DINT_TO_STRING(DintArray[i]);

    If you want to convert the numeric value of each DINT array element then use ph0010421's method. If the DINT array contains ascii data then use Aliazzz's method.
