    Hello,
    I would like to convert a DINT format in Word but with a different way to TO_WORD.
    For example, if I use TO_WORD with 70 000 ( 1 1170 hexa) I will have only a word with the value 1170 (hexa). I would like to convert the value 70 000 (decimal) with a LSB word and MSB word.

    How can do that ?

    Thanks for your help.
    Pascal.

    Hello
    With a UNION:

    TYPE uDINT_WORD :
UNION
    AsDINT: DINT;
    AsWORDs: ARRAY[0..1] OF WORD;
END_UNION
END_TYPE

    then create a variable of this type and the WORDs

    MyDINT: uDINT_WORD;
LSW: WORD;
MSW: WORD;

    Then you can access the WORDs...

    MyDINT.AsDINT := 70000;
LSW := MyDINT.AsWORDs[0];
MSW := MyDINT.AsWORDs[1];
