    1) Install Library UTIL
    2) Use Function(Word_As_String)
    iWord : WORD;
    oString : STRING;
    oString := WORD_AS_STRING(iWord,FALSE);

    See attachment for additional information.
    Hope this is helpful.

      Thanks a lot, i have a question, I am given a word (example: hello) like Word, how do I convert it to a String? Because if I insert in the converter only one letter at a time in ASCII it converts it, otherwise not

    Here's a snippet i've used for RS232 ASCII comm on one of my application.
    I'm hoping you can extract something useful from it for your requirements.

    It converts the input string "hello" to integer. Play around with it.

    I hope i understand your question.
    Also look into:
    WORD_TO_STRING();
    TO_STRING();

    -krstech.i

    code

PROGRAM RS232_ReadRegisters
VAR

    hexDataString   :   ARRAY[0..15] OF STRING[4];
    readRegister    :   ARRAY[0..15] OF WORD;

    i, x            : INT;
    counter : INT   := 8;

END_VAR


(* Extract Hex data from Read Response dataString, then convert the hexstring to integer *)

FOR i := 0 TO gvl.PFC200.RS232.numReadReg - 1 BY 1 DO

    hexDataString[i] := MID(gvl.PFC200.RS232.dataString,4,counter);         // Extract Hex Data: MID(string,len,pos)
    readRegister[i]  := STRING_TO_WORD(CONCAT('16#',hexDataString[i]));     // Convert Hexstring Data to integer
    counter := counter + 4;

//  gvl.OMRON.to_PFC[i] := readRegister[i];                                 // Point readRegisters for I/O Mapping 

    IF i >= gvl.PFC200.RS232.numReadReg - 1 THEN i:=0; counter:=8; EXIT; END_IF;
END_FOR


FOR x := gvl.PFC200.RS232.numReadReg TO 15 BY 1 DO
    hexDataString[x] := ''; 
END_FOR
