Send string via Profinet to a PLC

    Goodmorning,

    Actually i'm working on a project with a CRB15000, i'm programming it with Robotstudio. The Robot is mounting a camera that is going to read some serial numbers.

    From the camera i receive a string similar to "SN1234|123" but it could be different.

    I need to cast this string into an array of byte, so i can send it to my PLC via Profinet with SetGO.

    For example:

    PERS string sendString;

    sendString:= "SN1234|123";

    SetGO SendByte0, StrgToByte(sendString{1});

    SetGO SendByte1, StrgToByte(sendString{2});

    Ecc...

    But it didn't work

    I also tried with SetGO SendByte0, StrToByte(StrPart(sendString, 1, 1)) but it didn't work.

    What is the correct way to do it?

    Thanks everyone.

    I think syntax for sending the string should be:

    Code
    sendString{10}:= :=["S","N","1","2","3","4","|","1","2","3"];

    Additionally, the \Char argument can be used to convert it to ASCII. To implement this,

    Code
    SetGO SendByte0,StrToByte(sendString{1}\Char);

    should be used. It should be noted that the string must be sent in ASCII and then converted back to a string from the PLC

    OR

    Code
    sendString:= "SN1234|123";

SetGO SendByte0, StrgToByte(StrPart(sendString,1,1)\Char);

SetGO SendByte1, StrgToByte(StrPart(sendString,2,1)\Char);
