Send error domain, number and title to PLC

dragolollo

Hi all,
I'm doing an application in which I have to detect errors and then send error domain, number and title to PLC trough Profinet. I'm not too expert in RAPID/RobotStudio, so I have 3 questions.
1) Is what I've written until now correct and the correct way for detecting errors? I wrote the following code in a semi-static parallel task:

   VAR intnum err_interrupt;

    VAR errdomain err_domain;

    VAR num err_number;

    VAR errtype err_type;

    VAR trapdata err_data;

    VAR string titlestr; 

PROC main()  

    

    IF first THEN          

        IDelete err_interrupt;

        CONNECT err_interrupt WITH trap_err;

        IError COMMON_ERR, TYPE_ALL, err_interrupt;

        first := FALSE;

    ENDIF

 ........
   " 2) the main is doing also other things like reading the robot position continuosly, would be better to have a task only for errors management?"
.........

ENDPROC

TRAP trap_err

     GetTrapData err_data;

     ReadErrData err_data, err_domain, err_number, err_type  \Title:=titlestr;

     SetGO GO_ErrDomain, err_domain;

     SetGO GO_ErrNumber, err_number;

ENDTRAP

3) At the moment I'm sending to PLC only the error domain and number, how can I send a string?

Thank you a lot in advance!
