Writing to external file

    Hello everyone,
    I'm trying to count, how much time the welding process was avtive, so I wrote next program,that I'm planning to call in sps:


    bool mem ; bit memory 1
    IF ($IN[2371] AND (NOT mem) ) THEN ; if we caught the front of signal 2371
    $Timer_STOP[5] = FALSE ; started the timer for 5 seconds
    ENDIF


    IF ($TIMER[5] >= 5000) THEN ; if 5 seconds already gone
    $TIMER_STOP[1] = FALSE ;started welding timer
    $TIMER_STOP[5] = TRUE ;stopped timer of 5 seconds
    $TIMER[5] = 0 ;set timer of 5 seconds to 0
    ENDIF


    IF ((NOT $IN[2371]) AND mem) THEN
    $TIMER_STOP[1] = TRUE
    CWRITE($FCT_CALL, STAT, MODE, "krl_fopen", "timers.txt", "a", HANDLE) ;open file
    CWRITE($FCT_CALL, STAT, MODE, "krl_fprintf", HANDLE, "%f, %f, %f, %f, %f, %f, %f, %f, ",$TIMER[1]) ;write to file
    CWRITE($FCT_CALL, STAT, MODE, "krl_fclose", HANDLE) ; close file

    $TIMER[1] = 0
    ENDIF

    mem = $IN[2371] ;remembered the last state of 2371


    So what the program exactly do: in bg logic it scans for active signal 2371, since its going active - its waiting for 5 seconds (5 second timer), then, start the other timer and counts how much time 2371 was active writing that numbers to timers.txt file


    My question - I'm getting the "variable not defined" error in all cwrite lines. Also, Im getting error "The type of sentence is not equal to STAT_T" and "The type of sentence is not equal to MODUS_T". I checked manual many times and my code for writing into file exactly the same, also, i checked another thread: https://www.robot-forum.com/ro…d-hour/msg55503/#msg55503
    And as you see, my code seems to be ok. Whats wrong?

    your code is not ok...


    1. you need to declare AND initialize all variables, including STAT, MODE, HANDLE
    2. your second CWRITE is trying to write 8 values (you have eight placeholders %F) but you are only passing one value ($TIMER[1])



    at begin of your program add something like

    Code
    ; this is declaratation section
DECL STAT_T STAT ; declare STAT variable
DECL MODUS_T MODE ; declare MODE variable
DECL INT HANDLE; declare HANDLE variable


    then you need to do initialization section

    Code
    HANDLE = 0 ; set initial value for HANDLE
;etc.


    and finally you can do rest of programs like you wrote...

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

    btw, only use recent version of CWRITE manual for KRC4, check manuals download section, do not use one in topic linked in your post.

    There is no assignment to a variable called $ACC_VEL inside bas.src. Do you mean $ACC_AXIS? $ACC_AXIS is used to program axis acceleration for motion commands. Since no motion commands are allowed inside a sub-program These assignments are prohibited. Probably you are calling the INI-Fold in your submit. So just delete it.

    Yep,already fixed that, but now there is ANOTHER problem (oh God!). Somehow there is nothing that is writing into file. I checked C:\KRC\ROBOTER\UserFiles and there is timers.txt file (that is good, it was created by itself,that means the line with opeping worked), but there is nothing into that txt file. Only 1.
    I started to think,that my code is not working and made a test - instead of writing result into txt file i wrote it into INT variable. And it worked! that mean that countings are ok,the problem is in the writing to the file. Any ideas?


    UPD:
    I wrote separate program just to test writing to file,and as it shows when im trying to write a string to a file-all works fine. But as soon as I chose variable- nothing works. I think I'm sending wrong params,thats the problem. My variable is $timer[1], its int.

    In CWRITE($FCT_CALL,STAT,MODE,"krl_fputs",HANDLE,"%f,",$TIMER[1]):


    %f is usually the type qualifer for floating point values. $TIMER is of integer type so maybe should try %d and use krl_fprintf(). fputs is for strings.

    Thanks a lot,it worked! THe only last problem-how to write variables in list? Right now its just adding the nubmers to the previous, and it looks like " 4523412467123876128476"
    but what I need is
    1234
    5678
    9101112


    etc.


    I can just can add another cwrite, with spacebar but hot to write /n?

    Hello Acapulka,


    Have you already achieve the LF or CF spacer ? or just use separator to identify them out like 12,34,56....?
