PC and FANUC robot TCP/IP Communication

Quote from SkyeFire

The KAREL program can be programmed to do anything a "normal" KAREL program does.

Thank you SkyeFire,

Actually, I confused myself and do not exactly figure it out how to leverage this feature, I mean to trigger a KAREL program it is ok but I need to exchange vision data which will be utilized by App2. Sorry I am stuck and it is the first time in my life I am doing something with a robot and assigned this huge task .

n my use case, various Flags and DOs were set in response to specific arguments embedded in the URL, and status information was passed back in the response string.

Can you provide a startup example for the above-mentioned operation?

Can I send JSON data (could be POS reg data or U/T frame) from the robot to AP1 using an HTTP POST request?

Hi,

Following is the simple KARE routine that I am calling from the TP program to run a visioning process but I am getting an error of 11715 what does it mean? Code came from KAREL programming Manual

PROGRAM Test_Vis_cmd

%STACKSIZE = 4000
%ENVIRONMENT CVIS
%ALPHABETIZE
%COMMENT = 'IRVision CAL Built-IN'
%NOLOCKGROUP
%NOPAUSE=ERROR+COMMAND+TPENABLE


---------------------------------------------------------------------------------------------------------------
--DECLARACION DE VARIABLES
VAR
    STATUS : INTEGER
    visprocess : STRING[8]
    int_value : INTEGER
    real_value : REAL
    ---------------------------------------------------------------------------------------------------------------


BEGIN
    --GET_TPE_PRM(1,3,int_value,real_value,visproces,STATUS)
    --V_RUN_FIND, snap an image and run the vision process
    V_RUN_FIND('visprocess', 0, STATUS)
    -- success if status is zero
    IF STATUS <> 0 THEN
    WRITE ('V_RUN_FIND FAILED WITH ERROR CODE ', STATUS, CR)
    ABORT
    ENDIF
    -- V_GET_OFFSET, get the first offset from the run_find command
    -- put the offset into VR[1]
    -- call V_GET_OFFSET multiple times to get offsets from multiple parts
    V_GET_OFFSET(visprocess, 1, STATUS)
    -- success if status is zero
    IF STATUS <> 0 THEN
    WRITE ('V_GET_OFFSET FAILED WITH ERROR CODE ', STATUS, CR)
    ABORT
    ENDIF
    -- Get all the offset values from VR[1] so they can be put into a PR
    VREG_OFFSET(1,1,status)
    
END Test_Vis_cmd

Hi,

I have figured out the mistake and now that routine is working but what exactly does the V_RUN_FIND() routine does? i mean it just runs the specified vision processor or finds the actual object with in camera's field of view?

i run that routine for not having an object in the camera's view and I got STATUS=0 from V_RUN_FIND(), the status must be something else than 0.

Thanks a lot JM.

I am progressing in my task and able to manipulate PR with KAREL. Is there a built-in that clears the user screen on TP's user screen?

Is there any KAREL suggestion extension available for code editors like VSCODE?

Quote from jmd2777

command "V_SAVE_IMREG" which will save a snapped image to file.

Hi JM,

I used V_SNAP_VIEW before running the quoted built-in and got 1171 status. though i set image registers' count to a non-zero number in the system variables.

I'm not sure what that fault is. You can see for yourself by posting it to the controller by using POST_ERR(STATUS,'',0,0)

Edit: It is a SRIO-171 error. Dictionary element not found. Very helpful error.

Thanks, Nation

I never knew about that routine.

I checked it with POST_ERR(STATUS,'',0,0)

I used "POST_ERR" built-in to get the reason behind status code 1171. It is related camera view index, please see the attached pic.

i am using the same index for camera view in other vision built-ins like "V_RUN_FIND," which is working perfectly even if there are multiple objects.

The problem is resolved. I use camera_index= 1.

Please Consider the following built-in

V_RUN_FIND(visprocess,0,STATUS)>>> camera view=0 >>>> This is working with both camera index values 0 and1 ,Why? according to documented example (see attached picture) camera index starts from 0.

V_SNAP_VIEW(visprocess,1,4,STATUS)>>> works only with camera view=1

so, for vision commands that require camera view index Do i need to use index=1? We only have one camera in the robot cell.

Hi all (JM, Skyfire, Nation and HawkMe)

with the guidance you all provided to me I am able to

1. send positional data from socket server
2. retrieve image from image register and download it from robot's FTP server

Thanks a lot all of you.

Now I am having FROM space issue and KAREL p-code file versions.

1. FROM space: when I check the auto backup is enabled and FR directory was selected for backup, is it advisable to set UD1:/ for robot auto backup?, please note that I am also using UD:1/ for image logs I also delete one backup.dat file from FRA: dir but it does not help.
2. When uploads p-code files to real robot got an error: "program version too new"

please let me know how to resolve these issues

thanks

Quote from Nation

Most places I go to that actually do scheduled backups typically hook the robot up to a plant data network and pull backups remotely via ftp.

Thanks, Nation for your response.
Yes, I have a USB stick that remains there all the time. I go to files --> auto backup and changed the backup dir from FRA to UD1 then I go to FRA and delete a ".dat" file (contains back of robot) then I got to FR: and press F5(next) and then F4(INSTAL)->Display Backup files then I see a bunch of files so should I remove them to free FROM space?

Quote from Nation

When you compile your code in roboguide, the major version number of the virtual controller you are using must match what you are planning to deploy your code on. V8 must be compiled on a V8 controller, V9 for V9, etc.

Thanks for pointing out the compiler version. Actually, I was using a trial version of Roboguide and I installed V8 to V9 controllers as the trial license has expired so I use "krans" from cmd to compile the KAREL source file, see the attached picture. Is there a way to compile KAREL source files with V8?

Thanks Nation

Hi again Nation

I am having the following error during the compilation of all KAREL programs that included vision built-ins
