What is the real reason that coupling profinet device via KRL is Timeout ?

    Hi! I'm working on a KRC4 robot,here are some related info:

    1.KSSVersion :8.3.28

    2.Profinet KRC-Nexxt 3.2

    3.tools:gripper and servogun

    4.tool change device:ATI

    The problem is that when I dockon the gripper and coupling the profinet device(USER ID:78) via KRL command :

    RET=IOCTL("PNIO-CTRL",50,78)

    Wait for RET==0

    In most cases , it executed successful. But sometimes it's Timeout, The RET value was 1,so the robot was waiting RET ==0 until we found it's not working,but if I run this coupling KRL command again,it's always coupling successful(the RET value became 0 ). According to the manuals,the RET value means different coupling status,0 is executing successful,1 is executing Timeout,2 is internal error.why?why I need to execute the command second time?or I should optimize the dockon program:

    IF the RET==1then run KRL command again.

    It's like a useful idea. But my question is:

    1.what is the real reason for "Timeout",the profinet cable and power supply is ok.

    2.what is the difference between "the profinet device lost connection" error and profinet coupling"Timeout"?

    3.how do you bros program the profinet coupling KRL Macro:grinning_face_with_smiling_eyes:

    Thanks for your reply and share.:winking_face::winking_face::winking_face:

    I would add that in some ProfiNet devices, like Festo manifolds, there are differences between regular modules and "docking" modules (FSU), and is very common take a look at ProfiNet configuration and find that the network was misconfigured with a normal module, when in fact it should be configured with the docking one. Most of times the regular ones will work, but will take more time to finish the bus coupling. But sometimes You will have timeout problems.

    And older GSDML files also can produce this kind of error.

    well, are you sure timeout value is not set too short?

    and why is it hard to post EXACT message - with message number AND timeout value?

    did you read READ FIRST?

    My bad...this happened few weeks ago,and recently it works well.I think Timeout is easy to understand, the real reason is worth to discuss:frowning_face:. Back to the question,the Timeout value is 1000,I didn't change it. When waiting for RET==0, I just need to run KRL command again and coupling successful

    Thanks! You mean add that is "IF ret==1 THEN run KRL command again"?

    The module is SMC and I think GSD should be OK? I'll check it.

    As you say ,sometimes we still have,It's not easy to figure out the root.thanks for your share:winking_face::winking_face:
