Hi Team,

    we are using UR3e Robot and the version is 5.4.2, we send the command to robot via socket programming and the size is 500kb. we get the protective stop error "C271A3: Low level real-time thread: Runtime and communication out of sync", we don't have idea to resolve it. please give suggestion to solve it.

Thanks

What is the command you are sending?  Are you trying to send this as a command while the program is running?

No, I am not sending command, while the program is running, when I send the code below 500kb its work fine. when the program is above 500 kb, I get the error of protective stop. 

ex:
def function:
-------------
------------
end 

the above format, we using for send command to robot 

It may be good to ask this question to UR support team. They may be able to help with this.

Once you have the solution, come back and share it with us!
