Can you re-enable power to the UR5E arm after a protective stop with an external "reset" button?

I am trying to set up an extrnal "reset" button that will enable an operator to restart the robot arm after a protected stop with out restarting the arm from the teach pendant.

You would need something like a PLC or computer to send the commands to the dashboard server on the robot but yes it is possible to do that.

So if I have a PLC how would I do that?

I know one way is to send socket commands to port 29999 on the robot. You can dismiss the popup and then send the play command. There is a whole list of commands here for CB3 (there’s a link to e-series on that page). The other would potentially be over either Ethernet IP or Profinet depending on what your PLC supports. I’m not sure though if you can dismiss the popup from those interfaces. I’d have to research that.

Thanks, I’ll try those suggestions

Hi
When the UR is gluing and for some reason a protective stop occurs the glue stays on (making a mess), is there a way to turn the Glue output off and turn it on when the reset button is pressed? the issue is that on some parts of the program the glue should be off so I only need it to turn on if its on the specific position on the program.
Thank you

You can set the output to be low when not running, that will set it off anytime the program stops.

You would then need a thread monitoring the actual desired state of the button and setting the actual state to the desired state. So in your main program instead of setting the output on or off you would set the state to True or False, something like this. Just set the thread to loop forever, that way when you restart the program the glue will turn back on if its needed to be

local turnGlueOn = True # Would cause the glue to turn on
turnGlueOn = False #Would cause the glue to turn off


thread 1():
  set_standard_digital_out(PORT, turnGlueOn)
  while(get_standard_digital_out(PORT) == turnGlueOn):
    sleep(0.1)
  end
end
