How to read the popup-text in UR system through a tcp connection

Technical Questions Robot Communication

There seems no solution in client interface.
The only way I can find is to use remote desktop.

Have you solve the problem? I am very curious about how to detect the message. : )

What is the purpose for reading the text, is it for a fault or other SAFETY RELATED popup or an error code? Or is it for popup that’s created in the program?

Hi Mike,

I am running into the same issue. I need to access the popup error message through python using ROS, but it seems like there are no existing solution for that. Could you advise me on how to approach that problem please? Thanks!

Actually there is no way direct to read the popup text but you can read out why the popup comes up by reading the Safetystatus with Dashboard server.

ds = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # configure Connection
ds.settimeout(1) # set timeout
robot_ip = '192.168.1.2' # replace with your robot IP
port = 29999 # Dashboard server Port
ds.connect((self.robot_ip, self.port)) # Connect robot

ds.send(ds.sendall('safetystatus\n'.encode()) # Ask for the safetystatus
print(ds.recv(4096).decode()) # print the response

Possible responses will be:
“Safetystatus: ”, where status is
• NORMAL
• REDUCED
• PROTECTIVE_STOP
• RECOVERY
• SAFEGUARD_STOP
• SYSTEM_ EMERGENCY_STOP
• ROBOT_ EMERGENCY_STOP
• VIOLATION
• FAULT
• AUTOMATIC_MODE_ SAFEGUARD_STOP
• SYSTEM_THREE_ POSITION_ ENABLING_STOP

Through Dashboard server you can also unlock protective stops and close the popup.
If you really need to read the popup text, then i would recommend to do this with ssh connection and read the log which contains same messages as the popups.
