Hello,
I have a communication problem on my UR3. I plug in the ethernet cable and it doesn’t show any network activity. Changed two cables, same problem. Changed the connectivity, first with the cable connected to the router and then connected directly with my laptop, same problem. Looked on the settings and ethernet is enabled.
I can’t figure out how to get connectivity over ethernet. Can anybody help?
Thanks
Have u fixed it yet. I’m in same problem 
Hi, i have had this problem , i am using an UR16 which is connected to a Siemens PLC.
When i tryed to change the robot´s IP , the console didn´t show any problem , but i wasn´t able to make ping with the robot , after some tryes i simply rebooted the robot and as soon as it was powered on , the PLC connected with it.
Then i also did the same with an UR10 and again , until i didn´t reboot it , the address didn´t get connected.
you need to change the IP and subnet mask in your PC too. you can search it on Youtube.
