Hello,

I am setting up the profane communication for my UR robot against an s7 1200. Since then I have tried to also add to my welding machine in the communication. So after a lot of experimenting, this has appeared when I look at the UR robot’s int register. I do not know what it is or why it is so since then the values change all the time. even when a program is not running.

 ![20201009_124716](https://us1.discourse-cdn.com/flex020/uploads/universal_robots/original/2X/1/13c52dd819b4d7fdda80d07e53034cc1a308d80e.jpeg)

I have tried and run a program to see if I get any changes in the registry but nothing changes.

it should look like that with the values?

Best regard Martin

Hi Martin,

I have not experience with the Profinet interface. Have you read the article:

[https://www.universal-robots.com/articles/ur/interface-communication/profinet-how-to-guide-e-series/](https://www.universal-robots.com/articles/ur/interface-communication/profinet-how-to-guide-e-series/)  
And the attached documents?

What do you want to read/control via the profinet interface?

Best Ebbe

Did you ever figure out why this was happening? I am having similar issues with Ethernet/IP to my Allen Bradley PLC.

Hi,

Not sure what bit/byte address within the fieldbus register table %ID168, etc is mapped to but I suppose it might be some joint data. You will typically see all sorts of data from the robot chaning even if it’s not running a program (example - joint motor current or temperature).

Have you looked at the UR ProfiNet guide :  
[https://www.universal-robots.com/articles/ur/interface-communication/profinet-guide/](https://www.universal-robots.com/articles/ur/interface-communication/profinet-guide/)  
and the document at the bottom titled pn-iomessage.pdf … this might help.
