Profinet IO Device not found

Hello,

I am trying to create a Profinet communication with a simatic s7-1200. But UR does not find the plc
and from the TIA portal it only says that UR cannot be reached. UR has a profile name and IP address.
I have tried to follow the universal robots profinet guide as best I can but it still does not work for me.

Am I missing something here?

Best regards Martin

Here’s a video I did of setting up a S71200 to a UR. It’s a bit tricky but once you figure it out works very well.

One thing to remember that I didn’t know, you need to be hooked directly to the PLC via hardwire to discover the robot. It does not always work via WiFi and definitely does not work over VPN. It has to do with how Profinet uses Mac addresses to identify the devices on the network.
