We are currently using a UR20 robot. Could you please tell us how to configure EtherNet/IP to allow the PLC to read the robot’s error status? Also, does the robot’s scripting language have a function similar to “JUMP” for program branching?
Have you found the EtherNet/IP tutorial? Ethernet IP guide - 18712 - collaborative robots support
Here you can see which signals are sent between PLC and robot in both directions: eip-iomessage.pdf
Regarding the Jump; there sort of is a function (thanks to Eric Feldmann): How to jump to a certain line in the program via Script or Assignment - Technical Questions - Universal Robots Forum
There’s a flaw with it which you can read in the thread. It jumps to a line number, so if you insert code before the line number, you won’t achieve the correct jump anymore without also editing the jump command.
Here’s your English translation 
I’ve checked the EIP documentation.
Will this type of alarm appear in the “Is fault” register, or is there another way I can read its error status?
Also, I’d like to ask whether the warnings and errors shown in POPUP messages can also be detected as fault statuses.
