Can I use internal Features, read or write them?

I don't understand at all how to use custom surfaces. I have a suspicion that this is a problem with UR itself and its protocol.

Hello Folks,

We have found a very strange bug in your library. We are using a .Net 3.5 C# Classlibrary, which is called by some other applications. The Robot is connected to our Network via Ethernet and the library communicates via RTDE.

Somehow the robot disconnected every couple minutes from our network, which is strange, since its connected wired by ethernet.

We found tons of logs in the UR System which are looking like that:

Is it possible to send multiline scripts?

This particular example will execute the last command, I have tried different configurations and different delimiters

In order to do a fresh install of Python you need to change the setup.py:

from:
data_files=[('underautomation/universal_robots/lib', ['underautomation/lib/UnderAutomation.UniversalRobots.dll'])],

to:
data_files=[('underautomation/universal_robots/lib', ['underautomation/universal_robots/lib/UnderAutomation.UniversalRobots.dll'])],
