Greetings URCommunity,  
I am trying to create a small app in which I get feedback from digital inputs and outputs. I have not been able to connect my computer to the RTDE port (30004) and get a feedback of them. Has anyone ever managed to do it using C# language?  
Any help is much appreciated,  
Best regards

@PMonforte I myself have just started using RTDE. I was able to connect to a UR5 CB3 using the record.py example script and got I/O information using the actual\_digital\_output\_bits recipe. I use the Spyder IDE. It has a great console that describes all the different problems encountered with the script. I know it is not C# but it might give you an idea what to be looking for as you transition to C#.

Hi, since you are in C#, you can take a look at this implementation of RTDE : [Universal Robots SDK documentation](https://underautomation.com/universal-robots/documentation/rtde)
