Dear reader,

I created a new “Station with Robot Controller” and after some testing with RAPID I want to dive into socket programming. For this I need to add the `PC Interface` option to the system. I’m searching for a option somewhere which allows me to add options like the `PC Interface` though maybe I need to create a completely new one?

Thanks

I believe that you should be able to modify your system, in system creator?

So instead of creating a new system, you just edit your system. You might have to do an I-Start though

Hi Svoldgaard,

Thanks I found it. For anyone facing the same problem, you need to open the “Controller” tab, then click on the “System Builder” icon. In the popup that opens you browse to the directory of you current system and press “Select folder”. Then the “Modify” button becomes enabled.

You also need to I-start the controller to activate the change. Please do not forget to backup your controller prior to the I-start as all your changes will be lost as a consequence of the I-start. When the I-start has completed you can restore the backup.
