Hello,
If you got the KUKA software to work, most of the work is done.
The problem is most likely related to the mxA version - KUKA|prc should present you with an error number if it doesn't work, which you can look up in the manual.
If you let me know the exact version number of your mxA, I can send you a specific build that uses your version of the library.
The physical IP only applies when you are running mxA on a virtual robot controller. Unless you are using multiple robots, leave the ID at 1.
Best,
Johannes
