I'm doing with robots from beginning of this year, so I have a maybe simple question. How to communicate UR with PC? I have plugged PC into UR via ethernet cable, but UR doesn't recognize PC and the small indicate point lights in yellow color, which says that no hardware was plugged. But in PC when I try tu ping IP adress of UR (which I have set in Robot configuration), the PC knows about UR. I'm trying new things with UR.I need this for sending variables or whole scripts from PC to UR. Or, for example, when a program in UR is doing, I send online some variable from PC and robot does something. But how to communicate through ethernet?
