hello,
if you want to use pc interface it is your ROBOT that needs the option PC interface
make a backup of your robot and look in the directory BACKINFO for the file backinfo.txt (this is for IRC5 robot)
there you can see all the options installed in your robot, i.e. 616-1 PC Interface
Or go on your main screen ABB to “system info” and look for “System properties/Control module/options”
BR
