Everything seems fine in Linx. I can delete add auto config, just no path in rs logix. First time it happened was a new 1400 plc that had no ip address so i wanted to use df1. Auto config in linx, opened the .rss file and did not have a path. Went to controller properties, Controller Communications tab, then i had a path to df1, clicked on who active, saved the program, then path was open under systems comm. Next upgrade i could not restore it with these steps? Never had to do this before and not sure why it is happening. Just tried these steps and it worked at this time. Really confused.
