Hello,
I have an S 430iw robot that is removing the group number on its own about every 6 months or so. I have a few "calls" for different programs if there are different parts present via I/O. This robot will spot weld so much of the program then lose its group number (under program details the group number will be all ********* instead of 1******** Which makes the robot fault under PRIO defined group not specified. I have to delete the program that lost its group number and reload my backup from my flash card to get running again. Its not that big of a deal until I get called out at midnight to do it. Anybody seen this before?
