Hello there, I am new to robot studio and just begun a few weeks ago. It al went smoothly but i am facing errors at the moment i have never had before. 40165 Reference error ![](http://forums.robotstudio.com/webwiz/7764/errors.jpg) Since yesterday i get these errors, first i changed the name a 100 times, but that was not causing the error. Also since yesterday i have updated robotstudio 5.14 to 5.15 The robot is operating on RS4 Is 5.15 not supporting RS4 anymore? I have errased all my newer added targets i had made with 5.15 and dit it again with 5.14 and voila, the errors are gone?!?! Please help if this is true or there might be bigger problems? Many thanks! ---

update: It seems to be the problem that paths made in RS 5.15 can’t communicate with the RS4 robot system I have made a new path in RS 5.14.03 and moved the instructions out of the old path an into the new path made with rs 5.14.03, the error is gone now. I have made an vertification of the problem to regenerated it ones again The error has returned. Anyone familiar with this problem? Many thanks! ---

Please upload the program generated by RS 5.15 that cause the reference error on S4 so that we can have a look. ---

This is a customer of ours. I called him and found out that the declarations are stored in a different module as the instructions at syncronising to VC. dont know why yet though ---

You can configure to which modules the targets and paths shall be synchronized to in the “Synchronization to VC” dialog. ---

I just find out that the path in the Syncronice to VC option were sent to the right module, but when i expanded it, it showed me that the targets were send to another module. So i loaded a module in the robot that dit not contain any targets… Right after the update to 5.15 it went wrong, i guess it re-setted the module i had chosen in the earlier version. Thanx for your post! It helped me a lot
