Hello to all, since we switched from RS 5.60 to 6.00 we are not able to create virtual signals in RobotStudio, why is this. Thanks.

hello,  
in rw6 you dont have to assign virtual signals to a virtual board, just leave it blank.

Thanks Peter, I’m trying to use backup from S4C+ in RW 6, actually EIO.cfg

Not so easy any more - the format of the EIO file has also changed with RW6.
