Hello all, I want to make a connection between LabVIEW and a S120 CU310-2 PN so I followed this guide : https://support.industry.siemens.com/cs/ww/en/view/99684399 Right now when I go into the VI "start.vi" I get the error 402 which means that the xml file cannot be opened. I made sure that xml file that I get from TIA portal is in the right directory "user.lib\PNIO". Are there any ideas that could help me out here? Thanks in advance Nouâman
