Then select all those tags and synchronize them with the PLC tags (button on the right of the export and import buttons). Regards, Frink

Where as how to do for PLC tags associated with Area pointers ? Hello Syamkrishna Deleting the IM Folder does reset all temporary HMI files that are generated by compiling in TIA Portal. It does not specifically reset a single type of issue, it could help if you have any inconsistency in the temporary HMI files. If this do not work, then the error seems to be a different one. Perhaps something in your configuration is not 100% right. If you give us more details or if you open an own topic with your Issue, perhaps we can help you Bye Murof
