ORSO2001 Posted May 8, 2019 Report Share Posted May 8, 2019 dears All, I will have to modify an old project where I used a lot of retained tags (was my first project and I was not very skilled...for sure worst than now 😁 )...I want to replace the retained tags with a struct referred at a DTI...then save this on the SD. my question is...if I will upload a new project , the same but with more UDFB-tags etc, the retained tags that are used at the moment still contain the same value or will be reset? just to know if I can do this without problem, because I will also update the PLC version, or if I have to think something to save the retained tags and upload these later. thanks Quote Link to comment Share on other sites More sharing options...
