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...
Ofir Posted June 5, 2019 Report Share Posted June 5, 2019 Hi, As I understand you are going to add more tags/structs to the project. In this case the existing retained tags should not lose their values. Anyway I suggest to backup your project and the retained tags using UniLogic or UniApps. If you are upgrading firmware then I highly recommend to backup the retained tags. Quote Link to comment Share on other sites More sharing options...
