Meeg Posted April 22 Report Share Posted April 22 Hi I have several "old" systems running on software 1.25.56 and now I want to upgrade these systems to 1.35.277. Can this cause any problems? The hardware is from 2017-2019? The reason I want to do this is to avoid having to many versions and also it seems that the new software have the very useful possibility to save retained tags to the SD-card. Except from this the PLC program are more or less the same. Quote Link to comment Share on other sites More sharing options...
