micapp Posted February 20, 2021 Report Share Posted February 20, 2021 What is the coding on Version in Unilogic? a) When do we need to install New firmware? Can we read this from Unilogic Version? b) I delivered a program made with Unilogic 1.31.106. My customer updated the program on the PLC with 1.31.125. What happens if I now try to install again with 1.31.106? Will I get an error? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted February 21, 2021 MVP 2023 Report Share Posted February 21, 2021 It depends on the database version, which is not widely published. Can you open his .125 program in your .106 installation? Joe T. Quote Link to comment Share on other sites More sharing options...
micapp Posted February 22, 2021 Author Report Share Posted February 22, 2021 No, but I tried to update program generted by 125 on firmware generated by 106. The databaseversions is 82 and 100 but does not protest when updating on PLC Quote Link to comment Share on other sites More sharing options...
