Firmware version check when installing new program with memory stick

[micapp]

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?

It depends on the database version, which is not widely published.  Can you open his .125 program in your .106 installation?

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
