Thank you both for your help.
I set variable as retain + I deleted default value from INIT.
Duing build I have this error: Storage area of the CPU for retain variables is too small for variable ‘Test’. Configure PV memory in CPU Configuration. 9096
I did not find anything about RemMem, PV memory, persistent variable in Cpu.sw. I use X20BR9300, X20DM9324 and X20CS1020. In tech spec I did not find info about remanent variables FRAM capacity. So problem will be maybe there?
Thanks
