Program in IRC5 roll back

Options
I did a modification of program in IRC5 controller. I transferred new module and load new parameters remotely I restarted controller. But few days later the switched off the controller. And seems that after that my modification disappeared. Did I forget something ? I dont know. I am relatively new in ABB programming.

    Hello Joel, program cannot just disappear, are you sure that program you loaded remotely really ended up in controller. If you are sure, maybe someone loaded some other program in the meantime, or loaded let's say old backup without your modifications.

    If the controller crashed or there is an error on UPS system the image is not saved correct, when the controller is restarted the old program will comeback.
