s7-200 CPU224 Level4 Password Backup Problem

Post by kilicustasi » Wed Feb 26, 2020 7:19 am

Hi, everyone.
We have a plc. It has a hardware problem. So we want to backup plc to restore to new plc. but it gives "The Plc has been protected to prevent program upload." error. i looked so many pages, but i couldn't find a solution. there are some software to unlock password but some of them hasn't a working link, some of them doesn't work.
If there is a solution about eeprom, i think i can do that.
This is board picture.


Is anyone can help me?
