Need help decrypting password from S7-200CN EEPROM dump (24C256)

Subject: Need help decrypting password from S7-200CN EEPROM dump (24C256)
"Greetings! I need assistance with decrypting a password for an S7-200CN controller. I have read the EEPROM dump from the 24C256 chip.
I checked the offset 0x5E2, which is typically where the password is stored in many S7-200 models, but in this specific dump, it appears to be empty (or the data doesn't match the expected format). It is possible that the password is stored at a different offset or is encrypted/hashed in this CN version.
Could someone please take a look at the dump and help me locate or recover the password? Any guidance on where the CN series stores security data would be greatly appreciated."
