Dear friend,
thanks for your response. Can you explain me how you read it ?
I want to share with us your knowledge.
What program have you use?
What adapter ?
The procedure is similar with reading the eeprom for S7-200?
Please give me more details.
All the best,
dekor

yes it is the same for a s7-200, maybe i will post a picture.
The diference is that the password is plain text, not crypted nad the memory is smaller.
