 Posted: 11/04/2019 01:30 Post subject: Swapping EEPROM from PLC?? |
 |
|
Hello,
Unfortunately I have a S7-200 SMART (SR40 CPU) v2.01 on a machine from China that has a dead output. I cannot read nor write to the PLC because of Level 4 protection.
Is it possible to swap the EEPROM to another working PLC (without burned output) of the same tip to keep the program and parameters?
The program is level 4 protected and the manufacturer of the machine out of business.
I hope EEPROM swap could work or is there a way to downgrade to level 3 on the SMART S7-200 v2.01? I could modify the program to use another output which is fine (unused)
Any clues will greatly help!
Thank you very much!!!

The standard S7-200 SMART CPU models support standard, commercial microSDHC cards with a capacity ranging from 4 GB to 16 GB using the FAT32 file system format. You can use a microSDHC card as a program transfer card for portable storage for your program and project data.

Thank you for the manual but I cannot transfer any program neither UPLOAD or DOWNLOAD (To SD card or to the computer )since the level 4 prohibit this. They ask a password if I want to STOP the PLC from STEP7 SMART MICRO/WIN software.

I took a picture to show you what I am talking about for Level 4 System Block Security.
The manufacturer of the machine locked any operation on the PLC with this security... how to bypass or possible to swap to another PLC ?
Thanks a lot!

I see you modified the bin hex at offset starting at 448 ---> 05 9A 45 78
What it does?
Thanks for the software but it is for 200 CN series.
I have S7-200 SMART SR40 CPU with ethernet programming. There is no serial PPI or USB possible.
More like this --->>> http://www.plcjiemi.com/smart.htm (translate to your language) but it's very expensive.
Our machine PLC configuration:
Thanks luke for all the time you took to reply!
