Recover a code from controller

I lost the program that was once transferred to the controller(X20 CP 0484). Is it possible to transfer the program back to Automation Studio from the controller? I am able to run the program through the mappview.

Hello,

this would only work if the project has been stored at the plc during the project installation.
The project needs to have the option “Store project source files on target” activated.

If the option was activated and the project installed on the cpu you can open the project via the menu option File / Open project from target after establishing an online connection.

If the option was not activated, I can not think of any possibility to retrieve the project incl. the source code.

Hello,

An second option, which could lead to a partial recovery, would be an activated Source file comparison on the target. This would allow you to compare files with its content. You would be able to manualy recover it by comparing. But this has also to be manualy enabled in advance.



If you have enabled the FTP User on the PLC you can access the PLCs internal CF Storage and manually upload the binary content. This would at least allow you a manual backup copy of the current Binary code.
