Do you try to go OnLine with the PLC or try to upload the project?
Unfortunately the upload of the program from the PLC to Automation Builder is not possible (for reading and editing in AB) - many other posts for that in AKS.
In case you want to go OnLine with the actual project, it has to be the last version, loaded to the PLC. Otherwise the AB will ask to download your version to the PLC, after that you will go OnLine
if you not have the source of the running program, you can not save one editable copy of plc logic.
