You have to read memory using ponyprog, and then, buy a new PLC, same model and version, and write the memory. Put all in back and create your back-up from new PLC.

well we ended up sending the old plc to siemens, it was an old style s7-200 and the newer power supply cards dont match. they have old power supply cards and put our plc card onto it and extracted the program. then emailed it to me..... siemens was very helpful once you talked to a tech....
