During dupcs for one pc, it is not responded and ONB disconnected! How we dump this PC?
I tried to dump from different point (ex. dupcs pc20.10>pc20.99) but with same response, stop dumping at first PV elements!
The PC is running with internal applications, logic, objects without problem. But we need to dump as we shall initialize and reload the controller because of change in DB for adding new IO cards! All other DB & PCs are dumped without any problems.

I had similar problem in the past, it was impossible to make online connections within one PC program, Online Builder always crashed with "FATAL ERROR" message. The only way was to delete the whole PC program and reload it from the source file. But the DUPCS command worked, so it was different from your case.
Create a new node in Application builder with the same PLC type and same network address. Then open Online builder in the new node and try to dupcs PC20 again.
Why you need to load controler from source codes ? Are you upgrading CPU card ?
For IO redimensioning it is enough to use binary backups DUTDB, DUTPT (DUMP as well) , clear CPU and redimension during LOTDB command. Last step is LOTPT and DICONFIG, remember all MCC breakers must be off on DICONFIG.
If you really need to load from source codes, don't forget to do dudbs SRCE:xxxx,SEL=ALL/OUTPUT that dumps also values. Also do DUMP, DUTPT, DUTDB before clearing CPU.
