Reset to factory settings protected CPU 315-2DP

rpcmoirans Posts: 2 Rating: (0)	Hello, I have dismounted an old machine which was equiped with a CPU 315-2DP (6ES7 315-2AF02-0AB0). The program is protected by a PIN, how can I reset the CPU without the PIN ? Because i'd like to reuse this CPU for another machine with a new program. Thanks in advance.
