Hi, I test a metod for find password from CQM1H-CPU21(51-61) and share with all.
it's very easy: you must install (Plc Backup Tools V6.0) then select UM option and upload from PLC, after this,
you open UM file with any HEX Editor program.
Now you can see password in 0590h memory address.
this metod tested for C200-CPM1- CQM1-CQM1H.

Hi Aliam,
If You Try To Release The Password More Then 5 Times With The Worng Password from CQM1H-CPU51/61.
You Won't Be Able To Release The Password Any More
Even If You Know The Right Password
Jamie Quach

Please upload Plc Backup Tools V6.0 !
