How to unlock CP1L (The program area is protected)

Post by ksvitae »

Hello everyone,
I have an OMRON CP1L-M60DR-A PLC protected with:
AR99.00 = 1
AR99.01 = 1
AR99.02 = 1
AR99.03 = 1
AR99.04 = 1
THEREFORE : AR99 = 001F

The last bit AR99.04 is not documented in the Omron PDFs
and with this protection, the program area is read- and write-protected.
I even tried with applications that find passwords, but it doesn't work.
Please, can someone help me?

Hi!
Your controller is protected to the maximum, all protections are enabled, for reading, tasks, copying to the card, overwriting the program, A99 = F, and enhanced A99 protection is also enabled.03 = 1 Total : A99 = 001F All known programs cannot bypass enhanced protection , other methods and tools are needed here ... (boom)
I can sympathize with you.. (thnx)
