Everyone knows about the plc5 and slc password bypass is
"ABUNLOCK"
its been out there for years. Like its a deep secret
The contrologix is a different story. They actually have this under tighter wraps.
Even the siemens processors can be bypassed.
Its amazing the amount of hackers that want to bypss someone's intellectual property.
I know that AB has a standard policy if you can get a few signatures from your company stating for certain reasons they will send the file back unlocked.
