How to disable AB's default password

1 post in this topic

Most of you, I'm sure, are aware of the backdoor password for some of the PLC5 processors.  It appears that some people in our plant, that don't have access to class 1, also are aware of the backdoor password and are able to bypass the security right to class 1.

Question: is there a way to disable AB's default password?


Edited by TWControls.  It's a good question, but site rules prohibit the discussion of password circumvention so let's not mention the actual default password.
