Claim 8:
9. A method for an intelligent electronic device (IED), the method comprising:
evaluating local inputs and those received from an external source;
determining an output of logic equations based on the input from one or more of the external source, the local source, or locally calculated logic equations;
setting one or more access control variables based on the output of the logic equations;
receiving an access control command that requests a change in an access level of the IED;
comparing a text input to a password associated with a maximum access setting corresponding to a maximum access level that a user is allowed to reach in the IED to determine whether a user is authorized to request the change in the access level; and
determining whether the access control command should be permitted to alter the access level based on the one or more access control variables regardless of the maximum access level indicated by the maximum access setting associated with the password.
