The present disclosure describes apparatus, methods, and system for secure access control of an intelligent electronic device ('IED') by multiple personnel. Within the IED a set of basic permissions is defined. A software program allows a security administrator create specific roles from the basic permissions. The software program can then be used to assign to a user a specific role for one or more specific IEDs. This action creates a set of unique security keys for the user and a unique security file for each IED. When a user accesses an IED the system identifies the user from the security key and determines his/her permissions using the security file. The security key may take the form of a password inputted into the IED, an access device incorporated within the IED, and/or a remote access device positioned proximate the IED or removably positioned in the IED.

Apparatus, methods, and system for role-based access in an intelligent electronic device

A switch-gear system having a central controller for operating a plurality of circuit breakers, a first interface device, a second interface device, and an update system in communication with the first and second interface devices is provided. The first interface device can modify a lineup parameter of the plurality of circuit breakers in and display a first graphical representation of the lineup parameter. The second interface device can modify the lineup parameter and display a second graphical representation of the lineup parameter. The update system can save a modification to the lineup parameter at the first or second interface device and to publish the modification to the other of the first or second interface devices so that the first and second graphical representations are identical.

Systems and methods for updating graphical representations on multiple interface devices

A method for capturing data includes recording, within an intelligent electronic device (IED), information regarding an initial change to one of a firmware within the IED, a hardware within the IED, and a configuration within the IED.
