a) ENERVISTA SECURITY
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a substa-
tion and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security management
system is disabled by default to allow the administrator direct access to the EnerVista software after installation. It is recom-
mended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
b) PASSWORD SECURITY
Password security is a basic security feature present in the default offering of the product.
Two levels of password security are provided: command and setting.
The following operations are under command password supervision:
• Changing the state of virtual inputs
• Clearing the event records
• Clearing the oscillography records
• Changing the date and time
• Clearing energy records
• Clearing the data logger
• Clearing the user-programmable pushbutton states
The following operations are under setting password supervision:
• Changing any setting
• Test mode operation
The command and setting passwords are defaulted to “0” when the relay is shipped from the factory. When a password is
set to “0”, the password security feature is disabled. As shown in the figures, the window indicates when the password is at
the default and when the password has been set.

The M60 supports password entry from a local or remote connection. Local access is defined as any access to settings or
commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote
access is defined as any access to settings or commands via any rear communications port. This includes both Ethernet
and RS485 connections. Any changes to the local or remote passwords enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the correspond-
ing connection password. If the connection is to the back of the M60, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password applies.
Events are logged in the Event Recorder. The FlexLogic operands and events are updated every five seconds.
c) CYBERSENTRY SECURITY
CyberSentry Embedded Security is a software option that provides advanced security services. When this option is pur-
chased, the basic password security is disabled automatically.
