SECURITY
CyberSentry or basic security applies, depending on purchase. This section outlines password access. See the next sec-
tion and the Security chapter for information on setting up user accounts and CyberSentry security.
For the
ACCESS LEVEL
, the "Restricted" option means both settings and commands can be accessed, but there is no
access to factory configuration.
The "Factory Service" level is not available and intended for factory use only.
Two levels of password security are provided via the
ACCESS LEVEL
setting, setting and command, for which you set a
password for each. Use of a password for each level controls whether users can enter commands or change settings.
Another option is to specify setting and/or command access for individual user accounts.
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 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.
The T35 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 T35, the remote password must be used. If the connection
is to the RS232 port of the faceplate, the local password must be used.
The
PASSWORD ACCESS EVENTS
settings allows recording of password access events in the event recorder.
The local setting and command sessions are initiated by the user through the front panel display and are disabled either by
the user or by timeout (via the setting and command level access timeout settings). The remote setting and command ses-
sions are initiated by the user through the EnerVista UR Setup software and are disabled either by the user or by timeout.
