is continuously monitored for an off-to-on transition. When this occurs, local access is permitted and the timer pro-
grammed with the
ACCESS AUTH TIMEOUT
setting value is started. When this timer expires, local setting access is
immediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeout
is restarted. The status of this timer is updated every 5 seconds.
The following settings are available through the remote (EnerVista UR Setup) interface only. Select the
Settings > Product
Setup > Security
menu item to display the security settings window.
The
Remote Settings Authorized
setting is used for remote (Ethernet or RS485 interfaces) setting access supervision. If
this setting is “On” (the default setting), then remote setting access functions as normal; that is, a remote password is
required). If this setting is “Off”, then remote setting access is blocked even if the correct remote setting password is pro-
vided. If this setting is any other FlexLogic operand, then the operand must be asserted (set as on) prior to providing the
remote setting password to gain setting access.
The
Access Authorized Timeout
setting represents the timeout delay remote setting access. This setting is applicable
when the
Remote Settings Authorized
setting is programmed to any operand except “On” or “Off”. The state of the Flex-
Logic operand is continuously monitored for an off-to-on transition. When this occurs, remote setting access is permitted
and the timer programmed with the
Access Authorized Timeout
setting value is started. When this timer expires, remote
setting access is immediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected,
the timeout is restarted. The status of this timer is updated every 5 seconds.
5.2.2 CYBERSENTRY SECURITY
a) SETUP
This section applies if the CyberSentry option is included with your relay.
When first using CyberSentry security, use the following procedures for set up.
First, activate and log in.
1.
Log in to the relay as Administrator by using the Value keys on the front panel to enter the default password
"ChangeMe1#". The "Lock relay" setting needs to be disabled in the
Security > Supervisory
menu. Disabling this set-
ting allows settings configuration and firmware upgrade.
2.
Enable the Supervisor role if you have a need for it.
3.
Log out the Administrator account, then log in as Observer.
Next, device or server authentication can be used. Use device authentication to log in using the five pre-configured roles
(Administrator, Supervisor, Engineer, Operator, Observer). When using a serial connection, only device authentication is
supported. For server authentication, the RADIUS server requires configuration, as outlined here. A window opens when
logging in and allows you to choose the authentication mechanism. The choice of authentication type (server versus
device) and the capacity to configure server parameters are available only in the EnerVista software.
