DEVICE
NOTE:
4–22
LOGOUT
Range: Yes, No
Default: No
This setting logs out the current user. When logging out from the panel, a switch to the
Observer role is performed.
DEVICE AUTHENTICATION
Range: Yes, No
Default: Yes
Device authentication setting offers the option to disable or enable this type of
authentication. By default device authentication is on, but the option to turn it off is
provided and may be chosen when a RADIUS server is accessible and the user wishes to
use it exclusively and not both types of authentication.
Only an administrator role may change this setting. If administrator disables it, the role
remains logged in, but it is not allowed to write any other settings any more. In EnerVista
a popup window warns the user that such changes are not going to be saved.
If device authentication is disabled, EnerVista still displays both radio buttons for
choosing between device and server authentication. See the EnerVista setup section.
However the drop down menu, when local is selected, has only the Administrator option.
Once logged in, this role is only able to switch on device authentication. After switching
on the device authentication, the Administrator gains write access to all the other
settings without the need to logout and login again.
LOAD FACTORY DEFAULTS
Range: Yes, No
Default: No
An Administrator role is able to change this setting. This resets all the settings,
communication and security passwords, and all records.
ACCESS LOCKOUT
Range: 0-99
Default: 3
The Access lockout is the set number of failed authentications (the default is 3 and the
maximum is 99) before the device blocks subsequent authentication attempts for the
lockout period. A value of "0" means Lockout is disabled.
ACCESS LOCKOUT PERIOD
Range: 0-9999 minutes
Default: 3 minutes
The Access lockout period is the set period of time in minutes of a lockout (the default is
3 and the maximum is 9999). A value of "0" means that there is no lockout period.
Note that the lockout period is measured from the moment the maximum number of failed
authentications has been reached. Additional attempts to login during the lockout period
do not extend this time.
ACCESS TIMEOUT
Range: 2-999 minutes
Default: 5 minutes
The Access timeout is the time of idleness before a logged in user is automatically
logged out. This timeout setting applies to all users, independent of the communication
channel (serial, Ethernet or direct access).
