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
provided. 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.
If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.

ACCESS AUTH TIMEOUT — This setting represents the timeout delay for local setting access. This setting is applicable
when the
LOCAL SETTING AUTH setting is programmed to any operand except “On.” The state of the FlexLogic operand
is monitored continuously for an off-to-on transition. When this occurs, local access is permitted and the timer
programmed 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 updates every five 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 interface) 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 provided. If this
setting is any other FlexLogic operand, then the operand must be asserted (on) prior to providing the remote setting
password to gain setting access.
The Access Authorized Timeout setting represents the timeout delay remote setting access. It applies when the Remote
Settings Authorized setting is programmed to any operand except “On” or “Off.” The state of the FlexLogic 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 denied immediately. 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 updates every five seconds.
5.3.1.3 EnerVista security
Enable the security management system
The EnerVista security system allows an administrator to manage access privileges of multiple users of EnerVista.
It is disabled by default to allow access to the device immediately after installation. When security is disabled, all users
have administrator access. GE recommends enabling the EnerVista security before placing the device in service.
