If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtain
setting access, then the UNAUTHORIZED ACCESS message is displayed on the front panel.
• REMOTE SETTING AUTH: This 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
provided. If this setting is any other FlexLogic™ operand, then the operand must be asserted (set as on) prior to pro-
viding the remote setting password to gain setting access.
• 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™ oper-
and 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 time-
out 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 Authorization 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 Authorization Timeout setting represents the timeout delay remote setting access. This setting is applicable
when the Remote Settings Authorization 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 per-
mitted and the timer programmed with the Access Authorization 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.
