5-12 N60 NETWORK STABILITY AND SYNCHROPHASOR MEASUREMENT SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5The following settings are available through the local (front panel) interface only.• LOCAL SETTING AUTH — This setting is used for local (front panel or RS232 interface) setting access supervision. Validvalues for the FlexLogic operands are either “On” (default) or any physical “Contact Input ~~ On” value.If this setting is “On,“ then local setting access functions as normal; that is, a local setting password is required. If thissetting is any contact input on FlexLogic operand, then the operand must be asserted (on) prior to providing the localsetting password to gain setting access.If setting access is not authorized for local operation (front panel or RS232 interface) and the user attempts to obtainsetting access, then the UNAUTHORIZED ACCESS message displays on the front panel.If this setting is "Off," firmware upgrades are blocked. If this setting is "On," firmware upgrades are allowed.• REMOTE SETTING AUTH — This 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 isrequired. If this setting is “Off,” then remote setting access is blocked even if the correct remote setting password isprovided. If this setting is any other FlexLogic operand, then the operand must be asserted (set as on) prior toproviding 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 applicablewhen the LOCAL SETTING AUTH setting is programmed to any operand except “On.” The state of the FlexLogic operandis monitored continuously for an off-to-on transition. When this occurs, local access is permitted and the timerprogrammed with the ACCESS AUTH TIMEOUT setting value is started. When this timer expires, local setting access isimmediately denied. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, thetimeout 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 > ProductSetup > 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 thissetting 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 thissetting is any other FlexLogic operand, then the operand must be asserted (on) prior to providing the remote settingpassword to gain setting access.The Access Authorized Timeout setting represents the timeout delay remote setting access. It applies when the RemoteSettings Authorized setting is programmed to any operand except “On” or “Off.” The state of the FlexLogic operand iscontinuously monitored for an off-to-on transition. When this occurs, remote setting access is permitted, and the timerprogrammed with the Access Authorized Timeout setting value is started. When this timer expires, remote setting accessis denied immediately. If access is permitted and an off-to-on transition of the FlexLogic operand is detected, the timeoutis restarted. The status of this timer updates every five seconds.
