GE Multilin F60 Feeder Protection System 5-2075 SETTINGS 5.7 INPUTS/OUTPUTS55.7.2 VIRTUAL INPUTSPATH: SETTINGS ÖØ INPUTS/OUTPUTS ÖØ VIRTUAL INPUTS Ö VIRTUAL INPUT 1(64)There are 64 virtual inputs that can be individually programmed to respond to input signals from the keypad (via the COM-MANDS menu) and communications protocols. All virtual input operands are defaulted to “Off” (logic 0) unless the appropri-ate input signal is received.If the VIRTUAL INPUT x FUNCTION is to “Disabled”, the input will be forced to off (logic 0) regardless of any attempt to alter theinput. If set to “Enabled”, the input operates as shown on the logic diagram and generates output FlexLogic™ operands inresponse to received input signals and the applied settings.There are two types of operation: self-reset and latched. If VIRTUAL INPUT x TYPE is “Self-Reset”, when the input signal tran-sits from off to on, the output operand will be set to on for only one evaluation of the FlexLogic™ equations and then returnto off. If set to “Latched”, the virtual input sets the state of the output operand to the same state as the most recent receivedinput.The self-reset operating mode generates the output operand for a single evaluation of the FlexLogic™equations. If the operand is to be used anywhere other than internally in a FlexLogic™ equation, it willlikely have to be lengthened in time. A FlexLogic™ timer with a delayed reset can perform this function.Figure 5–112: VIRTUAL INPUTS SCHEME LOGIC VIRTUAL INPUT 1VIRTUAL INPUT 1FUNCTION: DisabledRange: Disabled, EnabledMESSAGE VIRTUAL INPUT 1 ID:Virt Ip 1Range: Up to 12 alphanumeric charactersMESSAGE VIRTUAL INPUT 1TYPE: LatchedRange: Self-Reset, LatchedMESSAGE VIRTUAL INPUT 1EVENTS: DisabledRange: Disabled, EnabledNOTEVIRTUAL INPUT 1FUNCTION:VIRTUAL INPUT 1 ID:“Virtual Input 1 to OFF = 0”“Virtual Input 1 to ON = 1”ANDANDANDORSETTINGSETTINGEnabled=1Disabled=0(Flexlogic Operand)Virt Ip 1827080A2.CDRSETTINGVIRTUAL INPUT 1TYPE:LatchedSelf - ResetRSLatch
