CHAPTER 5: SETTINGS INPUTS/OUTPUTSB30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 5-2635OUTPUT H1a OPERATE: “VO1”OUTPUT H1a RESET: “VO2”5.9.4 Virtual outputsSETTINGS INPUTS/OUTPUTS VIRTUAL OUTPUTS VIRTUAL OUTPUT 1(96)The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs includesignals generated by the local user interface. The virtual outputs are outputs of FlexLogic equations used to customize thedevice. Virtual outputs can also serve as virtual inputs to FlexLogic equations.There are 96 virtual outputs that can be assigned using FlexLogic. If not assigned, the output is forced to ‘OFF’ (Logic 0). AnID also can be assigned to each virtual output. Virtual outputs are resolved in each pass through the evaluation of theFlexLogic equations. Any change of state of a virtual output can be logged as an event if programmed to do so.For example, if Virtual Output 1 is the trip signal from FlexLogic and the trip relay is used to signal events, the settings isprogrammed as follows:VIRTUAL OUTPUT 1 ID: "Trip"VIRTUAL OUTPUT 1 EVENTS: "Disabled"5.9.5 Resetting5.9.5.1 Enhanced and standard front panelsSETTINGS INPUTS/OUTPUTS RESETTING5.9.5.2 Graphical front panelSETTINGS INPUTS/OUTPUTS RESETTINGSome events can be programmed to latch the front panel LED event indicators, target messages, and/or graphical frontpanel annunciator windows. Once set, the latching mechanism holds the latched indicators, messages, or windows in theset state after the initiating condition has cleared until a RESET command is received to return these latches (not includingFlexLogic latches) to the reset state where the initiating condition has cleared. The RESET command can be sent from thefront panel RESET button, a remote device via a communications channel, or any selected operand. The Modbus executefunction 05h with operation code 1 command is also available to perform the same function as the front panel RESET key.RESET OPERAND — The three sources of RESET commands each activates the RESET OP FlexLogic operand. Each individualsource of a RESET command also activates its individual operand RESET OP (PUSHBUTTON), RESET OP (COMMS), or RESET OP (OPERAND) toidentify the source of the command. Each of these three operands generates an event in the event record when activated.The RESET OPERAND setting here selects the operand that activates the RESET OP (OPERAND) operand.RESET ANNUNCIATOR — Used to select a FlexLogic operand that when activated acknowledges/resets all annunciatorwindows on the graphical front panel. The other methods to acknowledge/reset annunciator windows include:• On the displayed page, press the RESET pushbutton with none of the annunciator windows selected to acknowledge/reset all annunciator windows on that page VIRTUAL OUTPUT 1 VIRTUAL OUTPUT 1 IDVirt Op 1Range: up to 20 alphanumeric characters VIRTUAL OUTPUT 1EVENTS: DisabledRange: Disabled, Enabled RESETTING RESET OPERAND:OffRange: FlexLogic operand RESETTING RESET OPERAND:OffRange: FlexLogic operand RESET ANNUNCIATOR:OffRange: FlexLogic operand
