5-422 L90 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUALTRANSDUCER INPUTS/OUTPUTS CHAPTER 5: SETTINGS55.9.6.2 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• To acknowledge/reset a specific annunciator window, use the Up, Down, Left and Right pushbuttons to select thewindow, and press the RESET or ENTER pushbutton• All annunciator windows can be reset remotely by programming a Virtual Input (for example Virtual Input 1) as theinput to the RESET ANNUNCIATOR setting. Then the Modbus execute function 05h with operation code 1000h command(or function 10h with address 400h) is used to set the state of Virtual Input 1.For the RESET ANNUNCIATOR setting, the RESET ANCTR OP FlexLogic operand is activated by the two sources of RESETcommand, operand source and manual source. Each individual source of a RESET ANNUNCIATOR command also activatesits individual operand RESET OP (OPRD) or RESET ANCTR OP (MNUL) to identify the source of the command. Each of these twooperands generates an event in the event record when activated. The setting here selects the operand that activates theRESET ANCTR OP (OPRD) operand. The RESET pushbutton on the front panel or the reset command from the softwareactivates the RESET ANCTR OP (MNUL) operand.5.10 Transducer inputs/outputs5.10.1 DCmA inputsSETTINGS TRANSDUCER I/O DCMA INPUTS DCMA INPUT H1(U8) RESETTING RESET OPERAND:OffRange: FlexLogic operand RESET ANNUNCIATOR:OffRange: FlexLogic operand DCMA INPUT H1 DCMA INPUT H1FUNCTION: DisabledRange: Disabled, Enabled DCMA INPUT H1 ID:DCMA Ip 1Range: up to 20 alphanumeric characters DCMA INPUT H1UNITS: μARange: six alphanumeric characters DCMA INPUT H1RANGE: 0 to -1 mARange: 0 to –1 mA, 0 to +1 mA, –1 to +1 mA, 0 to 5mA, 0 to 10mA, 0 to 20 mA, 4 to 20 m DCMA INPUT H1 MINVALUE: 0.000Range: –9999.999 to +9999.999 in steps of 0.001
