6F2T0207 (0.01)GRE200 (5,6)- 371 -†Note:Although the “LED_RST_COM” signal is connected previously with several LEDs,by the manufacturer, user can also connect the signal with the LEDs. See Chapter3.4.4 for the way how to connect.(iii) Operate conditionFigure 3.4-8 shows the operate condition logic of the LEDR function, which is used to determinea reset-condition for the operation.Operate conditionLEDR function (Function ID: 528001)To operate logicControl hierarchy (e.g. 43RL) (PLC connection point) *5IED serious error detected[LEDDR1_EN]OnUsers must setup this condition correctlyOther devices traveling detected*3Traveling ORLEDR01_CTRL_RIGHT528001 820701ED50SERI_ERR&&1≥Unmatched condition detected *4Figure 3.4-8 Operate condition logic in LEDR*6*3Note: If the event “device-travelling” is detected in the CMNCTRL function, itindicates that another operator is changing the status of a device. Thus, the IEDshould inhibit the operation of any device for the duration that the event isdetected. The detecting signal is denoted as “Traveling OR” in Table 3.4-1.*4Note: Criteria “unmatched conditions” are decided when the “Test-bit status” in acommand is not identical to the “IED test status”.*5Note: The user must program the PLC logic for “Control hierarchy condition”. Theuser must connect that to the select condition logic using the connection point“LEDR01_CTRL_RIGHT”. For more information, see Chapter 3.3.“LEDR01_CTRL_RIGHT” is provided in Table 3.4-2.3.4.4 Settings in LED logicsThe user can program the status and the signal of the LED, so that the LEDs are possible toswitch off upon occurrence of the reset. As shown in the logic relating to the LED†, each logichas a timer and a setting; accordingly, setting Latch should be set for the operation of theLEDR function. Additionally, the user should connect the signal LED_RST_CMD with the LEDlogic.†Note:For more information on LED logics, see ChapterTechnical description: Humanmachine interface: LEDs (→p. 677).
