†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 Chapter
3.4.4 for the way how to connect.
Operate condition
(iii)
Figure 3.4-8 shows the operate condition logic of the LEDR function, which is used to determine
a reset-condition for the operation.

Note: If the event "device-travelling" is detected in the CMNCTRL function, it
*3
indicates that another operator is changing the status of a device. Thus, the IED
should inhibit the operation of any device for the duration that the event is
detected. The detecting signal is denoted as "Traveling OR" in Table 3.4-1.
Note: Criteria "unmatched conditions" are decided when the "Test-bit status" in a
*4
command is not identical to the "IED test status".
Note: The user must program the PLC logic for "Control hierarchy condition". The
*5
user 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.
Settings in LED logics
3.4.4
The user can program the status and the signal of the LED, so that the LEDs are possible to
switch off upon occurrence of the reset. As shown in the logic relating to the LED†, each logic
has a timer and a setting; accordingly, setting Latch should be set for the operation of the
LEDR function. Additionally, the user should connect the signal LED_RST_CMD with the LED
logic.
