†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 section
3.6.4 for how to connect.
Operate condition
(iii)
Figure 3.6-8 shows the operate condition logic of the LEDR function, which is used to determine
a reset-condition for the operation.

Note: "Command blocking" disables all operation except for its own: the "command
*1
blocking" function is initiated by the status of "S4301" in a software controller
(SOFTSW). The IEC 61850 standard defines the "command blocking" function as
"CmdBlk". For more information on S4301, see Chapter
application: Software switch control function
Table 3.6-2.
Note: "Double Command Blocking (DCB)" is an operation philosophy in the
*2
common control function (CMNCTRL). It can be used to protect the substation.
The user can program it using GR-TIEMS. The DCB operating signal is denoted
as "DCB RCV_OR in Table 3.6-2. For more information, see Chapter
monitoring application: Common controls
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 3.6-2.
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
LEDR function (Function ID: 528001)
