†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
Figure 3.6-8 shows the operate condition logic of the LEDR function, which is used to determine
a reset-condition for the operation.

*1
Note: “Command blocking” disables all operation except for its own: the “command
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
Control and monitoring
application: Software switch control function. See the signal “S4301_STATE” of
Table 3.6-2.
*2
Note: “Double Command Blocking (DCB)” is an operation philosophy in the
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
Control and
monitoring application: Common controls.
*3
Note: If the event “device-travelling” is detected in the CMNCTRL function, it
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.
*4
Note: Criteria “unmatched conditions” are decided when the “Test-bit status” in a
command is not identical to the “IED test status”.
*5
Note: The user must program the PLC logic for “Control hierarchy condition”. The
user must connect that to the select condition logic using the connection point
“LEDR01_CTRL_RIGHT”. For more information, see chapter
Control and
