and monitoring application: Automatic sequence control function.
*Note: The LEDR function can run on either “the SBO mode” or “the DIR mode” using a
“ctlmodel” signal when the communication is carried out in the IEC61850; thus,
mapping is required for the IEC61850 communication.
(ii)
Output signal required mapping
The LEDR function can issue a “Select success” signal at the output point
“LEDR01_NSD_CSF”, when the LEDR function determines that the input signal “Select
command (reset)” is true. If the LEDR function determines that the “LEDR01_NSD_CSF” is
not true, the LEDR function returns to the “Wait for a next command” stage.
(iii)
Select condition
Figure 3.6-3 shows the select condition logic in the LEDR function.

*1
Note: “command blocking” disables any operation except its own: the “command
blocking” is initiated by the status of “S4301” in a software controller (SOFTSW).
The IEC 61850 standard defines “command blocking” 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
