Note: "Command Blocking" disables any operation except its own; the "Command
1
Blocking" is initiated by the status of "CBK" in a software switch controller
(SOTFSW). The IEC 61850 standard defines "Command Blocking" as "CmdBlk".
For more information on "CBK", see Chapter
Software switch controller. See the signal "
Note: "Double Command Blocking" (DCB) is an operation philosophy. It can be used to
2
protect the substation. The user can program it using GR-TIEMS. The DCB
operating signal is denoted as "DCB RCV OR) in Table 4.1-6.
Note: If the event "device-travelling" is detected, it indicates that another operator is
3
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 "Travelling OR" in Table 4.1-6.
Note: If the issue of a trip command is executed by the IED, any control operation is
4
blocked until the trip operation is completed. If an IED includes a relay
application, the trip command is issued at the output-point "GEN.TRIP" in Table
4.1-6.
Note: Criteria "unmatched conditions" are decided when "Test-bit status" in a command
5
is not identical to the "IED test status".
Note: The "Event suppression" function can detect chattering on BI circuits. (See section
