*1
Note: “Command Blocking” disables any operation except for itself; “Command
blocking” is implemented as “CBK” in a software switch controller (SOFTSW);.
The IEC 61850 defines “Command Blocking” as “CmdBlk”. For more information
of “CBK”, see Chapter
Control and monitoring application: Software switch
control function
. See the signal “CBK_STATE” in Table 4.9-6.
*2
Note: “Double Command Blocking (DCB)” is an operation philosophy. It can be used
to protect the substation. The user can program it using GR-TIEMS.
*3
Note: Detection of event “device-travelling signifies that other operators are
changing the status of one or more devices. Thus, device operation by the IED
should be inhibited whilst ever the event is detected. The detection signal is
denoted as “Traveling OR” in Table 4.9-6.
*4
Note: If an IED is in the process of issuing a trip command, all control operation is
blocked until the trip operation has been completed. If the IED has a relay
application, the trip command is issued at the output-point “GEN.TRIP” in Table
