Note: "Double Command Blocking" (DCB) is an operation philosophy in the common
1
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 4.2-5. For more information, see Chapter
monitoring application
Note: Detection of event "device-travelling" signifies that other operators are changing
2
the status of one or more devices. Thus, device operation by the IED should be
inhibited whilst ever the event is being detected. The detection signal is denoted
as "Travelling OR" in Table 4.2-5.
Note: If an IED in the process of issuing a trip command, all control operation is blocked
3
until the trip operation has been completed. When the IED has trip circuit
function, the trip command is issued at PLC monitoring point "GEN.TRIP" (see
Table 4.2-5, and p. 265).
Note: The criteria "unmatched conditions" is determined when "Test-bit status" in a
4
command is not identical to "IED test status".
Note: The "Event suppression" function can detect chattering in BI circuits. (See
5
Chapter 4.2.6(i)-3)
Note: A supervision of the Binary IO module can detect connection errors for BI circuits.
