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 4.1-5. For more information, see Chapter
monitoring application
Note: If the event "device-travelling" is detected in the CMNCTRL function, it indicates
2
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
detected signal is denoted as "Travelling OR" in Table 4.1-5.
Note: If the issue of a trip command is executed by the IED, any control operation is
3
blocked until the trip operation is completed. When the IED has trip circuit
function, the trip command is issued at PLC monitoring point "GEN.TRIP" (see
Table 4.1-5, and p. 266).
Note: Criteria "unmatched conditions" are decided when "Test-bit status" in a command
4
is not identical to "IED test status".
Note: The function "Event suppression" can detect chattering on BI circuits. (See

Chapter 4.1.6(i)-3)
Note: A supervision of the Binary IO module can detect connection errors for BI circuits
