(ii) Select condition
Figure 3.7-8 shows the select condition logic in the GCNT01 function. The GCNT01 function
checks the condition for the select command using the signal “S4301_STATE” and other signals.
When resetting the counter is performed from the “Statics sub-menu” in the HMI operation†,
the user should set On for scheme switch [GCNT01-HMI].
†Note: The HMI operation is discussed in Chapter User interface: Monitoring sub-menu .

Note: “Command blocking” disables any operation except its own; the “command
blocking” is initiated by the status of “S4301” in a software switch controller
function (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 . (Table 3.7-3)

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. The DCB
operating signal is denoted as “DCB RCB OR” in Table 3.7-3.
3
Note: If the event “device-travelling” is detected, 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 detected. The detected signal is denoted
as “Traveling OR” in Table 3.7-3.
4
Note: Criteria “unmatched conditions” are decided when the “Test-bit status” in a
command is not identical to the “IED test status”.
5
Note: The user will need to program the PLC logic “Control hierarchy condition”. The
user is also required to connect the logic condition with the select condition logic
using the connection pint “GCNT00IN_TMP_51” (see Table 3.7-4). For more
information, see Chapter Control and monitoring application: Control hierarchy .
