Figure 2.33-1 shows that the function is made with following logics:
Collection: The signals, received from the various protection functions (shown as
‘FC18’ and others; see Table 2.33-2 and Table 2.33-6), are gathered in the Trip-signal
collection logic.
Generation: CB trip signal generation, Sub-signal generation for blocking ARC§, and
Alarm-signal generation logics are provided.
A binary output (BO†) circuit must be selected in order to energize the trip coil of the
CB#1 and CB#2. That is, the BOs should be made the connection with the CB#1 and CB#2 trip
coils; the drive signal should be outputted (i.e., ‘TRIP-COMMAND1-A,-B,-C’ and ‘TRIP-
COMMAND2-A,-B,-C’†). The Alarm-signal generation logic operates to provide a trigger signal
for the recording function‡.
†Note: The internal connection between the TRC function and the BIO module should be
performed using the BIO settings or the PLC programming. The user can program
the connection the PLC monitoring point ‘TRIP-COMMAND1-A (8000001B20) etc.’
with preferred BO circuits using the settings [Input signal1] etc. of each BO on the
BIO module. The externally wired connection between the BIO module and trip
coil circuit is made at the IED terminals. For more information with regard to the
BO circuit concerning the Element ID (Data ID), see Chapter
