Scheme logic
2.23.3
Trip-command collection
(i)
Trip-command grouping gathers the trip signals provided by each protection function and
groups them to the trip operation commands "OPT-TRIP", "OPT-TRIP-A", "OPT-TRIP-B", and
"OPT-TRIP-C" for trip-signal generation, as shown in Figure 2.23-2.
The TRC logic has PLC connection points, which the user can program for issuing the
trip command. For example, if the user wishes to trip the CB using signals generated by
external relays, the signals can be connected to the TRC logic using the following PLC
connection points: TRIP-A_ADD, TRIP-B_ADD, TRIP-C_ADD and TRIP_ADD.
