As a consequence of sending interlocking information to remote end, also receiving of
same information locally is needed. Therefore, remote feeder ready, remote circuit
breaker open and remote current transformer failure are connected to the binary signal
transfer function outputs. The remote binary transfer output signal is connected to the
binary output X110:SO3.

Two types of disconnector and earthing switch function blocks are available.
DCSXSWI1...3 and ESSXSWI1...2 are status only type, and DCXSWI1...2 and
ESXSWI1 are controllable type. By default, the status only blocks are connected in
standard configuration. The disconnector (CB truck) and line side earthing switch
status information is connected to DCSXSWI1 and ESSXSI1.

Figure 37: Earth switch 1 control logic
The circuit breaker closing is enabled when the ENA_CLOSE input is activated. The
input can be activated by the configuration logic, which is a combination of the
disconnector or circuit breaker truck and earth-switch position status, status of the trip
logics and remote feeder position indication. Master trip logic, disconnector and
earth-switch statuses are local feeder ready information to be sent for the remote end.
The OKPOS output from DCSXSWI defines if the disconnector or circuit breaker
truck is either open (in test position) or close (in service position). This, together with
the open earth-switch and non-active trip signals, activates the close-enable signal to
the circuit breaker control function block. The open operation for circuit breaker is
always enabled.
