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 the
standard configuration. The disconnector (CB truck) and line side earthing switch
status information are connected to DCSXSWI1 and ESSXSI1.

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
