Functional diagrams for control and interlocking

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 are connected to DCSXSWI1 and ESSXSI1 respectively.
