The binary inputs 5 and 6 of the additional card X110 are used for busbar disconnector
(DCSXSWI1) or circuit breaker truck position indication.

The binary inputs 7 and 8 (X110:11-13) are for the position indication of the line side
earthing switch.
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 breaker truck and earthing switch position statuses and the statuses
of the master trip logics and gas pressure alarm and circuit breaker spring charging.
The OKPOS output from the DCSXSWI block defines if the disconnector or breaker
truck is definitely either open/in test position or close/in service position. This,
