(A1A2_DC) is used for different busbars, that is, for both bus-section disconnector
A1A2_DC and B1B2_DC.
Signal
DCOPTR The bus-section disconnector is open.
VPDCTR The switch status of bus-section disconnector DC is valid.
EXDU_DC No transmission error from the bay that contains the above information.
If the busbar is divided by bus-section circuit breakers, the signals from the bus-section
coupler bay (A1A2_BS), rather than the bus-section disconnector bay (A1A2_DC), have
to be used. For B1B2_BS, corresponding signals from busbar B are used. The same type
of module (A1A2_BS) is used for different busbars, that is, for both bus-section circuit
breakers A1A2_BS and B1B2_BS.
Signal
S1S2OPTR No bus-section coupler connection between bus-sections 1 and 2.
VPS1S2TR The switch status of bus-section coupler BS is valid.
EXDU_BS No transmission error from the bay that contains the above information.
For a bus-coupler bay in section 1, these conditions are valid:
