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:
BBTR_OP (sect.1)
DCOPTR (A1A2)
DCOPTR (B1B2)
BBTR_OP (sect.2)
VP_BBTR (sect.1)
VPDCTR (A1A2)
VPDCTR (B1B2)
VP_BBTR (sect.2)
EXDU_12 (sect.1)

section
For a bus-coupler bay in section 2, the same conditions as above are valid by
changing section 1 to section 2 and vice versa.

Signals from bus-coupler

If the busbar is divided by bus-section disconnectors into bus-sections, the signals
BC_12 from the busbar coupler of the other busbar section must be transmitted to
the own busbar coupler if both disconnectors are closed.
