Interlocking
If the busbar is divided by bus-section disconnectors into bus sections, the
signals BBTR are connected in parallel - if both bus-section disconnectors
are closed. So for the basic project-specific logic for BBTR above, add
this logic:

Fig. 15 Busbars divided by bus-section disconnectors (circuit break-
ers)
The following signals from each bus-section disconnector bay
(A1A2_DC) are needed. For B1B2_DC, corresponding signals from bus-
bar B are used. The same type of module (A1A2_DC) is used for different
busbars, that is, for both bus-section disconnector A1A2_DC and
B1B2_DC.
DCOPTR
Signal if the bus-section disconnector is open.
VPDCTR
The switch status of A1A2_DC is valid.
EXDUP_DC
Signal if there is no transmission error from the bay that contains the
above information. This signal is taken from the data valid output on the
command function block.
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 dis-
connector bay (A1A2_DC), have to be used. For B1B2_BS, correspond-
ing 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.
A1A2OPTR
Signal if there is no bus-section coupler connection between bus sections
A1 and A2.
VPA1A2TR
The switch status of A1A2_DC is valid.
