Interlocking
These signals from each line bay (ABC_LINE), each transformer bay (ABC_TRAFO),
and bus-coupler bay (ABC_BC), except the own bus-coupler bay are needed:
6LJQDO
Q1Q2OPTR Signal if Q1 or Q2 or both are open.
VPQ1Q2TR The switch status of Q1 and Q2 are valid.
EXDUP_AB 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.
For bus-coupler bay n, these conditions are valid:
Q1Q2OPTR (bay 1)
Q1Q2OPTR (bay 2)

Q1Q2OPTR (bay n-1)
VPQ1Q2TR (bay 1)
VPQ1Q2TR (bay 2)

VPQ1Q2TR (bay n-1)
EXDUP_AB (bay 1)

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:
