Interlocking
To derive the signals:
A1DC_OP
Signal if all disconnectors on busbar A1 are open.
A2DC_OP
Signal if all disconnectors on busbar A2 are open.
VPA1_DC
The switch status of A1_DC is valid.
VPA2_DC
The switch status of A2_DC is valid.
EXDUP_BB
Signal if there is no transmission error from bay DB (double-breaker bay)
that contains the above information.
These signals from each double-breaker bay (DB_BUS) are needed:
Q1OPTR
Signal if Q1 is open.
Q2OPTR
Signal if Q2 is open.
VPQ1TR
The switch status of Q1 is valid.
VPQ2TR
The switch status of Q2 is valid.
EXDUP_DB
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.
The logic is identical to the double busbar configuration described in
"Signals in single breaker arrangement" on page 28.
