Interlocking
The signals from other bays connected to the bus-coupler module
ABC_BC are described below.
To derive the signals:
BBTR_OP
Signal if no busbar transfer is in progress concerning this bus coupler.
VP_BBTR
The switch status of BBTR is valid.
EXDUP_AB
Signal if there is no transmission error from any bay connected to the AB
busbars.
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:
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)
