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 no bus-section disconnector exists the signal DCOPTR, VPDCTR and
EXDUP_DC are set to 1 (FIXD-ON).
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) must be used. For B1B2_BS, corresponding
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.
Q11OPTR
Signal if Q11 is open.
Q12OPTR
Signal if Q12 is open.
VPQ11TR
The switch status of Q11 is valid.
VPQ12TR
The switch status of Q12 is valid.
EXDUP_BS
Signal if there is no transmission error from the bay (bus-section coupler
bay) that contains the above information. This signal is taken from the
data valid output on the command function block.
