BCABCLTR
Signal if a bus-coupler connection through the own bus coupler exists
between busbar A and B.
BCACOPTR
Signal if there is no bus-coupler connection through the own bus coupler
between busbar A and C.
BCACCLTR
Signal if a bus-coupler connection through the own bus coupler exists
between busbar A and C.
BCBCOPTR
Signal if there is no bus-coupler connection through the own bus coupler
between busbar B and C.
BCBCCLTR
Signal if a bus-coupler connection through the own bus coupler exists
between busbar B and C.
VPBCABTR
The switch status of BC_AB is valid.
VPBCACTR
The switch status of BC_AC is valid.
VPBCBCTR
The switch status of BC_BC is valid.
EXDUP_BC
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.
These signals from each bus-section disconnector bay (A1A2_DC) are also needed. For
B1B2_DC, corresponding signals from busbar 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.
6LJQDO
DCOPTR
Signal if the bus-section disconnector is open.
DCCLTR
Signal if the bus-section disconnector is closed.
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.
