A1A2CLTR
Signal if a bus-section coupler connection exists between bus sections A1
and A2.
VPA1A2TR
The switch status of A1A2_DC is valid.
EXDUP_BS
Signal if no transmission error from the bay containing the above infor-
mation. This signal is taken from the data valid output on the command
function block.
For a bus-coupler bay in section 1, these conditions are valid:
DCCLTR (A1A2)
DCCLTR (B1B2)
BCABCLTR (sect.2)
VPDCTR (A1A2)
VPDCTR (B1B2)
VPBCABTR (sect.2)
EXDUP_DC (A1A2)
EXDUP_DC (B1B2)
EXDUP_BC (sect.2)
Fig. 18 Signals to a bus-coupler bay in section 1 from a bus-coupler
bay in an other section
For a bus-coupler bay in section 2, the same conditions as above are valid
by changing section 1 to section 2 and vice versa.
If there is no bypass busbar and therefore no Q20 and Q7 disconnectors,
then the interlocking for Q20 and Q7 is not used. The states for Q20, Q7,
Q75, BC_AB are set to open by setting the appropriate module inputs as
follows. In the functional block diagram, 0 and 1 are designated 0=FIXD-
OFF and 1=FIXD-ON:
• Q20_OP = 1
• Q20_CL = 0
• Q7_OP = 1
• Q7_CL = 0
• Q75_OP = 1
• Q75_CL = 0
• BC_AB_CL = 0
