To derive the signals:
These signals from each line bay (ABC_LINE), each transformer bay (AB_TRAFO),
and each bus-coupler bay (ABC_BC) are needed:
6LJQDO
ABCDC_OP
Signal if all disconnectors of this busbar section are open.
VP_ABCDC
The switch status of ABCDC is valid.
EXDUP_BB
Signal if no transmission error from any bay containing the above informa-
tion.
6LJQDO
Q1OPTR
Signal if Q1 is open.
Q2OPTR
Signal if Q2 (AB_TRAFO, ABC_LINE) is open.
Q20OPTR
Signal if Q2 and Q20 (ABC_BC) are open.
Q7OPTR
Signal if Q7 is open.
VPQ1TR
The switch status of Q1 is valid.
