Appreciate if any of the guru's here can explain what is happening with the addressing as per attachment, B83:51 and at the NEQ instruction in attachment 2.
The instruction is comparing the value of a word in B83 to 0. The word being compared depends on the value of the counter accumulator.
For instance if C85:0.ACC = 5 then the NEQ instruction will be true when B83:5 <> 0. When C85:0.ACC = 20 the NEQ instruction will be true when B83:20 <> 0.
B83:51/[N90:100] works the same way except that in this case the value of N90:100 determines the bit that is examined in word B83:51.
For example if N90:100 = 6 then the XIC (NO) contact will be true when B83:51/6 = 1.
