[@Steve Bailey please confirm this is correct; it is not my specialty but it seems to be an straightforward case of bookkeeping]

Sorry I did not look as deeply as I could have:
  • Create a new rung in A-B software
  • Click on the rung number on the left
  • Hit Enter
  • Type in either
    • COP R05001[R07003] R06000[0] 1
      • A-B Source (part 1) R05001 is analog to Fanuc SR
      • A-B Source (part 2) R07003 is zero-based analog to Fanuc one-based SNX
      • A-B Dest (part 1) R06000 is analog to Fanuc DS
      • A-B Dest (part 2) 0 is zero-based analog to Fanuc one-based DNX (1)
      • A-B Length 1 is analog to Fanuc N (1)
      • N.B. Assumes R05001 and R06000 are arrays of INTs, and R07003 is an INT tag
  • Or, as @Steve Bailey noticed ARRAY_MOVE is being used because indirect addressing is unavailable in Fanuc-land, type in
    • MOV R05001[R07003] R06000
      • N.B. Assumes R05001 is an array of INTs, and R07003 (zero-based) and R06000 are INT tags
      • N is ignored because it is 1 and implicit in MOV
  • Hit Enter again
  • N.B. R07003 will probably be zero-based in A-B
COP (or CPS) is the closest thing to ARRAY_MOVE; MOV also works in this particular case because Fanuc N is 1.


i) Take care of the bits, and the bytes will take care of themselves.
ii) There is no software problem that cannot be solved with another layer of indirection.
