PURPOSE:To quickly process the column cyclic operation with software by compiling instruction words of a relay ladder diagram into instruction words of a CPU. CONSTITUTION:An instruction word having parameters which correspond to respective elements of a relay ladder in 1:1 is generated. (n) indicates 128-kinds of byte address 00H-7FH of all contacts, and (b) indicates 8 kinds of bit address 0-7 of all contacts. The instruction word to load parameters of said instruction word to registers (omitted in the figure) and instruction words to call subroutines of a sequence program are generated, and these instruction words are compiled.
