Abstract
PURPOSE:To arrange PIO signals suitable for the hardware with smooth designing, by avoiding mutual effect between the physical arrangement of a process input and output signals and the logical arrangement on the software. CONSTITUTION:Pij is the physical arrangement of a process input and output device PIO signal groups, Lkl is the logical arrangement of the PIO signal groups, and (f) is the conversion matrix converting the Pij and the Lkl mutually. The PIO signal groups P1, P2-Pn are converted into the physical arrangement on the software with Lkl=f(Pij) represented with the physical arrangement Pij. Thus, in the design of the software group when the PIO signals are accessed, the design is possble with the logical arrangement Lkl and the physical arrangement Pij can be determined independently of the physical arrangement Lkl. If the arrangement change of the PIO signals takes place, only the part of the converting matrix (f) can be changed.
