Abstract

PURPOSE:To improve the flexibility of an interlocking control by calculating the algebraic sum of the degree number corresponding to each apparatus, and deciding a classification of a control command to each apparatus by the polarity of the degree number sum and whether an absolute value is large or small. CONSTITUTION:When a degree number matrix is set, addition of the degree number is executed at every apparatus with respect to plural safety signals which have been inputted, the respective algebraic sums are derived, and a safety interlocking control of the apparatus is executed. In case the safety signals are A and B, the degree number sum W1 to the apparatus 1, W2 to the apparatus 2, and W3 to the apparatus 3 become -1+(+1)=0, -1+(+1)=0, and +1+(-1)=0, respectively. Accordingly, between the signals A, B, the first arrival signal takes precedence and the first arrival priority system is realized. On the other hand, when the safety signals and B and C, the degree number sum W1=+1+(-2)=-1, W2=+1+(-2)+-1, and W3=-1+(+2)=+1, and an inter-signal priority system is realized.
