Abstract

PURPOSE:To prevent circuit for logical operation from being limited even if the number of columns in a corresponding ladder circuit is great, by employing a column cyclic operating method wherein logical operations are provided in succession toward an output side to obtain the output of each digit. CONSTITUTION:With a signal clock 1, contact information and branching information on a column are inputted to shift register respectively. Once information on one column is inputted, an operation result which corresponds to the column is outputted to each row of a register 103 at an output part and its logical value is latched with a signal clock 2 and held for the operation of the next column. Thus, logical operations from the 1st column to the (m)-th column are carried out in a latch mode and then a shift mode beings, outputting values of respective rows of the register 103 as outputs OUT1, OUT2-OUTn synchronizing with the signal clock 2.
