Abstract

PURPOSE: A sequence device capable of easy assembling relay sequences at low cost by the screen image of sequence such as CRT etc. without the necessity of a great number of memory, by means of setting up a column register which stores ON and OFF state at the interchange point of a sequence.
CONSTITUTION: A sequence instruction memorized in a main memorizing part 4 is read in sequence, and is stored in an instruction register 150. A number part 142 of the instruction register is connected to an input part 1, an output part, and a column register 151. The input part 1 sends the information of the input point appointed by the number part 142 to an AND gate 152. The output part 2 sends the output of an AND gate 153 to the output point appointed by the number part 142. The column register 151 is composed of a flip-flop of one bit, and memorizes ON and OFF state of the interchange point of the sequence.
