PURPOSE:To realize the production of a program in a form wich is coincident with a sequence circuit diagram, by defining the flow of the electric signal just from left to right on the sequence circuit diagram and then storing the arithmetic result into a register. CONSTITUTION:A desired sequence instruction is read out of a sequence program memory part 3, and a sequence process is carried out through an arithmetic circuit 4. In this case, both the relay contact and the output are written on a lateral line between the adjacent longitudinal lines of a matrix. At the relay branch points, a sequence program produced under the conditions that defines the flow of the electric signal just from left to right on a sequence circuit diagram is previously stored in the part 3. Thus an arithmetic process is carried out by the sequence program, the circuit 4 plus AND, OR and line number registers 106, 107 and 108 respectively.
