Abstract: A relay ladder sequence circuitry having i columns and j rows is divided into a plurality of sections each having a predetermined number of rows, and the bit informations are processed in a parallel manner in the rows of the sections. More specifically, the program in accordance with the sequence ladder construction is memorized and are successively read out as the addresses of the program are appointed. The signals of relay contacts as the bit information are processed for each line in accordance with the read out program, so that a high processing speed is attained.

Abstract: A digital controller for controlling a plurality of processes. In view of the fact that in case a plurality of processes of a like nature are to be controlled, same operands are used for performing a similar arithmetic operation a number of times, instructions are stored in a common memory (1) for simplifying the programming, while the operands are stored in memories (61, 62; 71,72) each incorporated in each of the processors (3, 4) adapted for controlling individually the objective processes, to thereby allow arithmetic processings to be performed by the processors (3, 4) in parallel with one another. Overall processing speed is made thus significantly high.

Abstract: The process control involves feeding in data related to the controlled object and controlling the object according to the data. The total course of the object control is defined using a flow diagram language program (1). Control of the operations of the individual objects is defined using serial programs (31, 41, 51) with contact points built in to allow control according to the results of the flow diagram language program during automatic operation. Manual intervention can be performed via switches during manual operation. USE/ADVANTAGE - The control of processes involving all objects and processes involving individual ones are divided into separate programs, thus increasing productivity, user-friendliness, maintainability and reliability.
