Abstract
PURPOSE: To obtain a sequence control unit which can be easily corresponded to the relay sequence in programming by storing the content of arithmetic register for each program step in the linear number status memory.
CONSTITUTION: The data is read from the input-output control unit 1 according to the content of program read from the program memory 2, operated one bit in the arithmetic and control unit 3, and its result is transfered to the input-output control unit 1. The linear number status memory 10 contains addresses of the number equal to that of the program memory 2, and writes the content of arithmetic register 8 in the same address location as that of the program address for each completion of program step. The content of memory 10 can be read at any program step and can be handled like an ordinary input-output data.
