Abstract
PURPOSE: To prevent troubles accompanied with change of input data in the course of operations, by providing two memories where external process input data are stored and by switching and using them for sequence control operations.
CONSTITUTION: Input data DO is input to sequence operation part 20 from input image memory 24 through data bus 22, and the operation result is output through data bus 26. Image memory 24 has a capacity twice or more as large as the number of inputs of input data DI and is divided into two areas. Though contents of image memory 24 are read and rewritten by the address signal from multiplexer 34, they are read only from one area and new input data is written into the other until end signal 42 is output from operating part 20, and therefore, data is not changed in the course of operations.
