Abstract
PURPOSE: To exchange data without intermittent computing processing operation, by changing over a data memory effective for a computing processing portion and a data memory effective for a data exchange device at a fixed period.
CONSTITUTION: When the initial condition of input and output elements are written in to data memories 22, 23 and the reading of a sequence program is started, a flip-flop FF1 is inverted, a computing processor 30 can read and write in data to the data memory 22 and a data exchange device 24 to the data memory 23, and a signal from the memory 23 is transferred to input and output units 11, 12. When the sequence program is executed at a time, the flip-flop FF1 is again inverted, and the computing processor 30 and the data exchange device 24 are each connected to the memories 22, 23.
