<p>PROBLEM TO BE SOLVED: To provide a sequencer capable of surely and easily compensating the delay of control even in the fluctuation of an input/output responding time. SOLUTION: A remote I/O (input/output device) is provided with a mechanism fold-transmitting input data to a sequencer main body at the time of inputting this data from the sequencer main body, which outputs data for measuring the input/output responding time to the remote I/O after outputting control data, repeatedly measures time until this data is turned back and inputted (S1 to S11), predicts the present state of a device from the changing rate (S13), makes this predicted value the present state of the device (S149, executes arithmetic necessary for controlling the device (S15) and outputs the arithmetic result to the remote I/O device (S16).</p> |
