<p>PURPOSE: To improve the data processing efficiency by performing a process output operation only when it is really needed. CONSTITUTION: A remote monitor controller is provided with the state change detection means 23 and 24 which detect the state changes of process input signals in accordance with the types of these input signals, a process input signal storage means 25 which stores the process input signals, and a process input signal control means 23 which stores the process input signals whose state changes are detected by the means 23 and 24 into the means 25. Furthermore, a data processing means 27 is added to process the data on the process input signals stored in the means 25, together with the process signal output means 28 and 29-1 to 29-n which output the process input signals that undergone the data processing through the means 27 to a controlled system as the process output signals.</p> |
