Abstract

PURPOSE: To shorten the time wasted by fruitless arithmetic of a control part by providing a transmission decision part to a data processor, and then to make use of the made free time for another processor.
CONSTITUTION: A process state from control process 6 is inputted to information processor 2 by way of information transmitter 5 on a controlled side, transmission line 4 and information transmitter 3 on a control system side. Between data transmission part 7 and state change detection part 9 connected to the output of input part 10 of this processor 2, transmission decision part 8 is provided; and up-to-date information inputted during a one-cycle period of transmission is compared with information inputted in a one-cycle period preceding by one cycle to decide upon whether a state changed or not. Only when no state change is found by this comparison while a state change is found by previous comparison, information on the state change is outputted to reduce the time for fruitless arithmetic of control part 1.
