Abstract

PURPOSE:To shorten the cycle time by giving the polling only to the terminal unit with switch having constant monitor input and then giving the jump to other terminal units which just give the control to the load respectively. CONSTITUTION:In the master unit which controls plural numbers of terminal units, the received data is not applied directly to received data memory 19 but the detection is given through received data comparing part 26 whether the contents of the return signal from the terminal unit changed or not in comparison with the conventional contents. Then the terminal unit address is stored in transmission request address memory 25. And now if the change of the data contents is detected for the return signal of terminal unit 6, the count value of control address counter 21 is rewritten into the terminal unit address in the scanning sequence of the address preceding one address with switch. Then the terminal unit address is sent to transmission address operation part 24. After this, the control is through with all terminal units by the return signal of the terminal unit with switch whose return signal changed. Then the address of memory 25 is cleared.
