Abstract

PURPOSE: To control data effectively on a system which controls a plant by inputting data from the plant to a CPU, by sending a time signal of a change in state to the CPU in addition to data on a change in state and its address signal.
CONSTITUTION: In the system equipped with a plural number of input devices D1 to Dn supplied with data, input controller 4 controlling those devices D1 to Dn, and CPU2 connected to controller 4, a detection circuit provided to each input device detects the change in state when occurring to one of plant contacts S1 to Sn, an interruption signal is sent from a request-to-interrupt signal generating circuit provided to the input device to bus 5 to interrupt CPU2, and at the same time, an interruption set signal is transmitted to a reception circuit provided to the input device. Then, timer counter TC counts a time signal indicating the time for data inputting and a request-to-interrupt signal from timer T provided to controller 4, whose output is transmitted to CPU2 via a gate circuit provided to the input device together with a data signal, address signal and time signal.
