Abstract
PURPOSE:To prevent overtaking of data by adding a processing function of a system notice signal and applying exclusive control to a communication control circuit and a supervising circuit. CONSTITUTION:Exclusive control is applied to the communication control circuit 4 and the supervising circuit 5, a system notice signal 11 to information the status change in the device is added and the operating state of the subsequent station stored in its own station is revised by receiving the system notice signal 11 and sent to a host station. In reading the data of the operating status signal noticed from the communication control circuit 4 detecting the change in the device, the system notice signal is sent from the circuit 5 to the host station and when the signal 11 is a data to be informed further to the host station after the circuit 5 of the host station revises the operating state of the subsequent station stored in its own station, the signal 11 is sent as the system notice signal. Thus, the overtaking of the data is prevented and if the device has a change, it is subject to the transmission/reception signal as the notice signal instantly.
