INSTRUCTIONS: [Technical field to which the invention pertains] The present invention relates to a control system, and more particularly to a tandem control system in which a single "line is connected in series and has a feedback mechanism. ^ [Prior Art] Please refer to FIG. As shown, the conventional-host i controls the control systems of the majority of the slaves 10, 12 14 16 'mainly connected in a dendritic manner in a parallel manner' when the host i wants to control a certain slave, for example, the slave W As long as the launching machine 1G can correspond to the pure control dragon number, the corresponding slave 10 will be activated, and at the same time feedback _ signal informs the host i that it has been activated, but most of them are only one of the CPU and the slave in the host. One of the CPUs confirms that the mutual transmission is correct, and whether the controlled object is actually operated or not is often ignored. The conventionally known conventional control methods mostly use Rs_232 or RS 485 transmission methods, such as the one shown in Figure 1. The distribution connection status is because each of the sub-machines 1G, 12, 14, and 16 must be individually wired. When there are a large number of sub-machines in the system, the (four) line material wiring becomes very large (four), so the wiring cost is quite high, and its so-called Feedback The system is actually a dummy as described above. "Because it is reasonable to say that the corresponding controlled production of the child machine 1G must be completed after the completion of the operation" can only feedback the signal S to the host i has been completed, but the conventional example shown in Figure 1 The dendritic distribution state is usually after the receiving end of the internal CPU of the slave 10 receives the control signal of the host, and the transmitting end of the internal CPU of the slave 1 immediately feeds back a signal to notify the host i that it has received The information, therefore, whether the object driven by the corresponding child machine 1G has been successfully completed, it is not known, so it is good to know the feedback mechanism, but it is only for the signal transmission and appeal. So how Improving the authenticity of the control system has become a subject of active research and development in the industry. [Invention] Therefore, the object of the present invention is to provide a single control system that can effectively implement the feedback mechanism.
