Therefore, the monitoring method of the automation system of the present invention is applicable to monitoring the plurality of workstations by monitoring the main computer of the automation system - the connection state of the main bus and the secondary bus, and the monitoring method of the automation system comprises the following steps : 1 / (A) The main computer transmits the inquiry signal to the workstations in a multi-guard manner via the main bus and receives the return signals. σ (Β) If the workstation does not return the signal to the main power 5 1273392 brain, the host computer will send the interrogation signal to the workstation again. If there is still no return signal, the workstation is temporarily set offline. And (c) check whether the previous workstation is faulty. If the previous workstation is set to fault, it determines that the main busbar is faulty and switches to the secondary busbar polling: Wait for the workstation. If the previous workstation is normal, set the workstation. malfunction. [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiment. Referring to FIG. 1 and FIG. 2, a preferred embodiment of the monitoring method of the automation system of the present invention is applicable to monitoring the connection state of a main bus bar 4 and a bus bar 5 by a host computer 3 of the automation system 2. In order to monitor the plurality of workstations 6. The monitoring method comprises the following steps: (A) performing steps 701 and 702, the host computer 3 sequentially transmits the inquiry signal to the workstations 6 in a multiplex manner via the main bus bar 4, and receives the return signal. In this embodiment, M workstations are used for description. In the normal case, the host computer 3 sends the inquiry Λ #U 轮 (Polling) workstations 6 in the order of the general bus (by (4) to M), and after receiving the polling inquiry signal, the I station 6 will itself [The data and status of the control are returned within the specified time. • The signal is transmitted back to the main computer 3 via the main bus 4 for storage and display. Where 'the main computer 3 is connected with the main bus bar 4 with its RS_232 sequence output'. If the distance from the workstation 6 is far away, the rs_485 can be connected to enhance the transmission of the signal transmission, and when it reaches each workstation 6, it is switched back to rs_232淳. And the data and status returned by each workstation 6 include the state of its own operation,

In this embodiment, the input and output mode is described as an example, and the manner in which it can be described in the implementation is limited. He passes the wheel mode, and does not perform the above steps (Β) to perform step 703. If the workstation 6 that has not been transmitted back in the wheel is in a certain time ^' tiger to the main computer 3, the main computer 3 performs the step collapse. 7〇5=Send _ signal to the workstation 6, and wait for the return message. If the return message is not sent to the host computer 3, the work is temporarily set to offline. Since there is no response due to polling twice, it may also be a fault on the main bus, so it is only temporarily set to the workstation 6 offline. ★ JO performs step 706 to check whether the previous workstation 6 is faulty, and if the workstation 6 is normal, then the setting of the polling twice does not respond to the work. That is, only one workstation 6 polls twice without a response, and it is determined that the station 6 is faulty, and the host computer 3 also displays the address or name of the faulty workstation 6 'notification for repair. If the former _ wei station 6 has been set to failure, it is determined that the main bus 4 is faulty, and the sub-port 5 is polled to poll the workstations 6, that is, the second workstation 6 is set to offline and fault, then it is determined If the main bus 4 fails, the host computer 3 immediately displays the main bus 4 failure, and performs step 7〇8' to switch to the secondary bus 5 to poll the workstations 6, thereby maintaining the operation of the entire automation system 2. In summary, the monitoring method of the automation system of the present invention utilizes the transmission of the backhaul signals of each workstation 6 in the process of polling each workstation 6, to determine the connection state of the main busbar 4, and not only the workstations 6 but also the workstations. It is also possible to detect the failure of the main bus 4 in a simple manner and switch to the secondary sink in time; the 1273392 flow row 5 maintains the purpose of the overall automation system of the present invention. The present invention is only exemplified by the above-described preferred embodiments of the present invention, and is intended to limit the scope of the present invention, that is, the scope of the invention and the description of the invention.
