摘要
In the present invention, the SCADA DB processing server is installed in the communication path between the SCADA server and HMI devices, so that the HMI devices are not directly connected to the SCADA server, but connect to the SCADA DB processing server to request database operations and receive the results of database operations. As it is configured to process, the resource usage and load of the SCADA DB server can be significantly reduced. As the DB server of the SCADA server is connected to the SCADA DB processing server with a single cable, the conventional DB server is physically connected with multiple HMI devices. As a result, network management efficiency decreases, and at the same time, the market price and manpower consumption due to network maintenance can be dramatically reduced. The SCADA DB processing server stores software modules and connection information of HMI devices to be connected, When connection information is changed, it is configured to update and save the changed content, thereby maximizing network management efficiency and improving management cost and time consumption. It relates to an HMI&SCADA system that can improve communication speed and significantly reduce failures and errors by optimizing PLC's memory access.
