Scada Web Hmi System

Abstract: This SCADA web HMI system comprises an address diversion source designation means and an address diversion means. The address diversion source designation means designates an existing component on a first screen as an address diversion source for a new component on a second screen, which is an address diversion destination. The address diversion means is used for causing the new component and the existing component to perform the same processing when the existing component is designated as the address diversion source for the new component by the address diversion source designation means. When an address assignment means has already assigned an address to the existing component, the address diversion means diverts the address of the existing component to the new component. A web browser displays an HMI screen, updates the display of the existing component on the first screen and the new component on the second screen according to a common display signal, and transmits operation signals corresponding to operations of the existing component and the new component to a common address of a PLC.
