Abstract
A SCADA web HMI client apparatus comprises a processor and a memory. The memory stores image data on an HMI screen to supervise an industrial plant, screen operation authority information, and exception information that are received from a web server. The screen operation authority information defines operation permission/prohibition of the HMI screen for each web browser. The exception information defines operation permission/prohibition of each of specific operation parts on the HMI screen for each web browser. The processor executes screen drawing processing in which operation permission/prohibition defined in the exception information is preferentially applied to each of the specific operation parts on the HMI screen, operation permission/prohibition defined in the screen operation authority information is applied to each of operation parts other than the specific operation parts on the HMI screen, and the HMI screen is drawn on the web browser.
