Abstract
The SCADA web HMI client device runs a plurality of web browsers communicating with a web server. A first web browser is displayed on first monitor and draws an HMI screen for monitoring and controlling an industrial plant. A second web browser is displayed on a second monitor and draws the HMI screen. An operation right table is obtained from the web server. If, in the operation right table, the first web browser is not permitted to operate the HMI screen, an operation part positioned on the HMI screen of the first web browser is drawn in an inoperable state. If, in the operation right table, the second web browser is permitted to operate the HMI screen, the operation part positioned on the HMI screen of the second web browser is drawn in an operable state.
