OG exemplary drawing
 
1. A SCADA web HMI system comprising a drawing creating device, an HMI server device, and an HMI client device, the SCADA web HMI system being connected to industrial equipment that constitutes an industrial plant and a line concentrator, wherein:
the drawing creating device is configured to:
display a stencil area where a server part corresponding to the HMI server device, a client part corresponding to the HMI client device, an industrial equipment part corresponding to the industrial equipment, a HUB part corresponding to the line concentrator, and a cable part corresponding to a communication cable are arranged;
display a drafting area where a network configuration diagram showing that the server part, the client part, and the industrial equipment part are connected to the HUB part via the cable part can be drawn by dragging-and-dropping and positioning each part arranged in the stencil area; and
based on the network configuration diagram drawn in the drafting area, generate HMI configuration data associated with vector image information on a system monitoring screen on which parts constituting the network configuration diagram are positioned, IP address information on the parts positioned on the system monitoring screen, and inter-part connection information on the parts positioned on the system monitoring screen,
the HMI server device is configured to:
apply the HMI configuration data to a server runtime library in which monitoring schemes are predetermined for a group of devices including the HMI client device, the industrial equipment, and the line concentrator, thereby executing a system monitoring process for monitoring a communication status of each device of the group; and
transmit a display signal according to the communication status of each device of the group monitored by the system monitoring process, to the HMI client device,
the HMI client device is configured to:
run a web browser,
wherein the web browser is configured to:
draw the system monitoring screen based on the vector image information received from the HMI server device; and
change display statuses of the parts positioned on the system monitoring screen according to the received display signal.
