Title:
SCADA WEB HMI SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/070315
Kind Code:
A1
Abstract:
This SCADA web HMI system dynamically distributes, from web HMI servers to HMI clients, server connection priority lists in accordance with an allocation order considering load distribution. Accordingly, pre-setting for the connection priority is not required for the HMI clients. In addition, since the server connection priority list is allocated to each HMI client according to the allocation order considering the load distribution, the number of clients connected to each web HMI server is uniform to attain the load distribution. The SCADA web HMI system can reduce an operation cost required for setting the clients, while attaining the redundancy and load distribution of the servers.
