Supervisory control and data acquisition systems in refineries are used to acquire the real-time meter data of each factory to immediately feedback to the management system. The system uses the industry-leading internet configuration software, WebAccess, to build system network of data acquisition and process, utilizing the outstanding network features of WebAccess.
It ensures effective and accurate large scale data acquisition (successfully being applied to 30,000 nodes), and fully supports a remote full-featured client.
Our high-performance UNO-2174A/2178A embedded computer with WebAccess SCADA node in factory works as data communication server of DCS, SIS, PLC, and other systems to integrate and upload data.
After UNO-2174A/2178A unifies protocol, all data goes to factory management workstation (IPC) with WebAccess SCADA node.
At factory management workstation, WebAccess application compiles and sorts data, and upload to redundant and hot-standby server. After building connection, server will acquire data through SCADA node.
If WebAccess remote client-end needs to check onsite data, it can directly check onsite SCADA node which ensures real-time data.
