The
SCADA is Supervisory Control and
Data Acquisition System. These systems will acquisition data
and controls to the devices remotely. All the data from
acquisition, it will be passed to HMI/MMI for
presentation. The HMI/MMI is used to display the remote locations
schematic,display alarms, display trends and penerating the reports.

The
SCADA systems can be integrated with
web technology in a couple different ways. Any client who is in the
network can access the Web SCADA through Web server using
the HTML browsers. The browser that supports HTML rendering can be used
to browse the SCADA system. SCADA server can send email messages or
reports to the specified users. Browser is independent of platform and
can be viewed the SCADA information on any OS or machine platform. For
security reasons, the webserver can be enabled through HTTPS protocol.
