WebAccess SCADA Software

WebAccess is a browser-based software package for human-machine interfaces HMI, and supervisory control and data acquisition SCADA. It is used to automate complex industrial processes for situations where remote operations are needed. All the features found in conventional HMI and SCADA software packages are available in an ordinary browser including Animated Graphics Displays, Real-time Data Control, Trends, Alarms and Logs.

    A web server for all clients to connect to the development
    project or remotely monitor
    and control the system.

    • System integration

    • Project development

    • Web server, provide connection between SCADA and client

    • Database server, record the data





    It communicates in real-time with automation equipment
    and controls the equipment via serial, Ethernet or proprietary
    communication via multiple built-in device..

    • Connect end devices

    • Data acquisition and transmission

    • Support 200+ device driver

    • Real-time and historical data log

    • Action log




    The client connects to the Project Node and communicates
    directly with the SCADA Node using proprietary
    communications over a TCP/IP connection.

    • Remote monitoring and control

    • Real-time and historical trend

    • Alarm record

    • Monitor via PDA and smart phone






    The Mobile Client interface is intended for use with smart
    mobile devices, such as iOS, Android; and Windows mobile
    devices. In the mobile client users can browse graphics,
    data-log trends, and tag information in real-time. Set value
    to tag or acknowledge alarms can also be supported via an
    intuitive interface.

    • Mobility monitor and control

    • Real-time data







    WebAccess supports multi-touch functionality with various preset
    gestures, such as flick to change pages, zooming in and out of
    the display and 2-handed operation maximizing operating safety,
    increasing usability and decreasing training time due to the more
    intuitive handling.






    WebAccess Scheduler provides on/off control and setpoint
    changes based on the time-of-day, day of week and the calendar.
    Users can control lights, temperature and equipment for saving
    energy during specific days and times. It also allows the definition
    of up to 17 periods per day and preserved function for setpoint.








    WebAccess allows operators and users to monitor equipment and
    facilities directly using web-enabled full-motion video cameras,
    audio, and web cams. The video image appears in the same
    display area as graphics, animation, alarms and trends displays.
    With vector-based graphics, WebAccess graphics can be built at
    any resolution and displayed at any resolution.





    WebAccess provides Historical and Real-Time Trending, Data
    Logging and Centralized Logs. 12 Tags can be added to a Trend
    display without losing the history of the other tags. Real-time
    data, alarms, and operator actions from all SCADA nodes can be
    logged to a central ODBC database.






    WebAccess integrates real-time data on each geographical site with Google Maps. Users can easily associate their real-time site data with a marker and label by right-clicking on their Google Maps or entering the coordinates of the target. This function also integrates with GPS modules to track the location of the marker in Google Maps and allows it to be used in vehicle systems.





    WebAccess Real-Time Database (RTDB) is designed to meet industrial high speed and large quantity data access requirements. Just by enabling the usage of RTDB in WebAccess configuration page, WebAccess SCADA node can serve data processing at a rate of millions of records per second. Also, the RTDB maintenance feature can automatically archive and delete obsolete data.








    Scalable system architecture allows users to run the same database and graphics on Multiple Windows operating systems, such as Microsoft® Windows® XP, XP Embedded, Windows 7, Windows 7 Embedded, Windows 8 Desktop Mode, or Windows CE. WebAccess also supports Mobile app remote monitoring on iPhone or Android operating systems.





    WebAccess supports the following open real-time data connectivity: OPC, Modbus, BACnet, DDE Server and the following open offline data connectivity: SQL Server, Oracle, MySQL, and Microsoft Access Database. WebAccess supports over 200 device drivers. In addition to Advantech I/Os and controllers, WebAccess also supports all major PLCs, controllers and I/Os, like Allen Bradley, Siemens, Lon Works, Mitsubishi, Beck off, Yokogawa etc.






    The Advantech WebAccess Alarm function provides different alarm groups and level settings to inform operators of the status of processes and equipment by sending e-mails, SMS, and audio announcements. Users can define alarm groups, working schedules, and priority settings to deliver alarm messages via SMS, email or audio announcements to multiple receivers.




    Advantech WebAccess assures continuous, reliable communication to automation equipment by SCADA Redundancy. The primary and backup SCADA will communicate with each other when the kernel is started, but only one will communicate to automation equipment. Backup SCADA node activates when the primary SCADA node is down. The Web Browser clients will be redirected to the backup if the primary node fails. Data Logging and Trending files are updated on both primary and secondary, and resynchronized when the Primary returns.
