100% Web-Based Architecture
WebAccess/SCADA is a 100% web-based SCADA software application. As one of Advantech’s core IoT application platforms, it provides a unique environment for development and remote maintenance. All configuration of signals, remote equipment updates, project maintenance, and system monitoring can be done anywhere in the world via a standard web browser.
WebAccess supports real-time data protocols like OPC, Modbus, BACnet, DDE Server and various database such as SQL Server, Oracle, MySQL, and Microsoft Access Database. WebAccess also supports over 200 device drivers that connect to Advantech I/O and controllers, plus all major PLCs, controllers and I/O from Siemens, LonWorks, Mitsubishi, Beckhoff, and more.
WebAccess App is a mobile app for WebAccess/SCADA 8.3 and above based on phones with iOS 10 and Android 5 and above. With Node.js as the underlying data transport layer, data can be immediately transferred to phones. By using the latest WISE-PaaS/Dashboard App together, visualization user experience can be brought to the next level.
WebAccess/SCADA offers several types of interfaces, including RESTful API and SignalR, for various application development. With the Web Service interface, users can integrate WebAccess data into customized apps or applications. MQTT SDK allows customers to exchange data to WebAccess/SCADA without further driver development.
For integration with third-party software, WebAccess/SCADA supports OPC UA/DA, DDE, Modbus, and BACnet server/client for real-time online data exchanges. Through the ODBC interface, WebAccess/SCADA can store historical data in Microsoft SQL Server, Oracle, MySQL, and Microsoft Access for offline data sharing with MES or ERP systems.
For edge computing applications, WebAccess/SCADA also publishes real-time and historical data to private/ public cloud platforms via MQTT, so customers can use various application extensions in their cloud application scenarios.
Advantech’s WebAccess/SCADA ensures continuous reliable communication with automation equipment. The WebAccess backup node activates when the primary node is down. WebAccess/SCADA device drivers are designed to communicate with backup ports and devices whenever the primary connection is lost and to automatically restore to a primary connection when it becomes available.
