Introduction

       Advantech WebAccess/SCADA is a 100% web-based SCADA software solution/IIoT platform with open interfaces for developing IoT applications aimed at various vertical markets. It also acts as a gateway for collecting data from ground equipment and transferring the data to cloud applications via MQTT publish/subscribe. In addition to traditional SCADA functions, WebAccess/SCADA features an HTML5-based intelligent dashboard that enables cross-platform, cross-browser data analysis. The basic components of WebAccess/SCADA are as follows: 1. Project Node: This is the project development platform. It also acts as a web server for all clients to connect to development projects, thus facilitating remote monitoring and system control. All system configuration settings, project database files, and graphics are stored in this node. 2. SCADA Node: With various built-in device drivers, this node enables real-time communication with and control over automation equipment via serial, Ethernet, or proprietary communication protocols. It also provides real-time data access for all remote clients. 3. ViewDAQ Client: Through Microsoft Internet Explorer's ActiveX control, ViewDAQ Client monitors and controls the SCADA node. Clients must first connect to the project node to obtain the SCADA node address before they can communicate directly with the SCADA node. Data can be visualized in real time as dynamic graphics, presenting historical trends and alarm information for the user. ViewDAQ Client can be used to acknowledge alarms and adjust set-point data, status data, and other information. 4. Dashboard Client: This enables users to access the dashboard server via any browser on any platform (e.g., computer, pad, or smartphone) with iOS, Android, or Windows. 5. WebAccess APP: This provides a new interface for displaying usage information. Connecting to the WebAccess server enables users to perform remote monitoring of control points and alarms while visualizing trends and communication statuses via the dashboard. Additionally, it provides push notifications for mobile devices.

Feature Details

100% Web-Based Architecture

      WebAccess/SCADA is a 100% web-based SCADA software application. As Advantech’s core IoT application platform, it provides a unique environment for development and remote maintenance, allowing access to and manipulation of data stored on a central server. This enables the configuring, changing/updating, and remote monitoring of equipment, projects, and systems worldwide via a standard web browser, thus saving time that would otherwise be required for system development. WebAccess/SCADA Professional comes with 1,024 clients at no extra cost, which, compared to other similar products, can save a considerable amount of money for system integrators. For edge computing application, WebAccess/SCADA also publishes real-time and historical data to private/ public cloud platforms via MQTT, thus providing a database for big data intended for use in cloud applications.

WebAccess/Dashboard 2.0

       With the functions of the original Dashboard, WebAccess/Dashboard 2.0 uses web services based on Node.js® as the underlying data transport layer, enabling immediate data transfer to clients. In addition to obtaining data from WebAccess, the dashboard can also access data on standard SQL database management systems (SQL Server, MYSQL, ORACLE), and the web service interface can be used to acquire data from other software systems. WebAccess/Dashboard 2.0 also comes with a dashboard editor for creating custom information pages that display analysis charts and diagrams. In addition to more than 40 built-in widgets, Dashboard 2.0 comes with Widget Builder, a widget development tool that aids users in creating unique widgets. Once dashboard screens have been created, users can conveniently utilize the dashboard viewer to access data from different devices via different browsers.

Supports Multiple Drivers

       WebAccess/SCADA supports hundreds of devices. In addition to supporting Advantech I/O devices and controllers, it supports all major programmable logic controllers, controllers, and I/O devices by manufacturers such as Allen Bradley, Siemens, LonWorks, Mitsubushi, Beckhoff, and Yokogawa. For vertical market applications, WebAccess/SCADA supports the DNP 3.0 protocol, which was developed for the power and energy industry. It also supports standard protocols such as Modbus, OPC DA, and OPC UA, and can be easily integrated with other SCADA software. All of these device drivers are integrated into WebAccess/ SCADA at no extra cost. Please refer to the driver list for information on supported devices.
