CYAN Intelligent Utilizes WebAccess/SCADA to Build a Data Acquisition and Remote Management Platform for a Wafer Probing Factory
IntroductionWith the advent of industrial IoT and Industry 4.0, manufacturing has entered a fourth revolution. The gradual transformation of typical factories into intelligent ones has become a trend in manufacturing industries worldwide. Data is a core element in this transformation process. However, data acquisition can be surprisingly difficult in many factories. This is because many machines and controllers use a closed architecture and require specific drivers for data acquisition.
By supporting hundreds of controllers and open databases, Advantech’s WebAccess/SCADA can easily resolve data acquisition bottlenecks. This fully web-based SCADA software provides flexibility in accessing management systems to derive information or generate reports via a standard browser on a range of devices. System integrators can also benefit from the various development tools that come with WebAccess/SCADA by shortening development times, thus assisting factories in successfully collecting data and building a remote management platform under their existing architecture.
System RequirementsWISE-PaaS Alliance, CYAN Intelligent was recruited for this project. After a detailed study of the existing operations, CYAN Intelligent found that the wafer probing factory’s OMRON controllers had up to 30 production steps. However, because the data from these controllers could not be imported into the SQL Server database, engineers could not utilize the data for a process analysis. Moreover, because all collected data were imported to a single PC, data access was very limited. To solve these problems, CYAN Intelligent hoped adopted SCADA software to develop a suitable management system.The SCADA software required by CYAN Intelligent must provide the following functions:
- Support for OMRON controllers in order to
collect production information
- Support for a standard database access interface
in order to import production data into the SQL Server database
- Cross-platform architecture for users to obtain data or reports at any time and from any location
- Provide an authorization mechanism to protect confidential
- Development tools for creating GUIs and generating reports according to customer requirements.
In addition to SCADA functions, WebAccess/SCADA offers many useful development tools. In this project, the Dashboard’s built-in ready-made library and support for the TclScript programming language, which has a simple syntax, were the ideal tools for the visualizing information and generating reports while expediting system development. According to their needs, developers can directly select static or dynamic graphics from the dashboard system, and then design a vivid GUI through a simple configuration process. Meanwhile, the system also provides Widget Builder, a tool for developers to customize their own GUI. The easy-to-use TclScript programming tool is particularly convenient for extracting data and generating reports.
