Java is a widely used, easy to learn and platform-neutral programming language. Even in the standard version it contains all the classes and methods you need for programming TCP/IP applications. This distinguishes Java as a favorite tool for creating applications which communicate with the Web-IO Digital.
Beyond a current Java environment no additional resources are needed for running.
As the successor to Borland Delphi, Delphi 2005 builds on the Microsoft.net Framework. Delphi 2005 (Delphi.net) offers everything needed to program TCP/IP applications. This makes Delphi 2005 a favorite tool for creating applications that communicate with the Web-IO Digital. Additional drivers or DLLs are not required.
As an easy to learn higher language Delphi offers everything you need for programming TCP/IP applications. This also makes Delphi a favorite tool for creating applications that communicate with the Web-IO Digital. Additional drivers or DLLs are not required.
Visual C++ was until recently one of the most widely used development platforms for creating Windows applications. But in the meantime, more and more programmers are working with the .Net Framework and creating their applications in C#.Â
Visual C++ is one of the most used development platform for creating Windows applications.
As successors to MS Visual Basic and VB.Net there are now VB 2005 and 2008. They also offer everything needed for programming TCP/IP applications. This makes Visual Basic 2005 / 2008 a favorite tool for creating applications that communicate with the Web-IO Digital, especially since the Express version of VB 2008 was offered from Microsoft free for downloading. Additional drivers or DLLs are not needed.
As an easy to learn higher language Visual Basic offers everything you need for programming TCP/IP applications. This also makes Visual Basic a favorite tool for creating applications that communicate with the Web-IO Digital. Additional drivers or DLLs are not required.
The Internet browser is today part of every modern operating system and is valued as a versatile display instrument for surfing the Internet.
In this tutorial the JavaScript MQTT client from the Eclipse-Paho Project will be used to create an individual interface for the Web-IO 4.0 Digital.Â
Here the states of the Web-IO are buffer stored as a retained message with the broker and represented by the Web client in a simple HTML table.
When one of the outputs is clicked on, the Web client sends an MQTT Publish which instructs the Web-IO to switch the corresponding output.
