Application for Web-IO Digital

Application for Web-IO Digital

Here we have described various applications for Control, Monitoring and Control - Digital

Programming Web-IO Devices - See the examples here

Wiesemann & Theis is one of the leaders in this field and offers unique quality products for automation solutions via the Ethernet.

Applications for Web-IO

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#. 

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.

Visualizing, checking and controlling

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.

Here a Google Maps map needs to be displayed!

The wide availability of the Internet opens up new possibilities in visualization of measurements and automation data. Whereas before all objects in a visualization had to come from the same source, today it’s easy to link content from third parties into your own application.

The Internet browser is today part of every modern operating system and is valued as a versatile display instrument for surfing the Internet.

as individual interface for Web-IO

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

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.

The Web-IO Digital also brings devices into the SNMP management system which have potential-free contacts. Using the Web-IO Digital for example leaks in the server room can be reported early. When water enters the Web-IO Digital immediately issues a warning via SNMP trap.

Visualization systems are often provided with information using OPC protocol. But not all components which are part of a system provided their status as an OPC item. Information is often only provided via potential-free contacts or digital signals.

The W&T Web-IO provides a bridge between Modbus TCP and the most common Web technologies.

In many cases logging of the progress of technical processes is needed:

  • When was a door opened, and when was it closed again?
  • How often was the beam of a photoelectric sensor interrupted during a particular time interval?
  • How long did a motor run?
  • ............

Increasingly stringent quality requirements demand increasingly precise operational data acquisition. But even independent retail establishments are becoming more interested in recording and evaluating data on customer frequency.
