Abstract

The implantation of the Internet technologies in the industrial world is a reality that grows of exponential form. This paper presents the design and implementation of an application for real-time visualization of the state and the program of Programmable Logic Controllers (PLCs), using Java and Extended Mark-up Language (XML) technology. This application allows the visualization of PLC programs without the programming software. This visualization follows the IEC 61131 standard for PLC programming. The application is written in three versions: Applet, Java application and Web application. It is possible the simultaneous visualization of several PLC programs.
