CONTRIBUTION FOR THE DEVELOPMENT OF A WEBSERVER INTEGRATED INTO PROGRAMMABLE LOGIC CONTROLLER FOR A HEATING SYSTEM PROCESS VIEWING.

Automation of industrial installations is an assembly of mechanical and electrical equipment that can generate logical commands, through a software program, in order to replace the manual orders made by human operators. At present, there are automation systems such as PLC, DCS (Distributed Control System), HMI (Operator Interface), SCADA (Data Control and Acquisition System), ANN (Artificial Neural Networks) and more. Siemens has integrated into the standard PLC with Ethernet communication interface, a web server able to reading the tags from it and displaying them on a customizable HTML page. This web page can be accessed from within the network where it is located and from the outside of the network, a VPN connection, from a web-browsing device, accessing via the IP address of the PLC.
