Abstract

The advent of internet simplified the comunication between remote systems, allowing the application of supervisory systems through the internet, mainly using the TCP/IP protocol. Although these systems have already been employed in industry, using the Programmer Logic Controller (PLC\'s) as driver, the implementation of any simple supervisory system could have an expensive cost, due to the prices of hardware and software employed. Moreover, the existing supervisory systems provide limited visual resources, restricted to the used software. So, this work presents a low cost supervisory system, via TCP/IP, applied to electric machines but it can be generalized in the supervision of differents types of systems, where the remote monitoring is necessary. Besides the conventional displaying of the monitored parameters through graphics and labels, the developed system allows the exhibition of the supervisioned parameters using eletronic panels, providing an alternative visual interface to the user so that their supervision becomes easier.
