The inclusion of Ethernet TCP/IP communication on the factory floor is innovative comparing with IEC 61158 Fieldbus standards. This work presents the design and implementation of a Web-based data parameters acquisition system of electronic boards from production and quality engineer and, at the same time, using Ethernet TCP/IP and XML language to disseminate data over the Internet and send the data to the Manufacturing Execution System. By applying the standard World Wide Web protocol - HTTP, the remote user may monitor production performance and modify control parameters with the general Internet browser. The architecture of the system includes a instrumentation and control board, processing and communication unit (Rabbit RCM3200 board microcontroller wih Ethernet AX8879ds). The system also incorporates a local data base. The programming language selected was C using a preemptive kernel. The tests results show that Ethernet TCP/IP based control system start to be real-world applications.
