The paper refers to a technical study for the modernization of existing complex mechatronic measuring systems in order to add functions as remote monitoring maintenance. The complex measuring system performs dimensional control and marking function for one subassembly of an automobile system. The Internet provides a low cost way to connect a computer anywhere in the world. Any computer that can connect to a local Internet Service Provider (ISP) and communicate with any other industrial equipment with local network?. With the Internet access the system have facilities to remote monitoring and telemaintenance control. This came with the introduction of the networking administration and protocols. Using these technologies for Predictive Maintenance professionals can improve the performance and dependability of any industrial plant. This particularly interesting technique to optimize “the after-sales service”of an automated installation appeared at the end of the seventies. Gabriel and Pimor (1985) presented one of the first applications in this field : Digital Equipment put a telediagnosis center into service first in the States in 1977, then in France in 1980. Realizing the need for such a maintenance approach for both the installer and the user, the firm integrated a specific micro-computer into every system. This micro-computer served as an intermediary between the end system and the diagnostic center. A specialized console and modem were installed free of charge at the customer’s end. Any communication costs were charged to Digital and the maintenance contract amount was reduced by 10 %. This telediagnosis system was first used for corrective maintenance. A 90 % success rate was achieved without the intervention of a nonsite technician [7] Using the Internet should be a different logic, whose central axis is not only a more efficient individual companies, but it merged with the maintenance and service environment.
