Remote maintenance management for the Lyon subway in France
The first Modicon/Telemecanique brand PLCs have been installed as part of a project to renovate the data transmission control system for the Lyon subway system. A total of 84 Premium PLCs communicating via Ethernet TCP/IP will be delivered by 2001. They will make it possible to process information relating to stations, energy management, monitoring and supervision of train traffic. In addition, the integration of the Web Server function will enable remote maintenance management.
