Abstract
This paper shows the advantages brought by network technology to production and management, through the application of network technology in press shop of Shanghai Volkswagen. The following items will be introduced: fieldbus, equipment operation based on TC/PIP, production management based on TC /PIP and managing system for the whole press shop.
The fieldbus replacing the traditional point to point connection, makes the equipment installation easier, shortens the installation and commission time, and decreases the opportunity of chaos by connection problem. Due to complexity of press equipment, we need to share some information between different operation panels. Thanks to network technology, this can be easily realized. The management of production line is acquiring data from PLCs of control, through the connection of Ethernet between PC and PLCs to store the data in one database in PC. Using the tools provided by database, the running of production line is analyzed. The managing system for the whole press shop is using the data from production line running, blanks, parts and dies for the production management to make production plans, which guaranties the JIT production of the shop
