Industrial controlled network appts. based on tandem server

The utility model discloses an industry controlled network apparatus based on a tandem server. The utility model solves the problems that the existing traditional control network has centralizing danger and slow reflection speed, and the products of different manufacturers and different types are difficult to be interconnected. This device has the advantages that the structure is simple, and the dander and the control are dispersed, while the operation and the administration are concentrated. The structural shape of multilayer assortment and autonomous cooperation realizes the networking between the isomeric equipment and different buses. The structure of this device is that an industry controlled network apparatus based on the tandem server contains the Ethernet communication controlling unit comprised by a PC computer, a PC computer external Ethernet switch and an industrial computer, and the field controlling unit comprised by a programmable controller and/or an intelligent instrument. The characteristic of the utility model is that two units are connected by the tandem server.
