An industrial control network with high accuracy should be established for measurement and setting out of batch of industrial components. The operation with online Total Stations on observation pillars has the advantages over one on tripods in velocity, accuracy and reliability. The platform must not be build for setting out . An industrial control network with 8 reinforced concrete observation pillars has been established in the steel structure workshop of the Baoji Bridge Plant in Shaanxi province. The directions of each station were obtained with PowerSet Total Station (2″)made by Sokkia CO.LTD., Japan,observing 3 observation sets. The 4 sides in the network were observed with a 3m invar levering staff served as "transverse baseline" and the Total Station. The network has the size of 6m x 18m, the average side of about 6m, and the determination accuracy of ±0.10 mm for horizontal positions and of ±0.05 mm for vertical positions have been obtained. The determination method of side was discussed, and evaluation of the accuracy of side was performed. The network has been successfully used to set out the components of the Yangtze River bridge in Wuhu city , Anhui province.
