Abstract This paper introduces two sets of independent PLC system, in which the heating furnace electric control system uses the PLC of Siemens S7-400, the other PLC system is Siemens S7-300 which is in hydraulic power station used for hot charging.They are connected through the Profibus-DP bus. The PLC of S7-400 as master and the PLC of S7-300 as intelligent slave station, the HMI of hot charging hydraulic station is increased in the HMI of heating furnace, and the function of operation is retained at cabinet panel. This transformation method is successfully applied in Xiangtan Iron and steel company market volume production line heating furnace control system, good operation effect.
