R & D of Data Acquisition and Real-time Monitoring System of SAWL Pipe Production Line

Based on full knowledge and analysis of manufacturing process flow and control requirements of the SAWL pipe production line，and taking relevant possibility and effectiveness of technological realization into consideration，the R & D of the data acquisition and real-time monitoring system of the said production line is completed by means of materialization of the data communication between WinCC 7.0 and PLC via the industrial Ethernet technology and the OPC technology.Relevant functions of the said system as successfully developed cover such aspects as dynamic monitoring of workshop material distribution status，real-time monitoring of equipment start/ stop status，real-time trend of equipment key parameters，and alarming of equipment parameters.Moreover，the remote access to the system via the IE browser is realized on the basis of the Web publishing technology.
