ABSTRACT The programmable controller is designs the manufacture for the industrial control application the special purpose computer control device, is one kind of control device which the 1960s developed. The PLC movement in industrial control's near 40 years, to raised equipment's service factor to play the influential role. With the lapse of time, PLC already no longer limited to initial century logic and the sequential control domain, more and more PLC products turn toward satisfy the more complex control requests to make great strides forward. Appears along with the field bus and the industry ethernet technology and promotes, more powerful promotion PLC product in industrial field widespread use. Like PLC is also quite widespread in the power plant boiler control system's application, like PLC in strip pickling control application and so on; This topic mainly aims at PLC in the strip pickling system's application design, reduces the labor intensity, maintains is more convenient, the reliability and throws transporting rate to enhance unceasingly. This will bring a better economic efficiency to the industy. Key words programmable controller, strip pickling, logix5000 Programs the software 目 录 摘 要 I 1 绪论 1
