摘　　要：从工程实际应用出发,在西门子可编程控制器(PLC)中封装速度给定积分器程序块,用来取代变频器中的速度给定功能,既有效地提高了控制编程的灵活性,又降低了变频器的运算负担。该程序块采用SCL语言编写,兼容性强,可方便移植到其他PLC中使用。程序块引脚参数设计简单实用,适用于多工况控制,性价比高,具有良好的参考和实用价值。Based on the practical engineering application,a program block of speed setting integrator was packaged in Siemens PLC to replace the speed setting function in frequency converter,which could not only improve the flexibility of control programming effectively,but also could reduce the computing burden of frequency converter.The program block is written with SCL language,and it is with strong compatibility and can be easily transplanted to other PLCs.The pin parameters of the program block are designed simply and practically,and it can be adapted to multi-operating condition control,which is cost-effective and owns good reference and practical value.
