摘要
在以S7-1200为核心的控制系统中,输入/输出部分用以接收信号或输出信号,便于与PLC进行人机对话。输入的有条码读入器,输入模拟量的电位器等;输出的则有打印机、编程器等。随着技术进步,这种设备将更加丰富。通过自动分拣装置的实现,可以进一步将S7-1200应用到以前使用S7-200的任何场合中去。
In the the control system with the core of S7-1200,the input / output section can be used to receive the signals or output the signals with PLC to facilitate man-machine dialogue.The input devices include bar code,analog input potentiometer,etc,while the output devices are printers,programming devices,etc..As technology advances,the devices will become more abundant.Achieved through the automatic sorting device,S7-1200 can be further applied to t any occasion which is previously used by S7-200.
