摘　　要：介绍了自由口模式和通信协议;以S7-200系列PLC与FP93智能仪表通信为例阐述了用自由口实现整个程序设计的过程,并给出了部分设计的程序。该方案用通信的方法交换数据,连线少,信息量大,传输距离远,抗干扰能力强,是PLC与智能仪表、执行器等可靠交换数据的(好)方法,可极大提高PLC的控制能力及扩大PLC的控制领域。This paper instroduces free port mode and communication protocol firstly. Then taking communication between S7-200 and FP93 intelligent insrument for example,it expoundes how to realize the programming using free port mode and some notes as well as c.hart.This solution has many advantages such as fewer wires,more information,far transmission distance,better anti-jamming and so on.It is a good way that exchanges datas and can improve control capability and field greatly in PLC.
