S7-300之间的以太网通讯

问题：通过CP343-1模块，如何实现2套S7-300之间的以太网通讯？解答：我们首先搭建一套测试设备，设备的结构图如下：2套S7-300系统由PS307电源、CPU314C-2DP、CPU314C-2PTP、CP343-1、CP343-1IT、PC、CP5611、STEP7组成，PLC系统概貌如下图：如下将向您一步一步展示如何实现2套S7-300之间的以太网通讯:第一步：打开SIMATICManager，根据我们系统的硬件组成，进行系统的硬件组态，如图:插入2插入2个S7300的站，进行硬件组态:卜IhU匸卜-［I呂口」E「wdriEii：Ei¥e£—net上託［呂口_驚靶「1討］目FieEdtInsertPLCVewOptionfWindowHmp口］囲謁剧_FT生|%反注|希|||VWFilter〉日弐I5u_scndrecciveEl日弐I5u_scndrecciveEl圃Bthamed由■•圈CPU314C-2FTP
