欧姆龙PLCUDP命令FINS协议实验

1、ETN21以太网fins/UDP命令实验时间：2022年9月15日实验设备：CP1H-XA4ODR-ACP1W-EXT01 CJ1W-ETN21 网线实验目的：利用SOCKETTO发送UD命令，对CP内存进行读取和写入。实验步骤：1、IP地址设置：翻开电脑本地连接查看IP地址如下:usb线连上电脑，翻开I/O表，将ETN21模块的ip地址与电脑设置为同一 个网段不同节点，节点号跟硬件上的 node number 一样，下载重启模块，如 下：寺套裁| SBTP'I FQF削件地址|師件发送 收曲件|日芥申自动调整HTTP广椁CT 全 14. 3®SD 广全0辄那SDIf地址1Q
