Beaglebone Black上使用Codesys开发EtherCAT（二）
下载runtime到beaglebone1. 配置ip地址，Beaglebone上usb网卡的网络地址为192.168.7.2https://img-blog.csdn.net/20170729145152009?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvZ3Bfc2NvcHJpdXM=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast
2. 配置PC段USB网卡的网络地址为192.168.7.1，子网远吗为255.255.255.252（默认自动获取也可以）

3. 在serial使用ping192.168.7.1命令测试网络是否相同（不执行该命令可能导致不能正常扫描到设备）
4. 打开CodeSys软件
5. 点击工具->Update BeagleBone black，输入“网络地址”，“用户名”
