由于多个 IP 地址导致的错误 当。。。的时候 PROFINET 控制器启动，它检查网络是否有重复的 IP 地址。尽管实际上没有重复的地址，但建立连接的操作可能会因错误消息“ARP 多个 IP 地址”而中止。在同一网络中具有多个以太网端口的 Linux 系统可能会受到这种“ARP 通量”效应的影响。 这可以使用以下命令进行纠正： sysctl -w net.ipv4.conf.all.arp_an

认证注意事项 这 CODESYS PROFINET 控制器和 CODESYS PROFINET 根据当前有效的 PI 一致性测试版本持续检查设备。然而，一个 PROFINET 产品认证始终且专门适用于整个系统。整个系统由硬件平台和“固件”组成，“固件”包括操作系统、 CODESYS 运行时系统，以及 PROFINET 成分。 数据表为 PROFINET 控制器和 CODESYS PROFINET
