PROFINET IO技术中的LLDP协议

The Application on LLDP in PROFINET Network

PROFINET IO是一种实时以太网技术。本文简单阐述了LLDP协议,详细的描述了LLDP协议在PROFINET网络中的作用,通过Wireshark获取的LLDP报文,并对LLDP报文的组成部分进行解释,着重说明PI组织自定义的部分。本文将会帮助自动化工程师加深对PROFINET通信的理解。

PROFINET is a technology on industrial Ethernet. This paper describes the LLDP in a simply PROFINET IO system, and focus on the LLDP packet deeply and the components in the LLDP frame via Wireshark. It will help engineers understand the PROFINET IO communication.
