At present, the most important use of industrial Ethernet is in the management layer and the control layer. And with special real-time Ethernet technology, in motion control applications, application requirements with response times of less than 1ms can be met. For example, CIPsync, ProfiNetIRT and ETHERNETPowerlink have implemented such applications, so real-time problems can be considered to have been resolved. The situation of security issues is similar. The basic problem is an appropriate security protocol based on Ethernet transmission, such as Profinesafe based on Profinet and CIPSafety based on EtherNet/IP.
