5.2.6
Ethernet/IP Class 3 communication — Explicit messaging
General overview
Explicit messaging is a method of communication between EtherNet/IP PLCs and devices.
Explicit messaging uses Ethernet TCP/IP messages.
Explicit messaging is not cyclic in nature. The PLC and the devices must send individual
messages to each other.
Message delivery is guaranteed.
Multicast addressing is not possible.
