Setting Up EtherNet/IP Implicit Messaging with Allen-Bradley PLCs
Implicit messaging has advantages and disadvantages. Implicit messaging is faster than explicit messaging and is therefore ideal for time-critical applications. However, data delivery is not guaranteed when using implicit messaging, so it is more suited to applications where occasional data loss is acceptable.
This guide describes how to set up implicit messaging (Cyclic and Change of State) with Allen-Bradley PLCs. The RSLogix 5000 programming tool is used.
