EtherNet/IP features overview
The CIP application layer defines a set of application objects and device profiles that define common interfaces and behaviors. In addition, CIP communication services enable end-to-end communication between devices on the different CIP networks.
EtherNet/IP maps the CIP communication services to Ethernet and TCP/IP, enabling multi-vendor interoperability between devices on Ethernet as well as with the other CIP networks.
EtherNet/IP defines two primary types of communications:
Cyclical Exchanges (Implicit Exchanges)
Messaging (Explicit Exchanges)
