Implicit Messaging (Cyclic data)
The stack offers an interface to access the cyclic data.
The cyclic data is is available in the dual-port memory (DPM) which can be accessed by a host application.
Explicit Messaging (Acyclic data)
Acyclic services to 'build in' CIP objects (CIP objects that belong to the default CIP object dictionary of the EtherNet/IP Adapter firmware) are handled by the firmware itself.
In addition to the 'build-in' CIP objects other CIP objects or vendor specific CIP objects can be registered at the firmware, e.g. to support special CIP profiles. In that case, all acyclic services need to be handled by the host application.

Description
The EtherNet/IP Adapter firmware implements all CIP objects and services to build an EtherNet/IP Adapter device that can pass ODVA's conformance test. This also requires a correctly behaving host application in addition.
Configuration
...
