EtherNet/IP Communications Profile
COS I/O Connection
COS (Change Of State) I/O Connections establish event-controlled connections. This means that the
EtherNet/IP devices generate messages as soon as a change of status occurs.
Cyclic I/O Connection
Messages are triggered time-controlled in Cyclic I/O connections by means of a time generator.
UCMM
The EtherNet/IP gateway offers the option of establishing explicit messaging via the UCMM port
(Unconnected Message Manager Port).
UCMM-based explicit messaging is normally used for random, non-periodic requests.
It is not recommended for frequent messaging because the UCMM input queue in a product is typically
limited to just a few messages. Once this limit is reached, subsequent requests are ignored and must
be retried.
Connected Explicit Messaging
CIP is a connection-based system. For most communications between nodes, a connection is used.
A connection is a path or a virtual circuit between two or more end points in a system. The purpose is
to transfer data in the most efficient manner possible.
The Connection ID is a number that is associated with a communication relationship. Receiving nodes
decode this key to know whether they must accept the data or not.
