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 typ-
ically 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. Receiving nodes decode
this key to know whether they must accept the data or not.
