Terminology

 

 

 

Implicit (I/O

Data)

Connections are established to move application-specific I/O data at regular

Messaging

 

intervals. These connections often are set up as one-to-many relationships in

 

 

order to take full advantage of the producer-consumer multicast model.

 

 

Implicit messaging uses UDP/IP resources to make multicast data transfers

 

 

over Ethernet a reality.

 

 

Explicit Messaging

Point-to-point relationships that are established to facilitate request-response

 

 

transactions between two nodes. These connections are general purpose in

 

 

nature and can be used to reach any network-accessible items within a

 

 

device. Explicit messaging connections utilize TCP/IP services to move

 

 

messages across Ethernet.

 

 

 

EtherNet/IP

 

EtherNet/IP is the name given to the Common Industrial Protocol (CIP), as implemented

 

 

over standard Ethernet (IEEE 802.3 and the TCP/IP protocol suite).

 

 

User Defined Data

User-defined data types allow a user to organize the data to match a machine or process.

Type

 

This streamlines program development and creates self-documenting code that is easier

 

 

to maintain. A user-defined data type stores all the data related to a specific aspect of a

 

 

system. This keeps related data together and easy to locate, regardless of its data type.

 

 

Common Industrial

The Common Industrial Protocol (CIP) is a media independent, connection-based, object-

Protocol (CIP)

 

oriented protocol designed for automation applications. It encompasses a comprehensive

 

 

set of communication services for automation applications: control, safety,

 

 

synchronization, motion, configuration and information.

 

 

Connection Object

The CIP Connection Class allocates and manages the internal resources associated with

 

 

both I/O and Explicit Messaging Connections. The specific instance generated by the

 

 

Connection Class is referred to as a Connection Instance or a Connection Object.

 

 

Service Object

Service is a function supported by an object and/or object class. The Service Object

 

 

configured for a particular ICC ETH-1000 to a Mitsubishi device connection is used to

 

 

define what data transfer functions need to be executed.
