  • Page 27 Ethernet destination addresses. See Producer/Consumer Communications Model. Object A CIP node is modeled as a collection of Objects. An Object provides an abstract representation of a particular component within a product. The realization of this abstract object model within a product is implementation dependent. In other words, a product internally maps this object model in a fashion specific to its implementation.

EtherNet/IP was introduced in 2001 and today is the most developed, proven and complete industrial Ethernet network solution available for manufacturing automation, with rapid growth as users seek to harness the advantages of open technologies and the Internet.

ControlNet, EtherNet/IP and DeviceNet are defined respectively as CP 2/1, CP 2/2 (CP 2/2.1 with CIP Sync), and CP 2/3.

Originally, Ethernet worked in a half-duplex mode of operation, meaning that a node could send or receive data, but it could not do both at the same time.
  • Page 82 EXM58 • EXO58 EtherNet/IP This data format is used to implement the Media Access Control (MAC) protocol that allows a device to "talk" on the Ethernet network. Each MAC device has a unique Source Address (SA) comprised of a 6-byte number (48 bits or 12 hexadecimal digits) that was assigned to it at the time of manufacture.
  • Page 83 EXM58 • EXO58 EtherNet/IP Ethernet-based system must be assigned an IP address. This is most commonly identified by the four-byte address listed in the “network properties” on personal computers that use TCP/IP as their Ethernet network connection (e.g., 192.168.1.10).
