In Token Ring networks a token is passed around the network (configured in ring topology ), allowing the owner of the token to transmit a frame, to avoid collision.Token Ring networks vanished from networking industry long way back.A 100Mbps Ethernet interface is called a FastEthernet interface and a 1000Mbps Ethernet interface is called a GigabitEthernet interface.Examples of virtual interfaces are Loopback interface and Null interface.Only the lack of a widely accepted, flexible application layer targeted to Industrial Automation has prevented its complete acceptance.

Heres the top 6.5 things you need to know about EtherNetIP. Note: David Letterman has his Top Ten. Im only 65 as good as David Letterman) 1) EtherNetIP is an application layer protocol that is transferred inside a TCPIP Packet. That means that EtherNetIP is simply the way data is organized in a TCP or UDP packet. For information on what TCP or UDP is get my Industrial Ethernet Book. Difference Between Fast Ethernet And Serial Interface Series Of DataAll devices on an EtherNetIP network present their data to the network as a series of data values called attributes grouped with other similar data values into sets of attributes called Objects. There are EtherNetIP Required Objects Identity, TCP, Router that every device must have. The EtherNetIP Specification defines those objects. There are EtherNetIP Application Objects that have the data for your specific device. EtherNetIP devices that support specific devices all have the same set of EtherNetIP application objects. There are two kinds of messages that are transferred between an EtherNetIP Scanner Device (opens connections and initiates data transfers) and EtherNetIP Adapter devices (provides data to Scanners). These messages are Explicit Messages (asynchronous, as needed) and IO Messages (Data messages that are continuously transferred). EtherNetIP is part of CIP, the Common Industrial Protocol. CIP defines the Object structure and specifies the message transfer. CIP protocol over Ethernet is EtherNetIP. Our company, RTA, is the leading supplier of EtherNetIP technology. Difference Between Fast Ethernet And Serial Interface Free EtherNetIP SourceRTA can supply Royalty Free EtherNetIP Source Code Software stacks, EtherNetIP PCBs, and Modules. Now for some details A LITTLE ETHERNETIP BACKGROUND Most people who work in an office associate the term Ethernet with the physical cable behind their desk. This cable connects their office PC to the printers and servers of the local network and the infinite web sites on the Internet. This cable is only the physical part of Ethernet, the media carrying Ethernet messages to your PC. This suite of protocols works well for the office environment. It allows users to share files, access printers, send email, search the Internet and perform all the other communications used in the office environment. The needs of the factory floor are much different with some very special requirements. Instead of accessing files and printers, factory floor controllers must access data embedded in drive systems, operator workstations and IO devices. ![]() Terminating the fill operation on a bottle requires much more time-precise communications than accessing the next page of an Internet site. Traditionally, Ethernet had only limited acceptance in Industrial Automation. Until recently the expense, lack of intelligent switches and routers and the domination of large vendors with proprietary protocols prevented the wide acceptance of Ethernet on the factory floor. Now with prices falling, PCs with inherent Ethernet capability moving in droves onto the factory floor and intelligent switches and routers, Ethernet is gaining acceptance.
