This makes site independent monitoring, visualization, remote maintenance and control of processes possi- ble.WAGO Kontakttechnik GmbH is a member of IAONA Europe, an organi- zation with the purpose of establishing ETHERNET in automation technology.
Page 267 The “T” and “F” stand for ‘twisted pair’ and ‘fiber optic’, and sim- ply indicate the cable type. 10Base-T 10Base-T Standard is used for the WAGO ETHERNET fieldbus coupler. This allows for simple and economical network architecture using STP/UTP cable as the transmission medium.
Page 268 This can also be viewed as a “data traffic cop” where the hub “polices” the data coming in and going out so that it will be transmitted to the correct node. WAGO recommends using a switch rather then a hub, this will allow for a more deterministic architecture.
Page 269 ETHERNET • 265 Network architecture 5.1.2 Network topologies In the case of 10Base-T several stations (nodes) are connected using a star to- pology according to the 10Base-T ETHERNET Standard. Therefore, this manual only deals with the star topology, and the tree topology for larger networks in more detail.
Page 270 266 • ETHERNET Network architecture 5-4-3 Rule A consideration in setting up a tree topology using ETHERNET protocol is the 5-4-3 rule. One aspect of the ETHERNET protocol requires that a signal sent out on the network cable must reach every part of the network within a speci- fied length of time.
Page 271 ETHERNET • 267 Network architecture 5.1.3 Coupler modules There are a number of coupler modules that allow for flexible arrangement for setting up an ETHERNET network. They also offer important functions, some of which are very similar. The following table defines and compares these modules and is intended to simplify the correct selection and appropriate application of them.
Page 272 268 • ETHERNET Important terms 5.1.4 Important terms Data security If an internal network (Intranet) is to be connected to the public network (i.e. Internet) then data security is an extremely important aspect. Undesired access can be prevented by a Firewall. Firewalls can be implemented in software or network components.
Page 273 ETHERNET • 269 Important terms Shared ETHERNET Several nodes linked via a hub share a common medium. When a message is sent from a station, it is broadcast throughout the entire network and is sent to each connected node. Only the node with the correct target address processes the message.

Page 276 5.2.2.1 ETHERNET ETHERNET address (MAC-ID) Each WAGO ETHERNET fieldbus coupler is provided from the factory with a unique and internationally unambiguous physical ETHERNET address, also referred to as MAC-ID (Media Access Control Identity). This can be used by the network operating system for addressing on a hardware level.
Page 277 ETHERNET • 273 Network communication IP addresses To allow communication over the network each fieldbus node requires a 32 bit Internet address (IP address). Attention Internet addresses have to be unique throughout the entire interconnected networks. As shown below there are various address classes with net identification (net ID) and subscriber identification (subscriber ID) of varying lengths.
Page 278 192.000.000.XXX - Ca. 2 million Class C 223.255.255.XXX Each WAGO ETHERNET fieldbus coupler/controller can be easily assigned an IP address via the implemented BootP protocol. For small internal networks we recommend selecting a network address from Class C. Attention Never set all bits to equal 0 or 1 in one byte (byte = 0 or 255). These are re- served for special functions and may not be allocated.
Page 279 ETHERNET • 275 Network communication Subnet mask A subnet mask was introduced to encode the subnets in the Internet. This in- volves a bit mask, which is used to mask out or select specific bits of the IP address. The mask defines the subscriber ID bits used for subnet coding, which denote the ID of the subscriber.
Page 280 276 • ETHERNET Network communication Gateway The subnets of the Internet are normally connected via gateways. The function of these gateways is to forward packets to other networks or subnets. This means that in addition to the IP address and network mask for each net- work card it is necessary to specify the correct IP address of the standard gate- way for a PC or fieldbus node connected to the Internet.
Page 281 ETHERNET • 277 Network communication TCP segment The packet header of a TCP data packet is comprised of at least 20 bytes and contains, among others, the application port number of the transmitter and the receiver, the sequence number and the acknowledgement number. The resulting TCP packet is used in the data unit area of an IP packet to create a TCP/IP packet.

Page 321 Glossary • 317 Client A system that requests the services of another. With the aid of the service re- quest, the client can access objects (data) on the server. The service is pro- vided by the server. Coaxial cable This cable contains a single wire and a radial shield to transmit information. CSMA/CD Carrier Sense Multiple Access with Collision Detection.
Page 322 318 • Glossary ETHERNET Standard In 1983 ETHERNET was standardized by IEEE 802.3 10Base-5. ISO took over the standardization in the ISO Standard 8802/3. The essential differ- ences between ETHERNET and the IEEE standard are to be found in the frame architecture and treatment of pad characters.
Page 323 Glossary • 319 Hardware Electronic, electrical and mechanic components of a module/subassembly. Header A portion of the data packet, containing, among others, the address informa- tion of the receiver. Host computer / Subscriber Originally used to describe a central mainframe computer accessed from other systems.
Page 324 320 • Glossary IAONA Europe IAONA Europe (Industrial Automation Open Networking Alliance) is an or- ganization for industrial network technology with the objective to establish ETHERNET in automation technology. Further information on this subject is available on the Internet under: www.iaona-eu.com.
Page 325 Local Area Network. Library Compilation of modules available to the programmer in the programming tool WAGO-I/O-PRO 32 for the creation of a control program according to IEC 61131-3. Manchester encoding In this encoding system, a 1 is encoded as a transition from low to high and a 0 as a transition from high to low.
Page 326 322 • Glossary MS-DOS Operating system, which allows all applications direct access to the hard- ware. Open MODBUS/TCP specification Specification which establishes the specific structure of a MODBUS/TCP data packet. This is dependent upon the selected function code or from the selected function (readin/readout bit or register).
Page 327 Glossary • 323 A proxy can filter out individual data packets between the Internet and a lo- cal network to increase security. Proxies are also used to limit access to par- ticular servers. In addition, proxy gateways can also have a cache function, in which case they check whether the respective URL address is already available locally and return it immediately, if necessary.
Page 328 324 • Glossary Routing Method of selecting the best path over which to send data to a distant net- work. SCADA Abbreviation for Supervisory Control and Data Acquisition. SCADA soft- ware is a program for the control and visualization of processes. Segment Typically, a network is divided up into different physical network segments by way of routers or repeaters.
Page 329 Glossary • 325 S-UTP Screened unshielded twisted pair cable which only has one external shield. However, the twisted pair cables are not shielded from each other. Switch Switches are comparable to bridges, but with several outputs. Each output uses the full ETHERNET bandwidth. A switch switches a virtual connection between an input port and an output port for data transmission.
