ETHERNET ï 111Network CommunicationWAGO-I/O-SYSTEM 750ETHERNET TCP/IP• Class C: (Net-ID: Byte1 - Byte3, Host-ID: Byte4)e.g.: 201 . 16 . 232 . 2211000101 00010000 11101000 00010110110 Net-ID Host-IDThe highest bits in Class C networks are always 110.Meaning the highest byte can be in a range of110 00000 to 110 11111.Therefore, the address range of Class C networks in the first byte is alwaysbetween 192 and 223.Additional network classes (D, E) are only used for special tasks.More informationA more detailed description of these principles is found on the Internet underhttp://www.WuT.de/us_printmed.html (W&T, Manual TCP/IP-ETHERNET forBeginners).Key dataAddress range of the Possible number ofsubnetwork networks Subscribers per networkClass A 1.XXX.XXX.XXX -126.XXX.XXX.XXX127(2 7)Ca. 16 Million(2 24)Class B 128.000.XXX.XXX -191.255.XXX.XXXCa. 16 thousand(2 14)Ca 65 thousand(2 16)Class C 192.000.000.XXX -223.255.255.XXXCa. 2 million(2 21)254(2 8)Each WAGO ETHERNET fieldbus coupler/controller can be easily assignedan IP address via the implemented BootP protocol. For small internalnetworks we recommend selecting a network address from Class C.AttentionNever set all bits to equal 0 or 1 in one byte (byte = 0 or 255). These arereserved for special functions and may not be allocated. Therefore, the address10.0.10.10 may not be used due to the 0 in the second byte.If a network is to be directly connected to the Internet, only registered,internationally unique IP addresses allocated by a central registration servicemay be used. These are available from InterNIC (International NetworkInformation Center).AttentionDirect connection to the Internet should only be performed by an authorizednetwork administrator and is therefore not described in this manual.
