IP-addressing For the IP addressing the typical operation of private addresses is recommandedVaried address spaces are availableClass A 10000 to 10255255255 (max 16 million participants)Class B 1721600 to 17231255255 (max 65000 participants)Class C 19216800 to 192168255255 (max 255 participants)For small networks a Class B address is recommanded that avoids possiblebottlenecks for an extension of the network Also a logical structure is represented bythe IP addressesThe IP stack used on the module doesnrsquot allows a Class B subnet mask (25525500)for Class C addresses but for a class B address a Class C subnet mask (25525500)could use This means that a network with an 192168xx address is limited to 255participantsContinuing networkparameterizationYou can add a device to a project in which part of the station has already beenparameterized as described in item 33 First find the device in the New devicessubnet after opening the System Configurator and then integrate it into an existingsubnet by dragging it with the mouse deviceIP-address Scheme Think about a logical structure within your substation for example every device insubstation 1 has IP-address 172161x reserve an IP-address range for the Ethernetswitches for example 1-10 so the 1st switch in every substation has address17216x1 for the 1st SIPROTEC ring reserve 11-40 for a second 41-70 etc so youknow that 17216316 is the IP-address of the 6th SIPROTEC device in the 3rdsubstationAlso reserve an IP-address range for your devices in the control center room etcSuch kind of logical scheme makes your life much easier in case of maintenance orfault clearanceNTP clock server The NTP servers are integrated as Other IEC 61850 communicators via an ICD Filewhich is included in the DIGSI4 CD 2 NTP servers are supported The primary server
