6.1.4  Domain Table Setup 
To be able to communicate with other nodes on the LonWorks network, the FieldServer must have its Domain, Subnet and 
Node ID’s set. Explicit configuration requires the user to set these parameters. 
There are 3 ways in which the FieldServer DSN (Domain,Subnet,Node address) can be set: 
  Set the DSN using a Network manager by commissioning the FieldServer into the Network Manager Project.  When 
doing  it  this  way,  it  is  extremely  important  that  the  DSN is  not  forced in  the  FieldServer  Configuration,  as  the 
Configuration address will override the Network Manager Address every time the FieldServer is restarted. 
  Set the DSN from the Lon.ini file.  Using this option provides a default DSN if the FieldServer does not have a DSN 
assigned.    If  a  Network  Manager  or  the  FieldServer  Configuration  provides  a  DSN,  then  the  Lon.ini  DSN  will  be 
ignored. 
  Set the DSN in the FieldServer configuration.  This option takes precedence over the 2 other addressing options, and 
should therefore not be used when commissioning a FieldServer into a Network with a Network Manager. 
Example 1 - Setting the Domain and Subnet from the lon.ini file 
The Domain Table and Subnet IDs can be set from a lon.ini file on the FieldServer.  The FieldServer’s LonWorks Node ID will 
be set from the System_Station_Address field in the configuration file if specified, otherwise a default value will be used.
